The best AR stock
Quick answer: the Magpul CTR Mil-Spec (around $65) is the best AR-15 stock for most people. Magpul lists it at 8.9 oz, with a friction lock that clamps it to the buffer tube to cut wobble, an integral QD sling socket and a length of pull from about 10.3 to 13.6 inches; reviewers on OpticsPlanet rate it 4.9 out of 5 from 288 reviews. Its limit is that the lock cannot fix every tube. For a wider cheek weld, the B5 Systems Bravo (around $60), or the B5 Enhanced SOPMOD if you also want battery storage. For a precision AR-15 or AR-10, the fixed Magpul PRS GEN3. The Hogue OverMold (around $50) is the budget pick, and the Mission First Tactical Battlelink Minimalist has the lightest published weight here, 5.8 oz. All six are listed for Mil-Spec buffer tubes: check yours first.
A buttstock sets how the rifle meets your shoulder and cheek, so the right one depends on three things: the size of your buffer tube (Mil-Spec or commercial), how much cheek support you want, and whether the rifle is a carbine you carry or a precision rifle you shoot from a rest. Every card names the exact model we checked. We read the maker's own page for Magpul, B5 Systems and Mission First Tactical; Hogue's site was blocked to us, so the Hogue specifications are labelled as the retailer listing's.

Our picks
Best AR stock overall: Magpul CTR Carbine Stock, Mil-Spec
Collapsible · fits Mil-Spec carbine tubes only · friction lock · QD socket · 8.9 oz (Magpul) · card: MAG310-BLK, black
around $65exact price on OpticsPlanet
The stock most AR-15 owners should buy first. Magpul lists the CTR at 8.9 oz, with a length of pull from about 10.3 to 13.6 inches on an M4 carbine tube, and its signature part is a supplemental friction lock: a second lever that clamps the stock to the tube to cut the wobble a standard collapsible stock has. It adds an integral QD sling socket and two footman's loops, a rubber butt-pad, and Magpul makes it in the USA. It is the largest owner record on this page, 288 reviews, and only two of them say they would not recommend it. Owners praise the friction lock most, along with the QD socket, the easy install and the price. The honest limit is in the retailer's own feature list: friction lock performance varies with the tube's dimensional tolerances, and a few owners with Smith and Wesson factory tubes still report play, one of them with the lock engaged. It fits Mil-Spec tubes only, and one reviewer warns that "the Milspec stock WILL NOT fit over the commercial tube".
Pros
- Friction lock clamps the stock to the tube to reduce wobble, the feature owners praise most
- Integral QD sling socket plus two footman's loops (Magpul)
- Light at 8.9 oz, with a slim, snag-resistant A-frame profile
- Only two of 288 reviews say they would not recommend it
Cons
- The lock does not tighten every tube: one owner writes "Even with the clamp engaged, the stock still rattles considerably" on an S&W M&P 15-22
- Mil-Spec tubes only; this model will not fit over a commercial tube
- Slim cheek rest; Magpul says its snap-on risers are for fully-extended stocks or non-AR15 rifles
- No storage and a thin 0.3 inch butt-pad; one owner was "hoping for a little more cushion."
Best for: almost any AR-15 or AR carbine on a Mil-Spec tube, especially if your current stock rattles. If you want a wider cheek rest, look at the B5 Bravo or SOPMOD.

Best cheek weld on a slim stock: B5 Systems Bravo Stock, Mil-Spec
Collapsible · fits Mil-Spec carbine tubes · QD and fixed sling mounts · no storage · 9.3 oz (B5 Systems) · card: BRV-1085, Flat Dark Earth
around $60exact price on OpticsPlanet
The pick for a fuller cheek weld without the bulk of a SOPMOD. B5 Systems lists the Bravo at 9.3 oz and 2 inches wide, and says it leaves out the SOPMOD's storage to give a slimmer profile. The retailer lists four sling points, fixed sling mounts plus steel anti-rotation QD mounts, and a cushioned non-slip butt-pad with a holder for an M4 Multi-Tasker tool (sold separately); B5 makes it in the USA and backs it with a limited lifetime warranty. Owners bring up the cheek weld more than anything, and only two of 215 reviews say they would not recommend it. The trade-off is fit. It has no friction lock, and on some Mil-Spec tubes it goes on very tight: the most helpful critical review warns "you better get ready because it goes on TIGHT". Other owners report the opposite, a little slop, so fit depends on your tube.
Pros
- Wide, comfortable cheek weld is the most praised feature in its reviews
- Four sling points, including steel anti-rotation QD mounts (retailer listing)
- Limited lifetime warranty and made in the USA (B5 Systems)
- Only two of 215 reviews say they would not recommend it
Cons
- Fit varies by tube: several owners call it extremely tight, others report "a slight slop when wiggled"
- No friction lock to take up play the way the Magpul CTR does
- No storage compartment (B5 dropped it for the slimmer profile)
- FDE shade: one owner calls it "by far the lightest/pale color FDE I’ve seen"
Best for: shooters who want a fuller cheek rest than the Magpul CTR at a similar weight. If you also want battery storage, the SOPMOD is the same idea with compartments.

Best for cheek weld and battery storage: B5 Systems Enhanced SOPMOD Stock, Mil-Spec
Collapsible · fits Mil-Spec carbine tubes · dual water resistant storage compartments · 12.2 oz (B5 Systems) · card: SOP-1076, Coyote Brown
around $95exact price on OpticsPlanet
The widest published width here and the only stock with storage. B5 Systems says the Enhanced SOPMOD builds on the Crane NSWC designed SOPMOD buttstock, and lists it at 12.2 oz and 2.4 inches wide, with dual water resistant storage compartments that owners use for batteries. Like the Bravo it has fixed sling mounts, steel anti-rotation QD mounts and a cushioned butt-pad with a tool holder, it is made in the USA, and B5 gives it a limited lifetime warranty. Owners praise the cheek weld and the storage tubes, and several run it on MK18-style builds. It is also the heaviest collapsible stock here by published weight, and the bulkiest, and its fit problems are the sharpest on the page: the most helpful critical review found it "once installed with force, could not move at all" on a Bushmaster tube, though most readers voted that review unhelpful. Four of 100 reviews say they would not recommend it.
Pros
- Dual water resistant storage compartments, the only storage on this page (B5)
- The widest published width here, 2.4 inches (B5)
- Four sling points, including steel anti-rotation QD mounts (retailer listing)
- Limited lifetime warranty and made in the USA (B5 Systems)
Cons
- The heaviest published weight among the collapsible stocks here: 12.2 oz per B5, 11.8 oz per the retailer
- Tight fit on some tubes: owners report hard adjustment, and one had to cut the tube off
- Battery caps can bind: one reviewer writes "the battery compartment caps are near impossible to rotate."
- Bulky: one owner who liked it still sent it back because "it is quite large and bulky"
Best for: a rifle carrying a battery-powered optic or light, and shooters who want the widest, most supported cheek weld. For less weight and bulk with a similar cheek, the Bravo.

Best precision AR stock: Magpul PRS GEN3 Precision-Adjustable Stock
Fixed, adjustable · optimized for rifle-length tubes · 1.4 in LOP and 0.8 in cheek adjustment · 27.8 oz (Magpul) · AR-15 and AR-10 · card: MAG672-BLK, black
around $240exact price on OpticsPlanet
The stock for a precision AR-15 or AR-10, and a different kind of stock from the rest of this page: it does not collapse. Magpul lists 1.4 inches of length of pull adjustment and 0.8 inches of cheek height adjustment, both set with tool-free aluminum knobs, a rubber butt-pad that adjusts for height and cant, a butt-plate that resists recoil up to .50 BMG, front and rear QD sockets and M-LOK slots underneath for a monopod. It is optimized for rifle-length tubes, and Magpul says it may also accommodate Mil-Spec M4 carbine and many A5-length tubes, and Magpul makes it in the USA. Owners praise how solid it is and how the knobs lock in place, and the most helpful review, from a Ruger Precision Rifle owner, says the weight gives it better balance. The costs are real: it weighs 27.8 oz, it is by far the most expensive stock here, and several owners find even its shortest length of pull too long; one reviewer writes "Fully collapsed this stock is longer than many fully extended stocks".
Pros
- Tool-free knobs for length of pull and cheek height, with positive click detents
- Butt-pad adjusts for height and cant; butt-plate rated for recoil up to .50 BMG (Magpul)
- Front and rear QD sockets plus bottom M-LOK slots for a monopod
- Fits AR-15 and AR-10 rifles; 237 of 244 reviews say they would recommend it
Cons
- Heavy: 27.8 oz, about three times the Magpul CTR (Magpul)
- Long minimum length of pull, about 14.4 in on an M4 tube per Magpul
- Using the cheek riser can push the scope back over the charging handle, "making the charging handle very difficult to manipulate"
- The most expensive stock here by far, and owners report fit problems on some enhanced or commercial tubes
Best for: a precision, DMR or bench AR-15 or AR-10 shot prone or from a rest, where adjustability beats weight. For a carbine you carry, pick a collapsible stock.

Best budget AR stock: Hogue OverMold Collapsible Buttstock, Mil-Spec
Collapsible · fits Mil-Spec tubes (1.15 in diameter) · rubber overmold · anti-rattle fit (retailer listing) · card: 15040, black
around $50exact price on OpticsPlanet
The budget pick, and the only stock here with a rubber overmolded cheek. The retailer lists a skeletonized reinforced polymer body covered in Hogue's rubber overmold, an anti-rattle and beard-safe design, a rubber and polymer hybrid butt-pad, multiple swivel and sling positions, a precision fit for Mil-Spec buffer tubes of 1.15 inch diameter, and USA as the country of origin. It matches Hogue's OverMolded grips and forends. Hogue's own site was blocked to us, so no weight is given. Owners like the rubber cheek, the tight fit and the price, and only two of 242 reviews say they would not recommend it. The same tight fit is its trade-off: several owners say it takes force to adjust at first, and one writes it "requires some force when you want to change the length of pull". Two reviewers report molding or sizing flaws, and the black version is the cheapest; the other colours cost more.
Pros
- Rubber overmold cheek, the comfort owners mention most
- Tight, anti-rattle fit on Mil-Spec tubes, per the retailer and many owners
- Matches Hogue OverMolded grips and forends
- Only two of 242 reviews say they would not recommend it
Cons
- Tight fit can make adjusting hard until it breaks in, per several owners
- No weight published on the listing, and we could not read Hogue's own page
- One reviewer reports the QD attachments "spin freely (twists your sling)"
- No storage: one reviewer writes "Wish it had some kind of battery storage."
Best for: a budget build, or a Hogue grip you want to match. If you adjust your stock often, the Magpul CTR slides more freely with its lock released.

Best lightweight AR stock: Mission First Tactical Battlelink Minimalist Stock, Mil-Spec
Collapsible minimalist · fits Mil-Spec 1.148 in tubes · QD point and sling slots · 5.8 oz (MFT) · card: BMSMIL, black
around $55exact price on OpticsPlanet
The lightest published weight on this page. Mission First Tactical lists the Battlelink Minimalist at 5.8 oz for Mil-Spec 1.148 inch diameter tubes, and backs it with a lifetime warranty. The retailer lists an angled non-slip rubberized butt-pad for faster presentation even with body armor, multiple sling slots with single point mounting, an ambidextrous QD sling point and an upper section for cheek weld. Owners mention the low weight more than anything else, and the most helpful review says it "Fits very snug so it doesn't rattle." The minimalist frame is the trade-off: there is no storage and little padding, one owner broke one clearing a double feed, and the most helpful critical review says "it feels and looks cheap". Fit runs both ways too, from very tight to a little wiggle. Five of 157 reviews say they would not recommend it.
Pros
- 5.8 oz, the lightest published weight on this page (MFT; the Hogue listing gives no weight)
- Ambidextrous QD sling point plus multiple sling slots (retailer listing)
- Lifetime warranty (Mission First Tactical)
- Angled rubberized butt-pad for presenting the rifle with body armor (retailer listing)
Cons
- Thin padding: one owner writes "There is very little padding but on a 556 you don't need any."
- Durability questions: one owner writes "I broke my first MFT stock pile-driving my weapon to clear a double-feed."
- Fit varies: some owners find it very hard to adjust, others report wiggle on their tube
- No storage compartment
Best for: a light carbine or SBR-style build where every ounce counts. For more cheek support at a few ounces more, the Magpul CTR or B5 Bravo.

Mil-spec vs commercial buffer tubes: check this first
An AR-15 collapsible stock slides on the receiver extension, the buffer tube behind the lower receiver, and there are two sizes. Magpul's own instruction card gives a Mil-Spec tube as approximately 1.15 inches in diameter, generally with a flat back, and a commercial tube as approximately 1.17 inches, usually with a slanted back, and say the easiest way to tell them apart is to measure the tube. The difference is small but decisive: a Mil-Spec stock will not slide over a commercial tube, and one CTR reviewer puts it plainly, "the Milspec stock WILL NOT fit over the commercial tube". All six stocks on this page are listed for Mil-Spec tubes. If yours is commercial, buy the commercial version of the stock where one exists, or replace the tube.
Mil-Spec is also a tolerance, not a single number, and that explains most of the complaints on this page. Owners of the B5 stocks, the Hogue and the MFT report both extremes on different tubes, from a fit so tight it is hard to adjust to a little wobble. The Magpul CTR's friction lock exists to take up that play, and even the retailer notes its performance varies with the tube's tolerances.
How to choose an AR-15 stock
- Match the buffer tube. Mil-Spec or commercial first, as above. The Magpul PRS GEN3 is optimized for a rifle-length tube and, per Magpul, may also accommodate Mil-Spec M4 carbine and many A5-length tubes.
- Decide how much cheek you want. The Magpul CTR and the MFT are slim. The B5 Bravo gives a fuller cheek rest at 2 inches wide, and the B5 SOPMOD has the widest published width here, 2.4 inches. The PRS GEN3 is the only one with a built-in adjustable cheek.
- Collapsible or fixed. A collapsible stock lets you shorten the rifle for storage, body armor or a smaller shooter. The PRS GEN3 is fixed and heavy, and several owners say its shortest length of pull is still long, so it belongs on a rifle you shoot from a rest.
- Weight. Published weights run from 5.8 oz (MFT) and 8.9 oz (Magpul CTR) to 12.2 oz (B5 SOPMOD) for the collapsible stocks, and 27.8 oz for the PRS GEN3.
- Sling points and storage. Every stock here has a QD sling point according to its maker or the retailer listing, except the Hogue, whose listing mentions sling positions and whose owners report QD sockets. Only the SOPMOD has storage.
- Wobble. If your current stock rattles, the CTR's friction lock is the one feature on this page designed to fix it.
How we chose these
This is a research-based roundup, not a hands-on test. We started from the retailer's AR-15 stock category sorted by most reviews and left out stock and grip kits so every card is a buttstock on its own. For each stock we opened the full model list to find the new, orderable model each card links to (used and demo units set aside) and read every review on the listing, including every low-star one. We checked specifications against the maker's own page for Magpul, B5 Systems and Mission First Tactical, and Magpul's instructions for the buffer tube sizes; Hogue's site was blocked to us, so the Hogue card uses the retailer's listing and says so. Claims we found only in secondary research, or only in marketing we could not confirm, were left out. Our scores are our opinion; ratings are shown attributed to the retailer that collected them. See our methodology for how we work.
FAQ
What is the best AR-15 stock?
For most AR-15s on a Mil-Spec buffer tube, the Magpul CTR. Magpul lists it at 8.9 oz with a friction lock that clamps the stock to the tube to reduce wobble, an integral QD sling socket and a length of pull from about 10.3 to 13.6 inches, and it carries 4.9 out of 5 from 288 reviews on OpticsPlanet. For a wider cheek weld, the B5 Systems Bravo, or the B5 SOPMOD if you also want battery storage. For a precision AR-15 or AR-10, the fixed Magpul PRS GEN3. On a budget, the Hogue OverMold, and for the lowest published weight, the Mission First Tactical Battlelink Minimalist at 5.8 oz.
How do I know if my AR-15 has a mil-spec or commercial buffer tube?
Measure the tube diameter. Magpul gives a Mil-Spec receiver extension as approximately 1.15 inches with a generally flat back, and a commercial one as approximately 1.17 inches with a usually slanted back. Every stock on this page is listed for Mil-Spec tubes; a Mil-Spec stock will not fit over a commercial tube, so a rifle with a commercial tube needs a commercial-size stock or a new Mil-Spec tube.
Magpul CTR or B5 SOPMOD: which is better?
They solve different problems. The Magpul CTR is lighter at 8.9 oz, slimmer at 1.7 inches, and has a friction lock to reduce wobble. The B5 Enhanced SOPMOD is 12.2 oz and 2.4 inches wide per B5, with a wider cheek rest and two water resistant storage compartments for batteries. Pick the CTR for a light, quiet carbine; pick the SOPMOD if you want the cheek support and storage. The B5 Bravo sits between them: the B5 cheek at 9.3 oz, without storage.
What is the lightest AR-15 stock?
Of the stocks on this page with a published weight, the Mission First Tactical Battlelink Minimalist, which MFT lists at 5.8 oz. The Magpul CTR is 8.9 oz and the B5 Bravo 9.3 oz. The retailer listing we used gives no weight for the Hogue, so it is not compared. The fixed Magpul PRS GEN3 is the heaviest here at 27.8 oz.
Does an AR-15 stock come with a buffer tube?
Not these. Each of the six listings names only the stock in its package contents, and Magpul states the CTR's receiver extension is not included. You install them on the buffer tube already on your rifle, which is why its size matters: all six are listed for Mil-Spec tubes, and the Magpul PRS GEN3 is optimized for rifle-length tubes.
