Primary Arms PLx 1-8x24 review: the Compact PLxC FFP RDB, Raptor or Griffin

By the OpticVerdict Editorial Team.
Research-based review · Updated 2026-10-04

How we reviewed it: a research-based review built from three OpticsPlanet listings of this scope (black Raptor, black Griffin, FDE Raptor), every owner review those listings show (5, 4 and 1), and Primary Arms' own product pages for parts 610210, 610221 and 610226 plus its launch announcement. Where the retailer and the maker name the scope differently, we use the maker's name. Third-party research leads we could not confirm on Primary Arms' site, including a battery hour rating, mounting figures and the history of earlier PLx models, were left out. We have not field-tested this scope; the score is our editorial opinion and owner ratings are shown attributed to their source. See how we evaluate.

Which scope this is: PLx, PLxC, Gen II and RDB

Searchers type "Primary Arms PLx", the retailer's listings say PLx Gen II and Compact PLx, and Primary Arms says Compact PLxC. They are describing one scope. Primary Arms sells part 610210 as the “Compact PLxC 1-8x24 FFP RDB Rifle Scope” with the ACSS Raptor 5.56/.308 Yard G2 reticle, and part 610221 under the same name with the ACSS Griffin MIL G2 reticle. OpticsPlanet titles the first one PLx Gen II Compact RDB 1-8x24mm and the second one Compact PLx 1-8x24mm, without RDB in the title; the part numbers match the maker's. A third OpticsPlanet listing (primary-arms-plxc) carries the flat dark earth Raptor version, which Primary Arms sells as part 610226.

PLx is Primary Arms' name for its top line. In its own words, “This LPVO is part of the top tier optics line called PLx.” RDB stands for Red Dot Bright. Primary Arms announced this version on its blog on June 4, 2025, and its product page says the PLxC 1-8x FFP Compact “now features RDB (Red Dot Bright®) diffractive reticle technology.” The retailer also lists second focal plane Compact PLx 1-8x24 versions and PLx scopes in other magnifications; those are different scopes and this page does not cover them. If you are deciding between Primary Arms tiers, our Primary Arms GLx review explains where PLx sits and why it contains no prism scope.

What Primary Arms claims for it

The pitch is a full 1-8x first focal plane scope in a short, light body. Primary Arms lists 9.28 in and 16.95 oz, a 30 mm tube, a field of view of 121 ft at 100 yards on the low end and 14.6 ft on the high end, and eye relief of 3.2 in to 3.7 in. Our compact LPVO guide uses the same 9.28 in and 16.95 oz and shows how that compares with other short LPVOs, including 1-6x designs that are longer.

The headline feature is the reticle illumination. Primary Arms says its Red Dot Bright diffractive design “is much more efficient than traditional etch-and-fill reticles” and delivers red dot brightness while keeping a first focal plane reticle, and that its AutoLive motion-sensing technology “helps to conserve battery life and ensures your reticle is visible the moment you need it.” The battery is a single CR2032. Primary Arms also lists Steel On Steel (SOS) adjustable turrets with 0.1 Mil clicks and 100 MOA of total elevation and windage adjustment, an easy-to-swap dovetail throw lever, and illumination adjustable down to night vision settings. That is the maker's description, not a measurement of ours; we found no battery hour rating on the Primary Arms pages we read, so we do not quote one.

What owners say about the black Raptor (610210)

The black Raptor listing has 5 reviews and we could read all of them. All five are five stars, and three carry the retailer's Verified Owner tag. The four dated reviews run from January 2026 to June 2026; the fifth sits in the retailer's Most Helpful box without a date. Four of the five praise the glass by name and the fifth calls the view pretty clear. The most helpful review compares it with the previous PLXc:

“The japanese glass is somehow better than the previous PLXc, crystal clear at 1x through 8x.”

Gary (UT), reviewer, via OpticsPlanet

The 1x view gets the next most attention. One Verified Owner writes “The 1x is almost like looking through a red dot with how the scope housing is so thin.” Another describes the same thing with both eyes open:

“That is also an amazing thing about this scope: at 1x, with both eyes open, the scope itself is barely perceptible when looking at your targets.”

Sooty (IN), verified owner, via OpticsPlanet

On the illumination, that owner writes “And yes, this thing is absolutely red dot bright even on 7/10 setting.” A second reviewer says “The illumination is excellent and the reticle is great at 1 and 8 power.” Not everyone cares about it: one Verified Owner says of the RDB brightness “I can take it or leave it if you want to save a buck and get the older version of this scope that doesn't have that option.”

The honest catches: price, a 3 mm exit pupil, a non-dot reticle, a small record

Price. This sits in the premium LPVO bracket, well above the budget and value picks in our best LPVO guide. The single reviewer on the FDE listing lists “Expensive” as the only con.

The reticle. The same owner who calls the 1x like a red dot writes “The reticle itself, not being an actual dot, is a weird adjustment to get used to.” They add that it is no trouble on targets at 100 yards and in. One owner, one opinion, but it is the only criticism of the reticle in the record.

Exit pupil at 8x. Primary Arms lists an exit pupil of 8 mm at 1x and 3 mm at 8x, which is what the arithmetic gives (24 mm divided by 8). This part is our reasoning, not a source: a 3 mm exit pupil leaves less room for your eye to be off center at full power than the 8 mm you get at 1x, so a consistent cheek weld matters more at 8x. None of the ten reviews we read complains about it.

The tube. The most helpful review names one wish, and answers it in the same sentence: “The only thing that could make it better would be a 34mm tube, but then it wouldn't weigh only a pound.”

A small owner record. The three listings hold 10 reviews between them, all five stars. That is a good sign, not proof.

Trade-offs, plainly

• Premium price for an LPVO; one reviewer lists “Expensive” as the only con.
• 3 mm exit pupil at 8x (Primary Arms, and 24 / 8 = 3) against 8 mm at 1x.
• One owner found the reticle, not being an actual dot, a weird adjustment to get used to.
• One owner wishes for a 34 mm tube while accepting the weight it would add.
• One Griffin owner lists “Made in japan” as a con, if country of manufacture matters to you.
• Only 10 owner reviews across three listings, and a single review on the FDE listing.

Which version: black Raptor, black Griffin or FDE Raptor

Primary Arms publishes the same length, weight, field of view and eye relief on its product pages for all three parts; what changes is the reticle and the finish. Each listing below keeps its own rating, its own reviews and its own price.

The FDE listing's retailer part number is PA-PLXC-1-8X24F-RDB-RAPTOR-5.56Y; Primary Arms sells the FDE Raptor version as part 610226 (SKU PA-PLXC-1-8X24F-RDB-RAPTOR-5.56Y-G2-FDE). Its rating is from our gather of that listing on August 17, 2026.

Black Griffin MIL G2 (610221)

The Griffin version (part 610221) is the same scope by Primary Arms' figures with a different reticle. Primary Arms describes it this way: “For those who prefer MIL units, the diffractive Griffin MIL G2 offers a full MIL grid with the iconic fast-acquisition horseshoe and chevron.” Primary Arms describes the Raptor G2 as a BDC calibrated for 5.56, .308 and similar cartridges. The same listing also sells an FDE row (part 610224) with the Griffin reticle.

Its owner record is 4 reviews, all five stars, under three reviewer names: two of the reviews are signed AP, Verified Owner from TX. The three dated reviews are from June to October 2026, all Verified Owner. The most recent explains how the reticle works for them:

“I really love the Griffin reticle because the big outer horseshoe functions just like a red dot for fast close-quarters shooting at 1x, while the clean MIL grid gives me precise holds for longer shots.”

GeneralKenobiWins (CO), verified owner, via OpticsPlanet

The same reviewer writes “the new RDB illumination is legitimately daylight bright”. The reviewer in the Most Helpful box writes “Windage and verticle adjustment dials have good endpoints.” One review signed AP says “I like it better than the ATACR”, and the other lists “Made in japan” as the con.

FDE Raptor

The flat dark earth Raptor version is sold on its own OpticsPlanet listing and is the PLxC card on our compact LPVO guide. Its owner record is a single five-star review from August 2026, so it is one opinion; the reviewer writes “The reticle and glass is very crisp.”, lists “Expensive” as the con and picks battle rifles as what it is best used for.

Raptor or Griffin: how to choose

Primary Arms describes the Raptor G2 as “Calibrated for 5.56, .308, and similar cartridges” with a Red Dot Bright horseshoe and chevron, and says it offers “full vertical and horizontal ranging stadia, as well as moving target leads and wind holds.” The Griffin MIL G2 is described as a full MIL grid with the same horseshoe and chevron.

• Pick the Raptor if you shoot 5.56 or .308 and want holds read straight off the reticle. One Raptor owner chose it for a 50-yard zero and the drop reticle over the Griffin.
• Pick the Griffin if you shoot another cartridge or prefer to calculate holds in mils; the turrets are 0.1 Mil either way.
• Pick the FDE Raptor if you want the Raptor in flat dark earth; the retailer also sells the Griffin in FDE.

The choice between them is our reading of Primary Arms' descriptions, not a test. Our FFP vs SFP guide explains why a first focal plane reticle's holds stay correct at every magnification.

Key specifications: black Raptor (part 610210)

Figures are from Primary Arms' product page for part 610210 unless marked as the retailer listing. The retailer's specification table for this listing agrees on 16.95 oz, 3.2 to 3.7 in of eye relief, 0.1 Mil clicks and 100 MOA of travel. On awards: we found none we could confirm on a primary source, so we claim none.

Should you buy it, and what else to consider

• Buy the PLxC if you want a first focal plane 1-8x that stays under 10 inches and about a pound, and the price is not the constraint.
• Skip it if budget leads: our best LPVO guide covers value and budget LPVOs, and our Primary Arms SLx 1-6x24 review covers the maker's value-tier 1-6x.
• Comparing short 1-8x scopes? Our compact LPVO guide lines up lengths and weights, and our Nightforce NX8 guide covers another compact 1-8x24.
