Trijicon Credo review: the 1-8x28 is a tough, clear FFP LPVO that asks you to carry the weight

By the OpticVerdict Editorial Team.
Research-based review · Updated 2026-09-30

How we reviewed it: a research-based review built from the retailer's specification tables for four Credo listings, every owner review those listings show (15 for the 1-8x28, 15 for the Credo 1-6x24, 12 for the Credo HX 1-6x24 and 10 for the 3-9x40), and Trijicon's own product and warranty pages for the manufacturer figures. Where the retailer table and Trijicon disagree, we print Trijicon's figure. Third-party research leads we could not confirm on Trijicon's site, including awards and country of manufacture, were left out. We have not bench-tested these scopes; the score is our editorial opinion and owner ratings are shown attributed to their source. See how we evaluate.

What the Credo 1-8x28 is

The Credo is a Trijicon riflescope family, and the 1-8x28 is the largest of the three LPVOs on this page. Trijicon describes it as rapid target engagement and long-range precision from the same riflescope, calls it a favorite among competitive shooters and tactical users, and pairs it with a 28mm objective lens for a generous exit pupil and low-light performance. It lists the exit pupil as 11.68 to 3.56 mm, which matches the arithmetic: 28 mm divided by 8 is 3.5 mm.

The reticle is an MRAD Segmented Circle in the first focal plane, so the marks keep their value at every magnification; our FFP vs SFP guide explains why that matters for holdovers. The illumination runs red or green from one CR2032, with five settings of each color and an off position between each setting, and Trijicon lists 39 hours of battery life on red and 94 hours on green. The adjusters click in 0.1 MRAD with 29.1 MRAD of total travel. Trijicon's feature list adds a repositionable magnification lever, an easy-focus eyepiece, fully multi-coated broadband glass and a ruggedized design tested to military standards and protocols. Trijicon's site also lists Coyote Brown versions of the 1-8x28 with an MRAD or MOA Segmented Circle; the row we price is the Matte Black MRAD version.

Why reviewers rate it: glass, the 1x view and toughness

Of the 15 reviews on the retailer's page, all of which we could read, 11 are five stars, three are four stars and one is three stars. Glass or clarity is the praise that repeats most: six of the 15 reviews we could read name it, from “great glass” in a pros list to excellent clarity. Reviewers also single out the 1x view, the eye relief and eye box, and the turrets. One reviewer, who titles the review around 3 Gun, had previously used a Vortex Razor HD 1-6 and then a Nightforce NX8 1-8.

“great illumination even during mid-day in full sun. The clarity at 1x is great”

Durability comes up as well: one reviewer who owns both the Credo 1-6 and 1-8 lists “Bomb Proof” among the pros. The single three-star review is about condition on arrival, with scuffs on the tube and dust on both lenses, not about how the scope performs.

The honest catches: weight, a thick ring at 8x and the brightness debate

Weight and size. At 25.6 oz, 10.8 inches long and 3.2 inches wide on Trijicon's spec page, this is not a light LPVO. Five of the 15 reviews we could read list weight or size as a con, including the reviewer who calls it bomb proof.

“own the credo 1-6 and 1-8's. Quality is never an issue with Trijicon, heavy yes”

Daylight brightness depends on who you ask. Two reviewers describe the illumination as bright in daylight, one of them in full midday sun, and two others say it is not daylight bright but still visible or crisp. If you want red-dot brightness at 1x, weigh that split before you buy.

“It is not daylight bright like a red dot but it is definitely visible”

The ring grows at 8x. Because the reticle is in the first focal plane, it scales with the image. One four-star reviewer lists “Donut is too thick at 8X” as a con and says it is “so big and bold at 8X that scanning for targets down range is somewhat hindered”. The same reviewer lists turrets that lift easily as a con.

Head position. Two reviewers find the eye position fussy: one says it takes a few seconds to get it adjusted to the eye, another calls the eye relief “kind of fussy”, while two others praise the eye relief or eye box.

Zero stop. One reviewer lists no zero stop as a con. Trijicon's page for this model describes the adjusters as exposed and locking; if a zero stop matters to you, confirm it with Trijicon before you buy.

Trade-offs, plainly

• 25.6 oz on a 34mm tube: five of 15 reviews call it heavy or big, so it suits a rifle you do not carry all day.
• Daylight brightness splits reviewers two and two; do not buy it expecting a red dot's brightness at 1x.
• The first focal plane ring gets big at 8x; one reviewer says it gets in the way of scanning.
• Eye position can feel fussy to some reviewers, while others praise the eye box.
• A 34mm tube needs 34mm rings or a 34mm mount; see our scope rings guide and how to mount a rifle scope.

Credo vs Credo HX: what is actually different

The two names are easy to mix up because both lines sell a 1-6x24 on a 30mm tube. On Trijicon's spec pages for the two rows we price, every optical, size, weight, adjustment and illumination figure is identical; what changes is the job each line is designed for, the finish and the reticle choices. Trijicon designs the Credo 1-6x24 “with 3-gunners and law enforcement in mind” and the Credo HX 1-6x24 for hunting hog, varmint and whitetail.

How to choose between them. Pick by reticle, not by name. The HX's PowerDot BDC Hunter Holds is sold in .223 and .308 versions, so a hunter can match the holds to the cartridge; the Credo's SFP BDC is marked for .223/55gr and its FFP option is in MRAD, which suits a shooter who works in mils. On the owner record, HX reviewers are the happier group on brightness: five of the 12 reviews we could read praise it, and two of them say they have the red dot version. On the Credo 1-6x24 listing, reviewers are split. The HX line listing also sells first focal plane MOA Segmented Circle rows at their own prices. For the mils against MOA question, see our MOA vs MRAD guide.

Which configuration: the four Credo listings

OpticsPlanet sells the Credo on separate listings, each with its own part numbers. We price the row each listing shows first, and describe each one only from its own listing and Trijicon's page for that row.

Credo 1-6x24, SFP red BDC Segmented Circle

The Credo 1-6x24 (CR624-C-2900015) is the lighter Credo for an AR-15 or patrol rifle: 18.9 oz per Trijicon, with the second focal plane red BDC Segmented Circle marked for .223/55gr and 1/4 MOA clicks. Its listing also sells a green BDC row and red or green first focal plane MRAD rows at their own prices, and its 15 reviews are shared across all four rows. Reviewers praise the glass; one compares it with a Vortex Razor HD and another with a Primary Arms Platinum 1-8. Brightness is the argument: five of the 15 reviews we could read criticise daytime brightness, from “not the brightest” to a two-star review that calls it terrible at the highest setting in daylight, while three call it daylight bright, including one who runs the same SFP red BDC we price. One three-star reviewer reports a flickering reticle on the two units they received; that is one owner's report, not a pattern in the record.

“the SFP red BDC is daylight bright”

“The red dot does slightly wash out on light colors on a bright day”

Evan P (CA), Verified Owner, Credo 1-6x SFP BDC, via OpticsPlanet

Credo HX 1-6x24, SFP red PowerDot BDC Hunter Holds .308

The Credo HX 1-6x24 (CRHX624-C-2900019) is the hunting version. The listing's web address mentions .223, but the row it shows first, and the one we price, is the red PowerDot BDC Hunter Holds for .308; the listing also sells .223 and green versions and two first focal plane MOA rows at their own prices. Trijicon lists 18.9 oz; the retailer table says 18.3 oz, and we go with the maker. Ten of its 12 reviews are five stars. Reviewers praise the glass, the weight and the bright center dot; one compares the image with a Vortex Razor LHT. The cons are price (two reviewers), slightly heavy (one), a reviewer who lists QC issues as a con, and a four-star reviewer who says the reticle is the only thing holding it back. One owner who chose the first focal plane green version found the center hard to see at low magnification.

“on setting 10 for illumination it is definitely daylight bright. The scope i purchased was the hx 1-6 with red dot.”

Pat (FL), via OpticsPlanet

“When it is not zoomed in you cannot see the center illuminated cross hair very well even at full power.”

Nick (MS), Verified Owner, FFP green version, via OpticsPlanet

Credo 3-9x40, green MIL-Square Crosshair

The Credo 3-9x40 (CR940-C-2900042) is not an LPVO: it starts at 3x, rides on a 1 inch tube and weighs 17.02 oz per Trijicon. The row we price has a green MIL-Square Crosshair in the second focal plane with 0.1 MIL clicks and 12 MIL of total travel, 11 LED settings and a listed battery life of 198 hours. The listing also sells red MIL-Square, MOA Precision Hunter and Standard Duplex rows at their own prices. All 10 reviews are five stars and are shared across the rows; reviewers praise clarity, the eye relief and the lighted reticle, and the only negatives they mention are about price. One uses it on an M40 replica for a CMP sniper match. The trade-offs come from the spec, not the reviews: 3x is too much for close, fast shots, and the retailer table lists fixed parallax.

“The illuminated crosshair shows up great on a black target.”

Key specifications: Credo 1-8x28 (CR828-C-2900032)

Figures are from Trijicon's product page for CR828-C-2900032 and match the retailer's specification table, except where marked "retailer table" (the Trijicon product page we read does not list those figures). No award is claimed for the models on this page.

Should you buy it, and what else to consider

• Buy the Credo 1-8x28 if you shoot 3 Gun or run a duty-style rifle, want an FFP MRAD reticle with 8x on top, and accept the weight.
• Buy the Credo 1-6x24 if you want the Credo in a lighter 30mm body for an AR-15, with a .223 BDC or an MRAD option.
• Buy the Credo HX 1-6x24 if you hunt hogs, varmints or deer at close to moderate range and want a red center dot with holds matched to .223 or .308.
• Buy the Credo 3-9x40 if you want a traditional hunting magnification range with an illuminated reticle on a 1 inch tube.
