Trijicon RCR review: the enclosed RMR, with two catches

By the OpticVerdict Editorial Team.
Research-based review · Updated 2026-09-29

How we reviewed it: a research-based review built from Trijicon's own product page and announcements, the retailer listing, and the full owner-review record we could read, lowest rating first. Where the retailer's specification table disagrees with Trijicon, we publish Trijicon's figure and say so. We have not bench-tested this unit ourselves; the score is our editorial opinion and owner ratings are shown attributed to their source. See how we evaluate.

What it is

Trijicon describes the RCR as "the same unique patented housing shape of the RMR now in a closed emitter version", and as an optic built to meet the demanding standards of military and law enforcement use. The practical point is compatibility. A closed emitter normally means a new footprint or an adapter plate, but the RCR uses the RMR bolt pattern with no additional plates and sits at the same deck height as the RMR. It does that with patented capstan screws, which Trijicon says prevent over torque, cross threading and stripping. The box carries two #6-32 short, two #6-32 medium and two #6-40 long screws, the long pair for FN platforms, plus a torque guide and a Loctite capsule.

The rest of the specification is duty-grade. It runs a 3.25 MOA red dot with 10 brightness settings, three of them for night vision and one super bright, adjusts at 1 MOA per click with 150 MOA of total travel, and is rated from -40 to 140 F. Trijicon builds it at its headquarters in Wixom, Michigan.

A spec warning before you compare listings

At the time of writing, the OpticsPlanet specification table lists the RCR's emitter type as "Open" and its weight as 1.69 oz. Trijicon's own product page says closed emitter and 1.95 oz (55.28 g), and submersible to 66 ft (20 m). The retailer's own product description on the same page also calls it a closed-emitter optic, and so do the owners. Use Trijicon's numbers; this page does.

Why owners rate it: sealed, tough and easy to live with

Of the 29 reviews we could read on OpticsPlanet, 22 are five stars. The recurring praise is the enclosed emitter, the build and the battery. Several reviewers came from the RMR, and one calls the RCR worth the upgrade. One reports using it in rain and snow without trouble, and five single out the top-loading battery; an RMR owner explains why, being tired of pulling the optic off the slide to change the cell. Reviewers describe the dot as crisp and bright, and one found it cleaner than an old RMR with little tint to the glass. It turns up on a wide spread of guns in these reviews: a Glock 34, a milled Gen 5 Glock 45, a Staccato P on a Dawson plate, an FNX-45T, and a Beretta A300 Ultima Patrol shotgun.

“No bells and whistles, just a tough well made optic. Closed Emitter is the way to go. Had it out in rain and some snow and it is worry free.”

“I have many RMR but get tired of having to pull off the dot to put a new battery in. I love that this one does not have to be removed.”

Owners who weighed it against the Aimpoint ACRO mostly came down on the RCR's side: one titled a review "Better than the ACRO P-2", another called it much better and more durable, and one found it fits a Safariland 6360 holster where the ACRO did not. One reviewer who was torn between the two concluded you cannot go wrong with either.

The honest catches: height, screws and price

Owners find it sits tall. Trijicon keeps the RMR deck height so RMR-compatible iron sights can be used, but owners report the base crowding their irons. One reviewer on a SIG P320 M17 could barely see Trijicon suppressor height sights over the base, and another says suppressor height sights on a Shadow Systems pistol were useless without taller ones, adding that with an adapter plate it sits pretty high. If co-witness matters to you, check your sight height first.

The capstan screws limit some slides. The patented screws are the reason it fits an RMR cut, and the reason it does not fit everything. One owner reports it will not fit a ZEV slide or a Glock 19 ORCA slide because both use #4-40 threads, and that no fix was available at the time. Another wanted it on a Shalotek Warden P320 slide, mounted it on an FNX-45T instead, and says more screw options would have earned five stars. Trijicon lists a separate RCR mounting plate for Agency AOS and ZEV style cuts, so check your slide before you order.

“Great build quality awesome sight picture. Sucks it doesn't fit the ZEV slide or Glock 19 ORCA.”

A small number of optical and unit complaints. One reviewer reports a second, ghost red dot on the rear glass sitting below the real one, and found it disrupted a fast draw. Another reviewer's dot began fading about five months after purchase and then kept disappearing; eight days after the optic was sent in, Trijicon emailed that it would send a replacement RCR at no charge. One reviewer felt it was susceptible to parallax in unsupported shooting and found the adjusters hard to reach near the glass, while allowing that technique might be the cause. One buyer says the unit arrived used and worn, and another notes the optic came loose in its box with no wrapping; both are accounts of what was received, not findings we could check.

Price. Four of the 29 reviews we could read name cost as a drawback, including owners who rated it five stars. It is a premium-priced dot; the RMRcc and value enclosed dots cost less.

Trade-offs, plainly

• Sits tall, owners report: suppressor height iron sights can be crowded or hidden depending on the pistol.
• The included capstan screws are #6-32 and #6-40; one owner reports slides with #4-40 threads (ZEV and the Glock 19 ORCA) will not take them. Trijicon sells a separate RCR plate for Agency AOS and ZEV style cuts.
• One reviewer reports a ghost dot reflection on the rear glass.
• Premium price, with cost the most common reservation among otherwise happy owners.
• It is built on the RMR footprint, so a slide cut for a smaller carry footprint needs a different sight or an adapter plate.

Key specifications

Specifications are from Trijicon's product page for model RCR1-C-3300001 and its January 2024 award announcement, except the rows marked as the retailer's. On the listing: the same OpticsPlanet page also sells a kit that bundles the RCR with a Radian Weapons Guardian optic guard for MOS Glock pistols and back-up iron sights; it costs more and is not the unit priced above. The 4.4/5 rating is the retailer's figure across 31 reviews; the review page displayed 29 of them, so every count on this page is out of those 29.

Should you buy it, and what else to consider

• Buy it if your pistol already has a standard RMR cut, you want a sealed emitter for carry or duty, and you run tall enough irons or none at all.
• Want the open-emitter original or a smaller carry dot? Our Trijicon RMRcc review covers Trijicon's slimmer carry sight, and Trijicon RMR vs SRO compares the open RMR with the big-window SRO.
• Want the biggest window for competition? The Trijicon SRO is Trijicon's large-window open reflex.
• Want the rival enclosed duty dot? See our Aimpoint ACRO P-2 review, or the Holosun EPS Carry for an enclosed dot at far lower cost.
• Rifle or shotgun instead? Trijicon's enclosed rifle sight is the MRO HD.
