Most Helpful Positive Review Primary Arms Anti-Reflective Device
Great anti-reflective device, it does what it is suppose to do. Does not interfere with view looking through prism optic. I had no problem screwing it onto the optic. I liked it so much I bought the other one for my 1x prism optic.

Cheaper and way better than Tenebrex

by RedRiot, Verified Owner from AR, United States Written on December 17, 2024
Was a Trijicon loyalist for years until I got hooked on the ACSS reticle in my 4X ACOG and then started buying PA simply because of the ACSS throughout their lineup. The plastic Tenebrex killflashes are $80, and are just so-so quality and the ACOG model has a pathetic mounting "solution" that screams afterthought. The MRO models at least clamp on whereas the ACOG one secures with and elastic o-ring that never really holds it in place confidently. When I got my new 5X and 3X micro prism PA sights I immediately popped for the PA brand killflashes and was a)blown away by the quality b)pleased with the secure, thread-in mounting c) impressed with the aluminum construction throughout d) confident in the way PA obviously designed these parts as a system from the ground up. Honestly, Trijicon is resting on their reputation at this point. I'm PA all the way.
Pros:
  • secure mounting
  • Inexpensive yet high quality
  • low prifile
  • Well though out and properly engineered
Cons:
  • None
Best Used for:
  • The designated application

SLx Anti-Reflection Cover

by Gunfighterman, Verified Owner from PA, United States Written on November 3, 2024
It works. What more can I say other than when looking thru the optic you hardly notice the honeycomb. Oh, one thing to be careful of though. It has a fairly fine thread so it's easy to cross thread it.

A Must-have for SLx Prism

by Mongo65, Verified Owner from NC, United States Written on October 31, 2024
A perfect fit. This allowed me to do away with the cumbersome bikini cover and still provide protection to the objective end. Completely invisible, unaffected view.

Primary Arms ARD

This Killflash for the PA 3x Micro Prism is an essential piece of equipment. It fits perfectly and knocks out the potential glare off the occular lens that would be giving away your position. It makes an already awesome optic even better! A must buy!

fits on sight

by Uncle Dave, Verified Owner from CA, United States Written on January 2, 2024
I had forgotten to add this item when I purchased a 3x microprism sight. The device easily fits onto sight. I haven't checked if it is functional and should be better in not reflecting the sight lens since it does place the lens further back.

Exactly as expected

by Jon, Verified Owner from OH, United States Written on December 31, 2023
The threads are very fine so clean both the anti-reflection device and your optic before installation. Even the tiniest particles of dirt and dust will cause it to not thread on smoothly. I applied a TINY amount of anti-seize and locked it down hand tight, and it hasn't loosened over a hundred rounds later. The finish is a perfect match for the optic and the depth seems more than sufficient to block inbound and outbound glare. My only complaint is that if it had a bezel at the end the same diameter as the optic's objective housing then the silicone lens cover would fit much better. It has enough stretch to cover the extra distance but the smaller diameter of the anti-reflection device causes a less-than-stellar fit.
Pros:
  • Works as intended
  • Perfect fit and function
  • Price matches quality
  • Toolless installation
Cons:
  • Poor lens cover fit
  • Extremely fine threads
Would recommend: Yes
