i use these on all my builds by MatthewOO0029, Verified Owner, April 4, 2020
I was find myself always buying these and the rest of the armaspec spring/detents. I will just buy their springs kits now that I realize I have been paying more than I could. I highly recommend these as they are super high quality.

Smooth action by Smoothass Builder, March 21, 2020
The Armaspec Bolt Catch Detent set is beautiful to look at but that won’t really matter once it’s installed and you never see it again. However, it’s action is very smooth. Real quality. I will purchase again for my next build.

Good product by Outsiders, March 29, 2018
Small parts but still critical to the operation of the firearm. Fit and finish are great and no issues with function. The stainless detent is very smooth with no burrs or machining marks. I recommend this part and will be using on future projects.

It does it’s job by Dmac, March 8, 2022
Not much to say, it’s a stainless version of a bolt catch detent. Was the one spare part I didn’t have when doing a spare part build. Also good if you loose one. The stainless is easier to spot on the floor. Does it’s job
