I bought this to use with a FRT Super safety. Works great with no mods.

After about an hour of trying to figure out why my AR-45 couldn't shoot without a malfunction, we learned that the extractor simply is not holding onto the round well enough to reach the ejector. It falls out on top of the round in the mag, then gives the gun a pretty serious jam.

The R&D .45 bolt has functioned flawlessly in my AR 45 without a hiccup, but I have only run a few mags through so far. I was skeptical at first because of the low price and bought a Kaw Valley bolt as well- just in case the R&D wasn’t up to the task, but I think the KV will be used for a backup and the R&D will be the main bolt for my Foxtrot Mike AR 45 pistol. The real test will be seeing how it holds up after a few thousand rounds.

Works great with a standard Bushmaster T2 buffer spring system and Mean Arms Exomags. No feed or jamming issues. I'll be buying another one soon.

I recently built a budget AR-9 and I decided to check my split times with it and they weren’t as fast as I liked so I modified the existing bolt but then needed to shout hotter ammo to maintain reliability. This bolt is what I should of started with, not only did improve my speed and accuracy but it runs with any ammunition

I like this product. made well and at a price i can afford. thank you for all your effort in making this right.

Works well with ets glock mags not so much with stock glock mags

I like the first one I bought so much I bought another works great for the price you can't go wrong.

Bolt works great, for the price I paid OI could not ask for more

I have had problems with other 40 S&W BCG on full auto. My last set was having firings out of battery and when doing so, the paddle type extractor would break. Furthermore, nobody who sold the other types of BCG could offer or help to provide replacement extractors as the bolt face and extractor were of a proprietary design. Unfortunately, I was left with dead BCG's (due to missing extractor), no way to fix them and an upper receiver that can't work without a BCG. Never mind the out of battery firings. I searched for some time for other 40 S&W BCG's with a different design. I contacted some manufacturers. Some responded, some didn't. Finally I contacted R&D Precision. They called me back and we had a long talk about my problems. They explained that their BCG design is different and should work better. Upon receiving the BCG, I examined it. It almost fully encases the much smaller extractor length wise and does not serve as a portion of the bolt face as the other BCG designs did. The R&D Precision bolt face is all part of the bolt with the extractor merely being a separate piece inside of the bolt face. I fired multiple mags on full auto, various lengths of bursts and switching back and forth to semi using the same previous upper receiver and ammo. When switching mags, I would release the bolt catch and let the BCG ram forward and rock and roll. I had no issues at all. That tells me the issues were the other BCG designs for sure. If you are going full auto, you need these BCG ...
