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 for sure. R&D also has all the parts available for replacement if needed here at OpticsPlanet. Thank you R&D Precision for your help with my machine gun rental business!

Do not buy this junk. I took a chance buying this because it was a cheap. $97 down the drain. Just buy a kaw valley 9mm bcg. The extractor and bolt head were mishaped. It gave me numerous feeding issues. I thought it was the magazines

First off the product description here at OP needs work, I hope they change it soon. I contacted R&D Precision for more info prior to purchase and the owner replied within a day and told me some of what is written below. Some of this review comes from my own thoughts and experience with their product. The extractor is smaller than the standard M16 style extractor used by most companies for their blowback bolts. The smaller R&D extractor is inspired by the original Colt 9mm design and allows better support of the 45 auto cartridge as some of the upper bolt face rim doesn’t have to be removed. With the 45 ACP bolt face cut, the bottom rim is removed for better feeding with the Glock 21 mags. This is the same design as the 45 ACP BCG’s made by other brands and makes the upper rim area important in my opinion as there is not a lot of it to support the cartridge. The R&D 45 BCG at 14.6 oz, is about an ounce lighter than another popular 45 specific BCG. As long as an 11oz PCC specific buffer is used the small loss of bolt weight isn’t a deal breaker. My current setup works best with a standard carbine flat wire spring and the 11oz buffer. Heavy rate buffer springs that are popular in some PCC AR’s caused intermittent problems for me. This isn’t the BCG’s fault, it works efficiently with the proper weight buffer and a standard strength spring.

It is truest 9mm bolt carrier group to original successful Colt style 9mm Pistol Caliber Carbine that took the old stick style 9mm colt magazines.This Does work with pcc builds with Glock 19/17/18/34 any “Glock” style 9mm magazine, as well.It is blow back and black nitride coated. The extractor is like a (1911 extractor) so it is internal in the breech face. You can purchase those “colt-style 9mm pcc extractors here or rainier arms. The firing pin is “colt” style and is free floating for safety that too can be bought here or rainier arms. It is a good idea just to throw in your spare parts bin.Tail weight is semi -permanent. You won’t ever need to mess with it. This RDPrecisionAZllc is perfect for 9mm. this RDPrecisionAZllc 9mm bolt carrier group has a good weight in it and in combination you will need a 9mm spacer in the buffer tube and a standard ar15 3oz buffer minimum. An H3 or a 5.8oz buffer is Optimum.An extended 9mm pcc buffer (without a pcc buffer spacer) is best.It is ramped in the bottom to pick up the 9×19 round from the magazine and you will need a (non-ramped) 9mm barrel.The hammer cut out in the middle of the 9mm bolt carrier group is for standard milspec style ar15 hammers. It will obviously, fit most 1 stage or two-stage triggers be it regular or drop in triggers.Bad: It may not work with binary trigger setups because of hammers and the disconnector mechanisms. Too narrow of cut out.
