9mm (colt) style bolt carrier group. rdprecisionazllc works with glock and surplus 9mm magazines - R&D Precision Full Auto BCG

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 9x19 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.
