I have these remaining A2 parts from a build I nearly finished, but then decided to go with an A5/STR stock set-up. The extension, buffer, and grip have been installed on a lower that only saw the inside of my safe and a couple trips to the range as host for my dedicated .22 upper. In other words, they are in excellent / like new shape. The receiver extension and buffer are from either PSA or BCM (can’t recall which, I’ve head them for about 2 years), and the Colt pistol grip was recently bought from Brownells (part # 160-308-150WB ). IMO, the Colt A2 grip feels is one of those “Colt small parts” that really are heads and shoulders above others.
