    Commercial Lower/Stock Availability.

    Quick question- Got a commercial spec Bushmaster lower(.223/5.56) laying around that I want to mate up w/ a 20’ barreled upper and slap maybe a Vortex on it for the Mrs to start doing longer range work. I’d like to put a simple old-school USGI type rigid stock on it but I can’t seem to find any designated for commercial spec receiver extensions. Are these even made or am I stuck w/ commercial spec carbine style buffers tubes for my stock choices?

    Thanks in advance-YZ

    Kind of depends if you want a Fixed A-1 stock which are shorter than a fixed A-2 stock. The easiest route would be to buy a complete A-2 stock like the one from RRA or White Oak Armory.

    Brownell’s sell fixed A-1 stocks and you can call Brownell’s technical to see if your commercial buffer tube will work with a particular stock.

    I checked but Brownell’s was out of stock but Midway has a couple of options. I’m sure other vendors still sell A-1 and A-2 fixed stocks, if nothing else for people wanting to build a retro rifle like an M-16 A1 or A4.

    Unlike carbine type receiver extensions where there is a military or commercial receiver extension it is my understanding that all of the fixed stock rifle receiver extensions have the same dimensions.

    There are material differences though, but probably not that important. I know Colt used/uses a rifle extension that is some type of forging rather than an extrusion. They probably did that to make it less likely to break when buttstroking a foe.

    Colt rifle extensions available at Brownells.

    Cheers guys. Sorry about the delayed response... holidays. If I had to guess an A1 would be a better LOP. She rides her carbine stock a knotch or 2 forward. We’ll see what’s available. I got some questions in w/ the customer service depts of your suggestions. I’ll keep you posted.

    Cheers again, much appreciated.

    Update- Brownells finally got back to me. They say that extension will in fact fit both commercial spec and military receivers. So I guess I'm good for the fixed stock.
