I’ve got a 9mm carbine with the SBA4 brace installed on it. Since conversion to SBR’s has gotten easier, I’d like to swap the brace out for a buttstock. Did the original Colt SMG’s have CAR15 stocks or would an M4 stock work? Also, would I need another buffer tube or would another butt stock fit on the one from SB Tactical? Here’s a photo of what I’m working with. Attached File |

Awesome! Looks better than the CAR15, imo, so I’m glad it should fit. |
