It would work with a BCM lower from G&R Tactical or a Sons of Liberty Gunworks lower since those can be ordered without a stock. Sionics Weapon Systems also has a package they call the Gutless Wonder lower which has most of the annoying pins and detents installed but no stock, pistol grip, trigger guard or fire control group. Its listed at $150 on their site which I think is a fair price.
Im brainstorming a pistol build with the SBA3 right now and the rut Im stuck in is that the SBA3 comes with a receiver extension and so do all the preassembled or mostly preassembled lowers. I hate having excess parts that arent normal wear parts. If the brace didnt come with a receiver extension, Id order an SBA3 and the Sionics Gutless lower and be done with it.
Unless I decided to use a LAW folding stock adapter! Then a preinstalled receiver extension on a lower would be a nuisance. Too many options coupled with the fact that an AR pistol would just be a toy for me is whats stopping me from building one.
