Just out of curiousity, do you prefer using a pistol buffer tube and fixed LOP brace?
The SBA4 is adjustable and uses a standard milspec carbine tube.
The SBM4 is fixed and uses a pistol buffer tube.
I'm glad you got something out of this thread.
I usually just get reminded how stupidly arbitrary the current infringements really are...
Looks like I'm getting more from this thread with every post. As far as my preference goes, I'm working on determining that now. I've ignored anything having to do with AR pistols for years so am trying to catch up now. I wasn't familiar with the new SBA4 brace but I looked it up and it looks great, thanks. Does it stay within the 13.5" LOP limit when fully extended? I didn't see anything that addressed that.
Edited to add: I just found this online..."The SBA4 Brace will be 5-position adjustable but will maintain the ATF mandated length of pull to keep your AR pistol legal."
