I never had any thoughts of wanting an AR pistol, but with all of the attention the brace rule litigation has brought about, I decided to build one. I procured an SB3 brace and I’ve decided to just stick with .556 NATO caliber (or .223 Wylde). So my questions are mostly, what barrel length, twist rate and are there any tricks or things I should know, or avoid, what works best. All input is welcomed.
Thanks
