Everything is on its way. Tromix upper. Bear creek 16” Barrel. Tromix bolt for the aero bcg. I have a mega lower for it all of it to attach to.
Does anyone know where to find 458 ammo in stock?
I know building the 458 socom uses same mags, lower. I know the upper has to be widened so that means different upper, barrel and bolt carrier? Am I right on that?
Is it better in short barrel or long? 10.5 or 16 or 18?
