T or F: Ruger's casting division makes the upper & lower receivers (as they do for many AR makers)?
I've built up two on S&W lowers to date, and have no problems as they are MIL-spec and heat-treated to 7075 (complete, not just the ring and hinge areas). One nice thing - the lowers are not caliber-specific, enabling them to be built into chamberings other than 5.56.
Decent AR copies. And specified in H.R. 45 for it's owners to be subject to government registration & licensing.
