AR15 Pro - Defensive Carbine: New Lower for my Superlight AR15
I did look at those, too. Only prob, none of the local gunnies stock them, and didn't want to pay transfer fees. Plus I had a few lowers and uppers on hand, that were kind of 'orphaned', just sitting and waiting to be fondled. She likes the A1/A2 uppers w/ built in handle, because the sight is built in and less to go wrong with them. And her eyes are still better than most, so she like the iron sights. Props to her, mine used to be 20/15, but the mileage has made those numbers not so good anymore. But I can still keep them in the 10 ring, so not complaining. She shoots the lights out anytime, anywhere, with pistol, rifle, or shotty, so I'll put together what she is comfortable with.
But the Cav Arms lower is a really good idea for those trying to keep it lightweight.
