It's a 22AR. Cav Arms MKII lower from GWACS Armory, GWACS Armory sling, TACCOM 22 16" barrel, TACCOM enhanced stainless bolt system, standard AR upper with forward assist and dust cover, 12" Midwest Industries Gen II free float rail, Midwest Industries splp low pro buis, standard A2 comp, carbine buffer, standard charging handle, Blackdog Machine mags. It's basically an AR minus a gas block and tube. Change the barrel and bcg and add the appropriate gas system and make it whatever you want. I built it over about a years time and the parts added up. Suffice it to say you could probably build two cheapo 5.56 Palmetto kits today for what I have in it if that tells you anything. Stupid, I know.
I'd be glad to IM a couple of pics. I can't post pics and don't feel like messing with a photobucket or photo hosting site account.
