The Choate Tool stock is very lightweight compared to the ATI Monte Carlo and I prefer it. The old ATI folder is funky and the hinge is the weak point. I don’t think any have a bayonet cut. I don’t remember and have since gone back to wood. Lucky Shot Wood Stocks on Etsy or Ebay are bitchin’ and priced nice for some sweet USA made 922r compliance on 2 parts.
I haven’t used the Tapcos, FAB, RamLines or the Promag Archangel.
