Colt





STAG/early S&W (very weak, but better than none, before using I would redo it)





Bushmaster (non existent staking, before using I would stake this)





Rock River Arms (they don't stake they blue Loc-Tite. I would heat and remove this stock, clean off the Loc-Tite reassemble and then torque and stake)





The gotm4 (this is a VLTOR complete stock assy on a Colt 6721 lower)
