DFA Underfolder 2.5" Rifle Kit

The DFA Underfolder 2.5" Rifle Stock utilizes our Modified Cycle System (MCS) and has folded length of 2.5" off the back of the lower receiver.

The Underfolder utilizes an Original Hungarian AKM Underfolder Stock Assembly and locking mechanism, in *good* condition. The single push button allows the locking mechanism to release, adding to the security of the stock in the folded or deployed position. Parts have been previously fitted and may show slight signs of wear.

The Underfolder 2.5" Stock utilizes the patented Dead Foot Arms LLC Modified Cycle System and a shortened version of the M16A2 or 9mm Bolt Carrier Group which is included with this kit.

System includes complete stock assembly, receiver extension collar, buffer tube, end cap, recoil springs, plunger, rubber bumper for 9mm kits and MCS Style (shortened) M16A2 or 9MM bolt carrier group. System weight, excluding BCG is 1 lb 11 oz.

Please also choose the side you would like your push button installed on. This allows the Underfolder to deploy and fold.
