DFA Underfolder 4" Rifle Kit

Limited Edition product. Due to current world events, once this product sells out, there is no guarantee for a restock.

The DFA Underfolder 4" Rifle Stock utilizes our Modified Cycle System(MCS) and has a folded length of 3.9" 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 4" Stock utilizes the patented Dead Foot Arms LLC Modified Cycle System and uses your personal unmodified bcg. Rifle caliber BCGS need to be full auto and have an internal diameter of at least 0.62" to accept our plunger.

Will work with most 9mm BCGs. BCG needs to have an internal diameter of at least 0.62 inches in diameter and have a removable weight that doesn't change the length of the bolt. 9mm BCGs that have a removable weight that reduces the overall length of the bolt are not compatible. 

9mm- ***INTERNAL BCG WEIGHT MUST BE REMOVED PRIOR TO INSTALLATION. PLEASE READ INSTRUCTIONS THAT COMES WITH THE KIT. WARRANTY IS VOIDED IF DAMAGE OCCURS BECAUSE THE WEIGHT WAS NOT REMOVED PRIOR TO INSTALLATION.

System includes complete stock assembly, receiver extension collar, buffer tube, end cap, plunger/recoil springs and plunger. System weight, excluding BCG is 1 lb 11 oz. Underfolder will clear AR-15 magazines.

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