Review: Deadfoot Arms AR Folding Stock Adapter

November 26, 2019 by David Kenik 2 Comments

Deadfoot Arms offers a folding stock adapter for the AR-15 platform that allows the stock to be folded to the side, yet the rifle remains fully functional. In fact, entire magazines can be fired while the stock is folded. The ability to fold the stock enables the rifle to be stored and transported in a small case. The compact form makes it especially suitable for service as a trunk gun. The ability to shoot while folded is valuable when time is critical and too limited to unfold the stock in an emergency.

To fold the stock, simply press the button underneath the hinge and swing the stock to the side.

Unlike the traditional, AR-15 carbine buffer tube that measures 7.25 inches long, the Deadfoot Arms’ system only extends 2.5 inches beyond the upper receiver. Deadfoot accomplished this by replacing the AR’s standard bolt carrier group and buffer system with a shortened version that it designs and manufactures, called the Modified Cycle System (MCS.) The MSC consists of Deadfoot Arm’s M-16-style Bolt Carrier Group, short buffer tube, plunger, endcap, a buffer spring and choice of two recoil springs. The Deadfoot Arms bolt carrier measures 5 1/4 inches long, compared to the traditional, AR carrier which measures 6 5/8 inches. It is coated in TB-41 ION Bond DLC (Diamond Like Coating) which is a very durable coating, that is highly resistant to corrosion.

The system includes two, colored, recoil springs. The blue spring is standard strength and the red spring is light strength for use with low-power rounds such as subsonic offerings. A black spring is available for ARs chambered in 9mm NATO. The first step in the installation process is to thread the hinge system with the short buffer tube to the lower receiver. Then attach your choice of stock to the hinge system. The buffer spring is placed over the plunger and inserted through the hinge system into the BCG. The recoil spring fits inside the plunger and is held in place by screwing on the endcap. While is seems complicated, once you do it the first time it becomes quite simple.

To fold the stock, simply press the button underneath the hinge and swing the stock to the side. Systems are available to fold to either side. While folded, the stock is held by friction so there is no locking mechanism to hold it in place. Just swing the stock to the standard position until it clicks in place, and fire when ready. Due to the spring and plunger design, separating the receivers equipped with a Deadfoot Arms Folding Stock Adapter is different than the standard AR-15’s manual of arms. Before separating the upper, the adapter’s endcap must be unscrewed and removed which releases the plunger, recoil spring and buffer spring. While different than the standard AR, the Deadfoot Arms Folding Stock Adapter is very simple and fast.

Once installed, the system acts and shoots like any other AR-15. If you are looking to store and transport your rifle in an extra short case, the Deadfoot Arms’ AR Folding Stock Adapter is just what you are seeking.

    What does it cost? ( i.e.., in comparison to a sliding brace, that I can already use as a stock, that collapses to a very short length for transport or use as an A%-15 pistol ).

    Cute, but not for $495. Besided won’t work on my left handed AR
