This guide details the installation and testing of the Dead Foot Arms underfolding stock system on an AR-15 platform, specifically demonstrated on a Palmetto State Armory KS-47. The video highlights the process of replacing the standard buffer tube with a proprietary shortened system to enable AK-style underfolding capability. It also covers crucial range testing, revealing that while the system allows for firing with the stock folded, it can lead to cycling failures due to port cover interference, making it impractical for folded fire. The expert instruction emphasizes understanding the mechanical differences and potential limitations of such modifications.

Quick Summary

Firing an AR-15 with an underfolding stock in the folded position can cause cycling failures due to the port cover's interference with the bolt carrier. The Dead Foot Arms system adapts AR-15s for AK-style folding using a shortened buffer tube, but practical use requires the stock to be deployed for reliable operation.

Frequently Asked Questions

What is the main challenge when firing an AR-15 with an underfolding stock like the Dead Foot Arms system?

The primary challenge is potential cycling failure. When the stock is folded, the AR-15's upper receiver port cover can interfere with the bolt carrier's rearward travel, preventing the rifle from properly ejecting the spent casing and chambering a new round.

How does the Dead Foot Arms underfolding stock adapt the AR-15 platform for AK-style folding?

It achieves this by replacing the standard AR-15 buffer tube with a shortened, proprietary system. This allows an AK-style underfolding stock mechanism to be mounted directly to the AR-15 lower receiver, mimicking the folding capability of some AK variants.

Is it practical to fire a 7.62x39mm AR-15 with an underfolding stock in the folded position?

Generally, no. While the stock can be folded for a more compact profile, attempting to fire the rifle in this configuration often leads to malfunctions. It's best to deploy the stock before firing for reliable operation.

What components are crucial for the Dead Foot Arms underfolding system to function on an AR-15?

Key components include the shortened proprietary buffer tube, specialized recoil springs, and potentially a modified bolt carrier group. These parts work together to manage the cycling impulse within the confined space created by the folding stock mechanism.
