This guide details a field-expedient modification to fix a wobbly Tapco folding stock on an Arsenal SGL21 rifle using JB Weld. The process involves sanding contact points and applying JB Weld to create a solid, fixed stock, thereby increasing the length of pull for improved shooting ergonomics, particularly in prone positions. This modification is presented as a solution for shooters experiencing discomfort or instability with standard AK furniture.

Quick Summary

A common issue with Tapco folding stocks on Arsenal SGL21 rifles is excessive wiggle. This can be resolved with a field-expedient JB Weld modification. By sanding contact points and applying JB Weld, the stock becomes fixed, increasing the length of pull for improved ergonomics, particularly in prone shooting positions.

Frequently Asked Questions

How can a wobbly Tapco folding stock on an Arsenal SGL21 be fixed?

A wobbly Tapco folding stock on an Arsenal SGL21 can be fixed using JB Weld. The process involves sanding the contact surfaces of the stock and receiver, applying JB Weld, and reattaching the stock in a fixed position. This creates a solid stock and increases the length of pull.

What are the benefits of modifying an Arsenal SGL21 stock with JB Weld?

Modifying the stock with JB Weld creates a fixed stock with a longer length of pull, which can significantly improve shooting ergonomics, especially in prone positions. This helps prevent the rifle from hitting the shooter's collar bone and allows for a more stable shooting platform.

Why is the factory AK rail preferred over the Midwest Industries front rail for an Arsenal SGL21?

The factory AK rail is preferred because it doesn't clamp onto the barrel, allowing the barrel's harmonics to function as intended. The Midwest Industries rail, which clamps to the barrel, is avoided to keep the barrel unencumbered and potentially improve shooting accuracy.

What is the recommended stock length for an AK platform with optics?

For AK platforms intended to be used with optics, the NATO length stock is recommended. This is because the Warsaw length stock can place the optic too close to the shooter's face, causing discomfort and potentially affecting shooting posture.
