MAC-10 Stock Adapter

Features

1. AR-15 Stock Compatibility — Accepts any standard AR-15 buttstock, letting you swap the original wire stock for a far more rigid shouldering platform.
2. Direct Bolt-On Fit — Mounts to the existing factory holes on the rear of the MAC-10 receiver — no welding, drilling, or permanent modification required.
3. Rock-Solid Mounting Platform — Replaces the flimsy OEM wire stock with a tight, wobble-free interface that holds zero under sustained fire.
4. Improved Accuracy and Control — A proper fixed shoulder point dramatically tightens shot groups and tames the MAC-10's notorious muzzle climb.
5. Slow-Fire Conversion Ready — Pairs well with slow-fire builds where a stable, full-length stock is essential for accurate semi-auto work.
6. Steel Construction — Built from steel for the durability needed to handle the MAC-10's heavy bolt and high cyclic rate.
7. MAC-10 .45 ACP and 9mm Compatible — Fits both .45 ACP and 9mm MAC-10 SMG variants using the standard rear stock mounting pattern.
8. Opens Up Stock Options — Run a fixed A2, collapsible six-position carbine stock, PRS, or any other AR-pattern buttstock on your MAC.
