10/22 Magazine Extension

Upgrade your 10/22 rotary magazines with our rugged polymer extensions. These extensions attach securely with no glue, no epoxy, no permanent mods, and lock up tight with zero wobble. A built-in compartment lets you add weights to ensure your magazines will drop free. The extension increases length by 33mm (1.3") and includes a flared bottom for an enhanced grip.

Installation
Hold the extension against the magazine and install two screws in opposite corners, alternating screwing them in until they are hand tight.
Then install the other two screws hand tight, it is very important to not over tighten them.
