Stag Arms Mil-Spec Receiver Extension Assembly - no buttstock

The Stag Arms Tactical Receiver Extension is the perfect mil-spec collapsible receiver extension for your Magpul CTR stock. We have personally tried these receiver extensions wiht the Magpul CTR and it is a 100% solid lock up. There is no movement.

This receiver extension also comes with a castle nut, endplate, CAR action spring, and Stag carbien buffer.

If purchased separately this package would be $59. You save $4!
