LBE Unlimited AR Pistol Buffer Tube Kit

The LBE Unlimited AR Pistol Buffer Tube Kit comes with everything to finish the recoil system for your AR-15 pistol. The kit includes a mil-spec style carbine spring and 3 oz. buffer weight, as well as castle nut, end plate, and buffer tube with foam sleeve. If you’re starting new, or retrofitting your AR pistol, this whole kit is a great value, and will keep your favorite build in compliance as a pistol.

The included featureless buffer tube cannot accept a stock or brace. To aid your rifle’s stability, we recommend a Magpul MS4 Sling in single-point configuration. Or the single-point sling of your choice. This will let you attach the sling to the rear end plate, and pull the sling taut for added stability.
