JE Machine Tech PS-BTA A1 Buffer Tube AR-15/AR-10 10" 6061-T6 Aluminum

The JE Machine Tech PS-BTA is an A1-length buffer tube purpose-built for AR-15 and AR-10 rifles. Machined from 6061-T6 aluminum and finished with a hard Type II anodized coating, this fixed-profile tube measures 10" long and weighs just 3.2 oz. The A1 length is the classic shorter profile originally designed for the M16A1/A2 fixed buttstock, making it the ideal choice for retro builds, A1/A2-style rifle restorations, and any platform running a traditional fixed stock.

Engineered to be drop-in compatible with both .223 and .308 buffer and spring assemblies, the PS-BTA works equally well on a standard AR-15 platform or a big-bore AR-10 build. The Type II hardcoat anodized surface shrugs off scratches and the rigors of regular range use, while the precision-machined interior ensures smooth buffer cycling and consistent lock-up with your fixed stock of choice.

Whether you're completing a retro A1-style rifle build, replacing a worn factory tube, or upgrading your AR-10's rear end, the JE Machine Tech PS-BTA delivers the strength, fit, and finish the platform demands from a quality aftermarket component.
