Luth Ar 223 Rfl/fxd Bfr Tube Assy

The Luth-AR 223 Rifle Fixed Buffer Tube Assembly is a complete, ready-to-install component package designed specifically for AR-15 platforms that utilize fixed buttstocks. This assembly is engineered to deliver the correct spring rate and buffer weight tuning for .223 Remington and 5.56mm NATO cartridges, ensuring reliable cycling and consistent recoil impulse.

The assembly includes three core components: an A2 fixed buttstock-compatible buffer tube, a standard .223 rifle recoil spring, and a rifle-class buffer body. This combination maintains the necessary relationship between spring preload and buffer mass for proper bolt carrier group cycling, all manufactured to AR-15 mil-spec tolerances for durability and reliability.

This buffer tube assembly is ideal for operators, shooters, and armorers who are building or maintaining .223/5.56 rifles that require a fixed stock configuration. It provides a solid foundation for reliable operation, making it a suitable choice for those looking to enhance their AR-15's performance with predictable recoil management and consistent bolt carrier velocity.
