The Luth-AR 11.5" Lightweight Barrel With Front Sight Base is built for shooters who want a compact, dependable AR-15 upper without unnecessary bulk. This government profile 5.56mm barrel uses durable 4150 CMV steel and a manganese phosphate finish, providing a solid foundation for a hard-use carbine while the fixed front sight tower offers a familiar, reliable aiming reference.

With its 11.5" length and 1:7 twist rate, this barrel is well suited for training, general range use, and building a compact rifle or registered short-barreled rifle that can stabilize a wide range of bullet weights. The M4 barrel extension integrates smoothly with standard AR-15 receivers, and the non–chrome-lined bore keeps the focus on consistent performance. Luth-AR’s attention to detail and proven manufacturing make this barrel a practical choice for a straightforward, no-nonsense AR build.
