The LMT Monolithic 5.56x45 NATO 16" Mid Length Barrel Black is purpose-built for shooters running LMT MRP or MRP CQB monolithic upper receivers. This 16" chrome-lined barrel combines a government/SOCOM profile with a low profile gas block, midlength straight gas tube, and an A2 birdcage flash hider installed at the muzzle, delivering dependable performance and consistent accuracy in a compact package.

Designed as a dedicated AR-15 barrel assembly, this model is ideal for range use, training, and general-purpose rifle builds where reliability and longevity matter. The cryogenic treatment and phosphate plus chrome-lined finish support long service life under regular use, while the midlength gas system helps maintain smooth cycling.
