The Troy Irreg Def 5.56 NATO SBR 11.5 Tan is a short-barreled rifle built through an Irregular Defense collaboration, pairing Troy’s proven semi-automatic 5.56x45mm NATO platform with carefully selected ergonomic upgrades. Its 11.5" threaded barrel is ready for muzzle devices and suppressor use, while the anodized tan finish offers a clean, modern look that complements the included furniture.

This compact SBR ships with a Thril CSS buttstock and magazine for a stable, repeatable cheek weld, plus the Irregular Defense Special K grip and MHS V2 CC foregrip to enhance control during rapid strings of fire. A Micro Flow Enhancer muzzle device is optimized for Irregular Defense suppressors, helping manage gas and recoil. Ideal for range training, practical shooting, and general-purpose defensive roles where a shorter overall length is preferred, this rifle reflects Troy’s reputation for reliable, American-made components and thoughtful design.
