Manufacturer's Description

In an effort to help military customers measure and solve rail related problems, Otis not only developed qualification gauges for mil-spec 1913, but also conceived a new patent pending machining process. This resulted in a truly mil-spec 1913 compliant rail, the Otis TRS™.

TRS™ stands for Turned Rail System, an engineered process that delivers the highest quality mounting system available today! The TRS-74 is designed for AR-15 Carbines such as the M4 and provides a perfectly integrated platform to achieve your rifle’s full potential.

Chosen for their versatility, accuracy and reliability, AR-15 Carbines are time tested in the most demanding situations. They call for the very best in mounting systems. Every quality laser, scope, or illuminator needs the same rock-solid mount. Your performance, maybe your life, depends on it!

Whether you are patrolling the mountains of Afghanistan, practicing tactical entry and room clearing, or just emptying mags at the gun club, expect tough, reliable and solid performance! Insist on the only rail that offers superior quality at a competitive price. Ask for the Otis TRS-74.
