ERGO Ambidextrous Original Grip 

The original Ergo Grip, developed by Steve Hines, was the first truly ergonomic, shooter focused grip for AR platform rifles. Designed for performance by creating a better interface between the shooter and firearm, the Ergo Grip is still the standard by which positive grip and shooter comfort are measured. The Ergo Grip comes with the patented Gapper™ for increased comfort.

This grip was purchased by the U.S. Military for use on the original SPR and MK 12 rifles in 2001.

RIGID models are molded into a hard polymer grip for a firm feel while SUREGRIP™ models feature an over-molded rubber-like surface for a more positive grip. Both grip styles are designed to help prevent fatigue and enhance weapon control.

 TriggerTech Adjustable Flat Trigger (Optional Upgrade)

Features a straight trigger lever pad with Frictionless Release Technology.  Drop-in with a short, two-stage action, designed to feel like a 1911 trigger providing a true zero-creep break and an extremely short overtravel and reset.  Utilizing CLKR Technology, the pull weight is quickly and confidently adjusted from 2.5-5.0 lbs in 2oz increments from a set screw with the trigger installed.  The changing of the pull weight also has no effect on the hammer force so you get dependable primer strikes at every weight.
