This National Match two-stage trigger from RRA is an excellent trigger for your AR15 rifle. These are used frequently in Varmint and Long Range AR builds where a lighter 2 Stage trigger really helps accuracy and round placement. These triggers come pre-adjusted by Rock River gunsmiths as a matched pair and drop in all mil-spec lowers with no adjustment necessary for an easy drop-in install. Rock River 2-stage NM pins are .1555 in diameter and are not recommended or designed to be used with .154 pins or .170 Colt lower receivers.

Truth be told, the Rock River Arms AR-15 is one of the better rifles that you can find on the market today. Yet, the fact of the matter is, every serious shooter knows that a good shot starts with the trigger. That’s why upgrading your Rock River Arms AR-15 with a Velocity Trigger can drastically improve accuracy. The Velocity Drop-in Trigger reduces the trigger pull to your choice of 3 pounds, 3.5 pounds, 4 pounds, or 4.5 pounds.  What’s more it literally has no trigger creep and a minimal amount of over travel.
