Rise Armament RA-140 Super Sporting Trigger 3.5 lbs Single Stage

Rise Armament RA-140 Super Sporting Trigger 3.5 lbs Single Stage

Also known as the Black Fallout, the RA-140 SST is a high-performing, cost-effective upgrade to replace mil-spec triggers.

An Affordable Enhancement That Drops into Any Mil-Spec Lower Receiver. Drop-in trigger enhancements have been one fast, easy way to upgrade an AR-15 for years, but many enhanced trigger units on the market can run into the multiple hundreds of dollars, leaving budget-minded shooters in the lurch. RISE Armament fills the gap with its AR-15 Super Sport Trigger, an affordable enhancement that drops in easily in any mil-spec lower receiver.

Each RISE Armament AR-15 Super Sport Trigger is machined from a combination of heat-treated tool steel and aluminum and provides shooters with a single-stage trigger pull breaking at a clean, crisp 3.5 pounds straight from the factory. Consumers can choose between curved RA140BLKAWP or flat trigger shoes RA140FAWPBLK.

Also included with the RISE Armament AR-15 Super Sport Trigger are a pair of anti-walk trigger pins, so you can be sure your pins won't ever work loose under strings of fire.
