Rise Armament RA-434 High Performance Flat Single-Stage Trigger 3.5 lb - AR-Platform

The Rise Armament RA-434 is a single-stage, flat-faced drop-in trigger built for AR-platform rifles chambered in .223 Remington and .308 Winchester. Part of Rise Armament's High Performance Trigger (HPT) line, the RA-434 is engineered to deliver a clean break and a short, tactile reset that helps competitive shooters and recreational AR builders alike get faster, more accurate follow-up shots.

At the heart of the RA-434 is a 3.5 lb pull weight with virtually no take-up and a crisp single-stage break. The flat trigger face sits naturally under the pad of the finger for improved leverage and consistent pull geometry, shot after shot. After each shot the short reset lets the shooter get back on the sear quickly, shaving precious fractions of a second between strings of fire.

The trigger pack is housed in a 6061 aerospace aluminum cassette that drops directly into a mil-spec AR-15 or AR-10 lower receiver, with internal components built from hardened steel for long service life. The exterior is finished in black hardcoat anodized for corrosion resistance and a low-glare appearance. The complete unit weighs just 2.4 ounces and ships ready to install with anti-walk pins included so the trigger and hammer pins stay locked in place under hard use.

The RA-434 fits most .223 and .308 AR-style platforms, making it a straightforward upgrade for standard AR-15 builds as well as larger AR-10 / LR-308 rifles running a compatible lower. Installation is a simple drop-in swap using the existing trigger and hammer pin holes - no gunsmithing required - so builders can transform the factory trigger feel of an off-the-shelf lower in minutes.
