Includes free anti-walk trigger pins — an added bonus, direct from Rise.
Also known as the Black Fallout, the RA-140 SST is a high-performing, cost-effective upgrade to replace mil-spec triggers. The Rise Armament Black Fallout RA-140 Super Sporting Trigger is a single stage trigger with a 3.5 lb pull weight. The trigger group is a self contained unit designed to allow you to drop it directly in your lower receiver without the assistance of a gunsmith. Drop in triggers can greatly enhance the accuracy of firearm and are an easy custom upgrade to perform. Manufactured and assembled according to strict AS9100 aerospace requirements. RA-140-BLK is now bundled with Rise provided anti-walk pins. Optionally, you may furnish your own 0.154" trigger pins, either mil-spec, the included Anti-Walk, or KNS non-rotating pins both work great. This is a drop-in trigger group, but to ensure best performance the instructions should be read and followed.
