Rise Armament Rev 535 Trigger Features The Rise Armament Rev 535 trigger uses a slide-and-snap design with built-in pins letting an owner drop it into a mil-spec AR lower without tools screws or punches. This dramatically cuts installation time compared to a traditional drop-in trigger that requires separate pins and a punch set. The single-stage design breaks cleanly between 3 and 3.5 lbs with no perceptible take-up before the wall giving the shooter a predictable repeatable release. Internal components are nickel boron-coated heat-treated S7 tool steel chosen for smooth cycling and long-term wear resistance. The trigger housing is precision-machined from 6061 aluminum and anodized black for durability and the kit includes both flat and curved blade faces that swap in seconds to match shooter preference. This flexibility lets one trigger serve multiple roles from a flat-faced target setup to a curved blade for duty or home-defense use. Made in the USA in Broken Arrow Oklahoma the Rev 535 is backed by Rise Armament s lifetime manufacturing warranty and performance guarantee. For any AR owner looking to improve trigger feel and speed up follow-up shots the Rev 535 s quick installation and crisp break make it a straightforward upgrade.
