DIY: AR-15 Trigger Installation – RISE Armament Drop-In Assembly
Here's how to install a new trigger into your AR-15. This is a step-by-step process installing a drop-in assembly from RISE Armament.
Rise Armament is an Oklahoma based manufacturer focused on AR platform rifles, premium drop in triggers, and precision AR parts. The company grew out of a machining operation that served the oil and aerospace industries, and it brings that background in tight tolerance manufacturing to every firearm and component it produces. From the 1121XR precision rifle to RAVE 140 and RA 535 triggers, Rise Armament has built a reputation for accurate, reliable gear that is designed, machined, and assembled in Broken Arrow, Oklahoma.

Rise Armament puts trigger performance at the center of its brand. Single stage triggers such as the RA 535 Advanced Performance Trigger and RA 434 High Performance Trigger are engineered for minimal creep, crisp breaks around 3.5 pounds, and fast, tactile resets that help shooters stay on target through rapid strings of fire. The RAVE 140 line builds on the successful RA 140 Super Sporting Trigger with a budget friendly housing, anti walk pins, and pull weights that suit a wide range of AR builds.
Rise Armament designs its rifles and parts for real use in competition, training, and professional roles. Law enforcement oriented models and the Watchman XR series pair upgraded triggers with premium barrels and free floating handguards to support accurate fire at extended distances. Many rifles ship with sub MOA accuracy guarantees and are tuned to run reliably with common duty and match ammunition, giving shooters confidence from the range to the field.
Rise Armament emphasizes in house production and quality control. Receivers, handguards, triggers, and many small parts are machined in their Oklahoma facility, where the team draws on experience in aerospace and oilfield fabrication. Components are built from tool steel, stainless steel, and quality aluminum, then treated with coatings such as nickel Teflon, nickel boron, and black nitride to enhance wear resistance and corrosion protection. The goal is to give shooters rifles and triggers that hold their feel and accuracy after high round counts.






Rise Armament focuses on AR platform products, including complete rifles, precision drop in triggers, and AR parts such as handguards, bolt carrier groups, and small parts kits.
Rise triggers are designed as self contained drop in units with crisp single stage breaks, short resets, and consistent pull weights, making them a straightforward upgrade for most AR 15 style lowers. Models like the RA 535, RA 434, RAVE 140, LE145, and BLITZ cover a range of shooting roles and budgets.
