In stock
Designed for durability, reliability, and value, the RISE RA-100 Flat is a workhorse two-stage AR trigger that elevates performance above mil-spec expectations. Precision-machined from S7 tool steel and finished in black nitride, this trigger delivers consistent, long-term durability and a smooth, crisp break ideal for duty, competition, and serious range use.
The RA-100 Flat uses a flat trigger blade and a two-stage pull for predictable control. The first stage measures 1.5 pounds and transitions to a clean three-pound second stage, producing a tactile, audible, and repeatable reset for faster follow-up shots. A robust hammer spring ensures strong primer strikes, including reliable ignition with steel-cased ammunition, and the overall design is profiled to withstand heavy use.
Installation is straightforward. The trigger employs a simplified parts set with no fiddly disconnector assembly or tiny springs to lose, and includes mil-spec hammer and trigger pins for secure fitment. With fewer components than many competitive units, the RA-100 Flat reduces installation complexity while maintaining a rock-solid interface with the fire control group.
Built for hard use and harsh environments, this trigger combines refined ergonomics, dependable function, and durable materials to deliver a professional-grade trigger package at a practical price point.

Great Triiger
I love 2 stage flat triggers. I have a few different brands. Out of all of them, I have two of these. They are the best value in this price range. I'd highly recommend one

Mine arrived yesterday and I threw it in one of my better builds. Comes in nice packaging, first thing that stood out was the finish. Very nice and durable feeling, reminds me of Armor Knight coating Smith and Wesson puts on their slides. The parts being captured made installation a little easier but the standard amount of annoyance is still present. It feels very similar to the multiple Schmid 2-stage triggers I have in several builds. I am team Schmid for sure and keep an eye out for sales. It's comparable to the Geissele G2S I have in my BCM as well - short, smooth take-up, well defined wall and crisp, clean break(like glass). New player in the entry level/budget 2 stage market without a doubt. At 70 dollars with that finish and the sweet flat faced 90 degree trigger this is the best bang for your buck 2 stage trigger at this time and I would not be surprised if the price rises in the near future. See what I did there? Duces.
United StatesGood feel
Feels smooth, and seems to work better than 1 stage.
