At SHOT Show 2015, I ran across a couple of drop-in AR-15 triggers that I don’t believe I had seen before. One was RISE Armament’s RA-535, and the other was KE Arms’ Drop-In Trigger. Both are on the way for reviews, and will be great to compare against the Elftmann Tactical ELF Match Trigger, the Velocity Triggers Velocity AR-15 Trigger, and the CMC Triggers Standard Trigger in 3.5 lb flavor that I’ve already been playing with. I’ve put a lot of rounds through the ELF unit in particular now and will be writing up the review on it in a couple of weeks. A “teaser” video, plus photos of all of the triggers mentioned here, follow. . .
