Brownells 75th Anniversary - A Shooting Heritage

A Trigger That Adapts To the Shooter - Not the Other Way Around!

The Airborne Arms AAST Geronimo Trigger System is not a one-size-fits-all replacement trigger. The single-stage Geronimo trigger is built-around Airborne’s M.S.A.T. technology (Modular Shooter Adaptive Trigger) that allows it to be adapted to the shooting style of each shooter. Everything....OK, almost everything is adjustable, including hammer/trigger spring tension (hence trigger pull weight) and replaceable 7075 T6 aluminum trigger shoes.

The AAST Geronimo Trigger comes with a straight trigger shoe that is sized so it fits smaller hands, yet is still easily manageable by shooters with bigger mitts, too. A properly fitting trigger shoe improves shooter accuracy overall, and it even improves split times between shots, as well as accuracy during rapid fire sequences. This shoe can be interchanged with other shoe configurations from Airborne Arms (sold separately).

In addition, oversized anti-walk/rotation hammer and trigger pins keep your Geronimo trigger in place in the receiver, without wobble that can affect consistency and accuracy. Trigger pull weight is adjusted by swapping in and out the included springs until you find the pull that’s right for you.

  • Trigger available with Red or Black trigger shoe
  • Lightweight hammer design keeps lock time to the barest minimum
  • Key parts machined from A2 tool steel
  • Trigger shoe machined from a solid piece of 7075 T6 aluminum billet
  • Designed, tested, and manufactured entirely in the USA

Adaptability aside, the AAST Geronimo Trigger (named in honor of the U.S. Army 509th Airborne infantry regiment), give classic target trigger performance. It’s machined from high-grade A2 tool steel alloy, with hand-ground and polished contact surfaces to ensure a creep-free trigger pull and a crisp, abrupt, consistent break. Maybe best of all, Airborne Arms achieves all of this in a trigger that sells for less than $200. Get one today and see for yourself!
