Geissele SSA-X lightning bow trigger has a clean crisp break - excellent for range work and competition. A bit light for a true duty rifle in my opinion - I prefer more first stage take up on duty guns. Perfect for precision shooting.
Geissele SSA-X lightning bow is the best trigger Ive shot. Two stage but feels almost like a one stage because the first stage is so short. Break is glass clean. Reset is audible and tactile. Love it on any of my serious rifles.
Geissele SSA-X lightning bow trigger has a positive audible reset thats easy to feel. Two stage with a short first stage take up. Second stage breaks at the set weight cleanly. Worth the premium price for serious rifle builds.
Geisseles SSA-X has the shorter reset Im used to from carbine class triggers. The lightning bow curve fits my finger better than a flat trigger does for fast strings. Two stage but the first stage is so short it almost feels like a one stage. Worth the price.
geissele SSA-X with lightning bow is a two stage trigger with a wider shoe. takeup is smooth, the wall breaks like glass at the listed weight. reset is short and tactile. drop in install on a mil spec lower was direct, no fitting
super semi auto X with lightning bow is geissele top shelf. two stage break is crisp, the lightning bow shoe gives a wider trigger face for finger placement. drop in on a mil spec lower is direct, no fitting
Geissele SSA-X lightning bow trigger drops in to a milspec lower with the standard pin set. Cassette is self-contained. Pull is glass smooth with a defined break. Reset is short and audible. Premium trigger that lives up to its reputation.
Geissele SSA-X with the lightning bow shape is the best trigger Ive shot. Short reset, defined wall, clean break. Two stage but feels almost like a one stage. Pricey but worth it for serious rifles.
