Geissele SSA-X 2-Stage Trigger w/Lightning Bow 05-959

The Geissele SSA-X 2-Stage Trigger w/Lightning Bow 05-959 takes a heavier, more deliberate pull than Geissele's lighter precision triggers and pairs it with a shoe most shooters end up preferring the moment they feel it. First stage weight runs 2.75-3 lbs, second stage comes in at 1.5-1.75 lbs, for a total pull weight of 4.25-4.75 lbs, noticeably firmer than the SSA-E and better suited to a duty or general-purpose rifle where an accidental light pull is a real concern.

That extra weight isn't a downside here, it's the point. A heavier trigger gives more margin under stress, less chance of a surprise break during fast manipulation, while still delivering the crisp, defined wall Geissele triggers are known for. This Geissele SSA 2-stage design stays non-adjustable by design too, so the pull stays consistent instead of drifting from whatever a previous owner or a nervous first install happened to dial in.

The Lightning Bow trigger shoe is the other half of the story. It's a hybrid curved and flat profile that puts more surface area under the finger than a standard curved bow, without going full flat-trigger and losing some of the natural feel shooters are used to. Nanoweapon coating runs across the trigger body and hammer, paired with a chrome nitride disconnect, keeping the pull smooth and the parts corrosion-resistant even with minimal lubrication, exactly what you want in a part that gets run hard and cleaned rarely.

Machined to mil-spec pin dimensions and made entirely in the USA, this Geissele trigger drops into most AR-15 and AR-10 platforms without modification.
