When it’s time to choose a trigger for your precision AR build, you want the best trigger money can buy. It only makes sense to use a trigger like the one our country’s best shooters are supplied with when it counts most.

Geissele SSA-E Trigger: A Combat-Proven Two-Stage Trigger

The Geissele SSA-E is a fine-tuned trigger that is designed for reliability and accuracy. This trigger features a light first stage of ~2.3 pounds and a crisp second stage that features a candy-like break at ~1.1 pounds. This smooth operating trigger is just what you want for an SPR or Squad Designated Marksman type rifle. It is a precision, match-quality trigger that steers clear of the variables that concern shooters when looking at an adjustable trigger.

This trigger features trigger and hammer pins of hardened 4140 chrome moly. You can rely on their durability. Lock time is reduced from the Mil-Spec standard of 8.5 milliseconds to 5.1 milliseconds. The lightweight hammer combined with a full strength spring give a fast, foolproof performance you can be confident in every time you head for the range. The lightweight hammer also reduces the impulse felt on firing, keeping you steady on target.

The Geissele SSA-E Super Semi-Automatic Enhanced Trigger is combat ready, built to deliver the confidence and speed you need in competition. Geissele triggers are precision designed and machined by proud American craftsmen in North Wales, Pennsylvania, from only the best quality materials.
