Geissele Automatics manufactures confidence, offering quality triggers and components for the warfighter and competitor. They were established in 2004 with the mission to build the highest quality, reliable triggers for competition and their first trigger, the Hi-Speed National Match trigger, was so popular that they were asked by the Department of Defense to produce a select-fire trigger for the United States Special Operations. Again, it was a success and Geissele decided to bring a semi-automatic version to the civilian market for law enforcement and personal protection.

Beware of poor quality...

by -

It is out of spec in comparison to lmt and bcm. The bolt catch is rough with machining marks and does not move freely.
<br>Please save yourself the effort.

Great LPK

I have several of these lower parts kits in my rifles. They fit well and are high quality.

Can’t go wrong

Everything went together perfectly and this kit is high quality. I thought I had an issue with the safety selector, however the issue was with my lower. I plan on using this LPK in future builds.
