Geissele ssa-e 05-171 large pin - Geissele AR-15 Super Semi-Automatic Enhanced (SSA-E) Large Pin Trigger

This fits perfectly in my Colt Sporter Lightweight lower receiver. I have not had a chance firing it, but it feels absolutely amazing just doing a function test. Installation was very easy as well. Price is up there, but you get what you pay for. And Geissele is just that. Great quality, design and workmanship. I’m very happy purchasing this trigger. And for my next lower receiver build, it will have a Geissele trigger no doubt!
