Rather than exhume my old thread, I'll begin again.
Basic problem is an older, large-pin Colt lower. Had a Bill Springfield triggerjob in it, which was okay but of questionable longevity. You guys suggested some alternative aftermarket triggergroups, but Geissele seems to have the big rep around here, as long as you had small pins. ADCO has the Geissele SSA with large pins; it is now installed in my Colt and I'm very pleased. Axle tolerances are very tight, so you should have a slave pin, and the hammer spring is stout. Otherwise, it's an easy install, everything fit and functioned, and nothing to adjust. As advertised, the first stage is 2lbs and the second another 2 pounds; Brownells says of the .154" version "...second stage that breaks more like snapping a raw carrot than an icycle..." Test hopped it on quick range run today; 100% function and a great trigger pull. Thanks for the bird dog, and I'm happy to have the large pin option with the Geissele. Now that Colt has reverted to small pins, I have to wonder how much of a problem this could be for owners down the road; at least the Geissele has a rep for longeveity. Moon |
