AAAAAAAA++++++++++ Lighting fast shipping as always!!!!

Cheap mod great performance


After a trigger polish to mirror finish, add this kit and it is a great way to get a better and smoother pull. Cheap and effective way to improve your stock mil trigger. A must have but that's my opinion. Stay safe all



after polishing the trigger and hammer contact points I installed the "Spring Kit" and only had 1 misfire after changing mags, might have been me not paying attention to the release, I was talking to someone and I think I held the charge handle for a split second holding back on slamming forward completely, wasn't paying attention, possibly causing the issue. 150 rounds and only one failure, seems to be fine. worth the money.



Awesome service, fast shipping, great product!

cheap easy upgrade


Cheap upgrade for the trigger. Works great with brass not so much with the harder primers on steel ammo.

Spring job...


Easy way to do a direct replacement of mil spec springs to lighten your pull weight.

Smooth and Light Pull


EZ to install.Desirable results with smooth and light pull. Reset understandably incomparable to exorbitantly priced Drop In Triggers, but nonetheless good to go for use at the range.

The definition of A+ service


Fast shipping and great communication from Primary Arms (as always). Trigger pulls under 5#'s, and made a world of difference when paired with the Spikes Battle Trigger,over milspec.
