Excellent Milspec Trigger Group(25/03/2018)
An overall excellent milspec style of trigger group. The pull is heavy, but smooth and surprisingly crisp. Very minimal creep and a normal amount of over travel. The only problem I had was the disconnector not fitting well. With the trigger pulled, the disconnector did not have enough travel to catch the hammer without the trigger moving forward. Some careful time on a belt sander fixed the disconnector very easily. If you need a milspec trigger group, do not hesitate to get this one! Remember to pick up a trigger spring, hammer spring, and disconnector spring as this kit does not include them.
Disconnectors(30/03/2018)
Ordered two of them and on both the disconnectors wouldn't engage while the triggers were only very lightly depressed. A "firm" trigger hold back back and they would not engage unless I let some pressure off the trigger..A little time with a file and they now engage with the trigger depressed firmly, although it takes quite a bit of force on the hammer to get it to engage..I think this might be an issue with mild loads not forcing the BCG back with enough force to overcome this resistance from the disconnector. Other than that, they function about as well as any MIl Spec trigger.
Disconnector doesn't fit(25/04/2018)
I bought this to go with my JP trigger springs, It looked good but The trigger Disconnector does not fit inside the trigger. I am not sure which piece is defective.
I am the 3rd of three reviews that have this problem. I would steer clear.
Props to Brownells for their excellent return policy.
Great Deal For the Money(26/07/2018)
I purchased 3 of these trigger groups on 2 different orders at 2 different times. I installed them on 3 different Lowers, an Anderson, DPMS and a Palmetto, all of then fit perfect, all of them were smooth with a crisp trigger break. I was so impressed that I referred them to my Brother and he purchased a set for his rifle with the same good results. You can pay more and get less, just saying!
