Anderson Manufacturing AR-15 Lower Parts Kit - Stainless Hammer and Trigger

I am about to tell you something that may completely shock you. Anderson gets such a bad rap that it is amazing and that is ok by me since it keeps the price what I call FAIR. It is a trigger all of them if mil-spec is basically the same. Size, shape or form. Ask yourself what is different? the fact one may be polished better? This trigger has no slop and no grit and it's reset is just fine for a life or liberty rifle. If you pay close attention the rear of the hammer is bobbed. Not only that but they have machined out a wee bit more material there cutting you weight down even more. Less metal in that hammer allows for a faster spring. Anderson takes great pains in design and function and I have no gripes about my trigger in my L or L weapon. (Life or Liberty). Machining is spot on, the polishing is well done, and the weight cut is significant. Spend your money on a good quality bolt and barrel. Don't be so hung up on tacticool.

These are what we would call... the minimum acceptable parts. They work, they are in spec. However there is no noticable difference between this trigger and any other trigger, so if you're getting this one for the cool stainless trigger, you won't find any advantage, in fact this trigger is a bit worse than my factory New Frontier Armory parts kit. That being said that wouldn't matter much, and this would get more stars from me, however, my parts kit was missing the Bolt catch plunger.

Junk fire control group, heavy gritty trigger pull and disconnect issues. installed 2 of these stainless kits on 2 different lowers and will be removing both. ive built several lowers, first time using Anderson LPK and will be last time.

Yes, these triggers will not reset without some filing on the hammer. Google "anderson trigger reset" and you will find the fix. Basically there is a bump on the hammer where the disconnector catches that needs to be filed off and honed. Very easy to do, but it makes me wonder about Anderson QA. Other than that it's good quality and worth the effort for the price, which could be $40-50 if the reset issue was fixed. The only other thing I will add is the hammer spring is very stiff, difficult to install, which makes for a very hard trigger pull. I don't have a scale but my guess it's 10-12 lbs. I ordered some 29 cent standard hammer springs from PA which I expect will bring it down to normal trigger pull of 5-6 lbs. Maybe then I'll give it an extra star.

Great price and quick shipping by Primary. Good lpk kit, nothing missing went into Spikes lower with no problems. Trigger is heavy and gritty, but what can you expect for 29.99. Still a killer deal

Take down pins badly discolored, trigger group sticks.

Bought three kits on sale. All parts were there and fit nicely into Anderson lowers. In fact I got a few extra parts. Quality was fine. No problem with fit.

I used Geissele triggers so I didn't use the stainless steel trigger groups that came with the kit. However, I temporarily installed one set just to see what they were like and didn't like the trigger. Gritty and heavy.

I liked the kit there was nothing wrong with it pretty standard. My only complaint is the parts kit was missing the hammer pin and trigger pin and now I can't finish my lower till I get new ones. I was happy though about the prompt shipping primary arms offer.

It's my first build and my first ar the parts are great and wasn't expecting all of the parts to already be separated in color coded bags that really helped me out to figure what went where the only thing I've got an issue with but not a big one Is the trigger its kinda gritty but nothing a little emery cloth and elbow grease can't fix other than that great it arrived after 3 days and I ordered it on a holiday weekend (not counting Sunday of course) will definitely order more stuff for my build from them great job

It's the worst LPK I ever purchased. Trigger pull is hard and VERY gritty. The finish on the bolt catch button was lightly coated and shows bare metal. For a few bucks more.... PSA is a much much better kit. I've used a lot of them and never had an issue. :) P.A. always has great services. Shipped and received LPK super fast. Only that now I'll have to purchase the fire control group from another manufacturer.
