Best Mil-Spec-ish trigger group I've ever used

by

I love this LPK. I bought this kit because I was curious about the trigger and the hammer setup. The trigger is really nice with a crisp break and a short and very positive reset. I even like the bits that I didn't use in my last install, i.e. the bolt catch and the mag release and the safety. I will put those to use in my next beater rifle build. Overall super solid and I'm planning to get a few more of these the next time I see them on sale.

Good item . . worth a try.

Have used this kit in several builds and everything has fit great and has worked flawlessly so far. I have had no issues with this kit and the stainless trigger looks great with a black or a raw lower.

Best Lower Parts Kit

by

Best lower kit of all I have used. Choose it when possible. Have created 12 different builds with this lower kit

Best Buget Lower Parts Kit

by -

I have purchased a couple different brands of budget lower parts kits, and this is by far the best one. This was mounted on an Anderson lower and everything went together perfectly. No complaints so far.

It just works.

by -

It's a cheap LPK that works perfectly well. Weight on the trigger is pretty good, a step up from mil-spec. Stainless trigger also looks super sharp on my AR pistol.

AWESOME LPK, especially with a few cheap upgrades

by -

I like everything about this kit.
STEAL at the sale price.

+ Stainless, well machined trigger and hammer.
+ Hammer is bobbed, so you can add a reduced power hammer spring and still get 100% reliable ignition, while reducing pull weight.

I had a bunch of Magpul MOE grips laying around I bought last year for 5 dollars each, a JPE reduced power enhanced reliability spring kit, and a 1/4-28" set screw with a shortened pistol grip screw.

I didn't even have to polish the engagement surfaces. After adjusting the trigger, installing the reduced power spring set, and installing the Magpul MOE grip, I have a KILLER trigger that breaks at 4 lbs with zero creep, and has a short reset....all for a total of 50 dollars!

I'm happy. This will be my go-to parts kit from here on out.

A solid LPK

by -

This is a decent kit which I installed into an Aero lower with a JP spring kit. All the parts look well machined but I ran into an issue with the hammer. Once installed the hammer would not move without considerable force. I had to sand down and polish both sides that have the slot for the trigger pin. A few minutes of work and this is a solid kit. I will buy again if on sale.

Junk

by -

I wish I had read some of the reviews for The skit before purchasing. I generally purchase Aero lower kits. The one I liked was not in stock, so I went with this kit. Bolt catch spring did not fit. Ended up ruining the spring trying to fix it. Now I have to order another bolt catch spring before I can go any further. Won't be ordering anything else from Anderson

Great LPK, Great Price, PA never fails to satisfy!

Having purchased and installed many of these Anderson LPKs, I can confidently state that anyone who has issues installing LPK this needs to stick to their Lego's and leave the smithing to those of us who know what we are doing. Milspec is milspec, not perfection in a box. Drop in parts are not always drop in. Compared to working on 1911's, installing AR parts is a breeze.

Enough said. Buy this kit, you will like it.

Decent

by -

The kit is packaged nicely. The hammer I received had a broken J spring, so the hammer pin was walking out. I emailed Primary Arms, and they had Anderson send me a non-defective hammer. The trigger pull is very short and crisp for mil-spec. Selector is tight, but I kind of like it. Only the front pivot pin is dimpled, not the takedown pin, which is weird to me. Overall, decent.
