Anderson Lower Parts kits

i have used multiple Anderson Lower Parts kits and i have to say they have worked flawless for me i cant complain for $50

Great kit

by

Just got this kit in the mail today shipping was really fast (and it came to Alaska) just finished installing it together and it fit great and everything works real smooth. Very pleased!

DO NOT BUY...

by

These are not good quality parts. Also the parts may or may not match the picture you see on this website. I purchased several kits and they were two different type of hammers and triggers in the various kits. Some of the kits had these weird "bobbed" hammers. They look like 9mm hammers. The parts also look like they're sourced from some not-so-good sources. NO WHERE NEAR the quality of Schmid sourced parts (the parts that have a "S inside a square" stamp. This is it SUB PAR in quality.

Bad trigger

by

defective front pivot pinThe trigger is not smooth at all. The front pivot pin's channel that the detent rides in is not cut deep enough. The pivot pin got stuck and ended up having to use force to get it back out. Compared the pivot pin with a PSA pivot and could really tell how much its off. Put the PSA pivot in and it works. Ended up damaging my lower though. Don't buy this product.

Pretty good kit.

All the parts were present and everything installed and worked as expected. The trigger is definitely not premium and is a little gravely but for the price I didn't expect any different.

I want the old SS trigger setup back!!

by

I ordered 3 of these right before Christmas and PA had them to me in just a few days!! The "NEW" Anderson trigger with the black hook style trigger is a downgrade in my opinion to the old SS style. I have had to polish up the trigger to make them feel decent as a "mil-spec" trigger. I have just used up the 3rd one and this last one the disconnector was horribly made. Very rough looking and out of spec so much that it was not allowing the trigger to reset after firing. Swapped it out with another disconnector and it works perfectly fine.

Nay !!!

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.

Great survice

by

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

Good product but...

by

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.

Good parts kit for the sale price

by -

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.
