Great kit with a hidden gem

by -

Personally, I think this is the best LPK on the market. The trigger is what stands out...it's worth $40 by itself. Out of the box, the trigger measured exactly 5lbs on my Wheeler Professional, with a short takeup and crisp break. However, I then paired it with a $10 JP Enterprises spring kit, and now it's measuring at 3.4lbs and feels even better. I've used CMC triggers for years, and this is every bit as good for under $50 ($40 if you buy the trigger alone). The rest of the parts are fine...they aren't anything special or fancy, but they fit great and they do the job. I've installed these on about 20 different builds, though admittedly most of them were with Anderson lower receivers, and have never had fitment issues. If you just need a basic mil-spec kit and/or want a gem of a trigger, look no further.

Fantastic

I use this LPK in all my builds.Paired with a 3.5# spring kit it is truly amazing.

Perfect LPK

by -

This is my Third build using this Anderson LPK. Perfect fit with my Spikes, Aero and FN Lower. QC on this LPK is excellent. I would invest on these instead of those Palmetto PSA LPK

Crisp Trigger

by -

Just installed the kit to my stripped lower, did not encounter any problem. The trigger releases smoothly without any take up and the reset was great. The selector was tactile, it shifts from safe to fire and vice versa with a nice sounding click.

Wondered why hammer pin was walking out

by -

I am changing my previous review from 5 stars to 4 stars. It seemed everything was working great until I noticed the pin on the hammer was slowly walking out. Upon inspection, I found out the J-pin inside the hammer was missing. The J-pin sits in the middle grove of the pin preventing it from moving left or right.

Correction on previous review

by -

It is not a J-pin inside the hammer that is missing, rather it was a J-spring.

Smooth Transaction

by -

Always happy to do business with Primary Arms. Fast , smooth, seamless transaction. Great communication and fast shipping.

Just ordered another one.

We are so lucky to have a company like Anderson in our country !
The Stainless kits are smooth like butter !!

Look before you try to install.

by -

Bought a few because they were, well cheap. The last one was totally out of spec. The mag release bar was bent so bad I laughed. Won't be buying anymore Anderson products.

We are happy help you with this per our conversation. Please let us know if there is anything else we may help you with.

Best Milspec LPC out there.

I love how these Stainless kits (hammer and trigger) go together and smooth out after a very short break in.
My two favorite AR-15 platforms both use this kit.
Good stuff !
