Take down pins badly discolored, trigger group sticks.

Good kit at a great price

by -

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

Decent LPK but ONLY IF you know how to fix the Reset Issue.

by -

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.

Junk fire control group

by -

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.

Fine, but missing parts.

by -

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.

Great trigger better price!

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.

Best budget improved trigger group

by -

It's no Timney trigger, but you're not paying for one here either. Very happy with the small amount of creep and crisp break. Much better than competetor's similarly smoothed trigger group. ALSO, went through 600 rounds of both brass and steel in one session and no light primer strikes. Gobbled up whatever I fed it. Rest of kit worked as expected. Placed it on a pistol build so the agressive texture on the pistol grip was welcome.

a well kept secret lpk

4.5 lbs out of the box...don't understand one review here that was dissatisfied....I am quite pleased and will buy more!!thanks PA!!

Rough machining causing issue. Fix included.

by -

I ordered these parts for my first build. I gave them 2 stars because there was an issue with my trigger and hammer binding up together and now allowing the trigger to reset. This build was on an AR Pistol, so immediately I thought it was a gas, buffer, spring issue.
After I found others with the same issue online, it was apparent the the parts I received were poorly machined. I have since made the repairs to my fire control group and all is functioning as intended.

ANYONE WHO LOW RATES THIS KIT IS A ROOKIE

All you wanna be gunsmiths on here whining about this lower parts kit have obviously not assembled as many lower receivers as you brag about. It’s easy to hide behind your keyboard and complain about the trigger pull, bolt catch button, poor coating, catch fail, pins won’t lineup, fits are too tight, fits are too lose, your mommy was at the grocery store, whatever. I’ve installed several of these particular parts kit and I can tell you right now this is a solid machined, nice functioning, excellent fit that works perfectly. Like everything else, you went to show off to your friends how awesome you are and couldn’t get it put together under the pressure of being watched which embarrassed you in front of your Xbox friends so you blamed the parts kit and stomped down to mommy’s basement to unleash the keyboard warrior within. Hahaha
