Parts came coated in surface rust that was visible prior to opening the packaging. The casting on the trigger was poor. Imperfections on the trigger and the finish was uneven. You really do get what you pay for.

I was excited to build my wife’s ar-15 unfortunately they’re out of spec.
Very disappointing bc it’s a KAK lower parts kit seems very good but the mag release parts were terrible and every spring couldn’t fit where intended to fit, also seems like I had missing parts maybe I was going crazy to fit the parts still looked like I was missing parts.
For anyone looking for a lower parts kit on a budget please save up a bit more for higher tier lower kit that are to spec so you won’t have a headache like I did building my wife’s at-15.
I went to my local gun store got a S&W lower kit and everything fit perfectly just a heads up guys on my experience with this KAK lower parts kit.

I got the kit and overall it was pretty good. Only problem was the mag catch plunger. It's out of spec, just a bit too large and thusly very tight. I figured with enough oil it wouldn't be a problem. Well, now my lower can't keep it up so to speak and it's gonna be a gigantic pain to try and extract this plunger past that, the kit was pretty nice. Maybe you'll have better luck than me.

So I'll was about to give this 4 stars but nah. The bolt catch plunger was over sized. Would not fit in any of my lowers, you basically had to sand it down to make it fit. So I give it 2.5 stars actually... because I had to drive to a LGS and purchase a oops kit that cost me another 15 bucks. Basically I could have got a better know brand instead of this. Gas + driving distance + wasting my time for something I should have not even do. Everything else was fine, until installing the bolt catch. 15 bucks for that one little piece! I mean, I could have ordered one just by itself, around 1 dollar or whatever, shipping, then wait again.... but nah... still this made me mad.

It's a pretty straight forward lpk. Everything assembled as it should in a psa lower.My only complaint is there wad a missing a pin for the trigger guard.
Pros:
- Affordable
- installed and aligns easily
Cons:
- missing a key part to install on rifle
- Cheaper quality
