BEST ANSWER: It is for an AR-15. However, these will typically work with an AR-10. You might have to adjust the springs a bit but a lot of people use these successfully in AR-10s without issue.

Excellent quality and nicely packaged/organized. Electroplated trigger group is much smoother than standard milspec version. Also came with extra detent and spring which was a pleasant and unexpected surprise.

Great kit
Used in M16 clone as all parts fit like milspec but now has a great FCG.

Nice clean trigger. Came with extra detents and springs for the take down/pivot pins. I will make these standard kits for future builds

Good trigger out of spec parts
Received this kit only a couple days after ordering so hooray prompt shipping. Installed the trigger into an Aero Precision lower. Good trigger feel with minimal creep. However the safety detent will not fit at all in the receiver channel. Ensured receiver was to spec. Now my build is on hold to get a properly fitting detent.

Great FCG
I installed this LPK into three 80% lower receivers I completed and they fit and function flawlessly. The trigger pull on the polished FCG is much smoother than mil-spec parts and greatly improves the feel.

OK kit
Received my PSA AR-15 EPT Classic Lower Parts Kit - 7778133 and found it had all black parts no nickle FCG. It took two phone calls and a lot of extra waiting time to get the FCG exchanged. After that it is all good. The two pins for the trigger and hammer feel a bit undersized they fit loose in holes of the FCG parts and the lower. The nickle parts are not shinny all. They are gray kind like zinc.

Very good quality for the price.
This is my first build. I looked at a number of lower parts kits. I settled on this one based on a few reviews I saw. I did not pay for the polished trigger. I was going to do it myself. After looking at the trigger I decided to install it as is. It is no match trigger but it is a very good mil-spec trigger.

All black parts no nickel trigger
It must be my unlucky day. After waiting for over a week my PSA Defender Classic Lower Parts Kit arrived today. Opened up the box guess what parts are all black no shinny nickel plated firing group. The sticker on the box indeed says 7778133 but where is the silver trigger and hammer ? Will try to call psa tomorrow.....

The Polished Trigger Group is Worth the Extra Fiver
I'm doing my first AR build and doing it on a budget. Value priced and quality are usually words that do not go together but this is a pleasant exception. Everything in this kit is quality. What puts it over the top is the polished trigger group. For the extra $5 over the standard LPK you get a super slick trigger and hammer. No grit at all very little take-up and clean break. Hardware is also packed newbie friendly in separate bags for each part section of the lower. The pistol grip which I had no intention of keeping was so well made I've decided to keep it. It's very stoutly molded with no flashing leftovers you might see on other budget grips. The only hiccup I ran into when installing this LPK was the bolt screw for the grip. It bottomed out way before the bolt had seated into the grip. Maybe receiver maybe the bolt who knows...but an easy fix with just a spacer. You could use a washer or cut the bolt too.
