As expected
Great value for the price. Quality parts |Thank you TNA

Great Value
The roll pins seemed a little soft compared to others I've used in the past. regardless still a great value.
-
Great kit
Used on my first AR build, everything fit flawlessly in my nea lower, nothing missing or out of spec. trigger is heavy and rough, but that is milspec and not a fault of the kit. Would recommend, especially for the price!
-
Solid kit.
This is a great starter LPK for a bang around rifle or a first build. I've bought two and they both work great. Only complaint would be the second one didn't come in the neat TNA packaging that the first one did.
-
Good Value
I half expected something to be wrong/missing/cheap based on the price, but I was mistaken. Everything fit well and even the trigger is decently crispy, albeit a bit heavy; that is mil-spec for you. All I could complain about is the flat head pistol grip screw, which is me being picky. Such a good price.
-
nice LPK
Can't complain... everything was there. Sear areas aren't that rough. Trigger pull is as heavy as can be expected with Mil-Spec.
-
Perfect!
Used this LPK for my first AR build. Had everything I needed and all fit flawless on my NEA lower.
-
You need this kit!
This is an excellent parts kit. It comes with everything you need to assemble your lower reciever. I bought this for a new ar-15 build and it made the assembly a lot easier.

Works as expected in NEA lower
Installed in my first AR15 in an NEA lower. Probably the cheapest kit around. Really the only issue I have has that the trigger pull feels REALLY HEAVY, especially compared to my Windham AR15 and my service C7A2. But I guess that's not really a fair comparison since both those rifles have been well broken in. Like all Mil-spec triggers it should improve in time. Would also be since if it came with some spare small springs since I lost my selector detent spring and wasted an hour searching for it! Careless gunsmiths need not apply!

Awesome Kit
Bought this lower parts kit from TNA because it was the cheapest generic one I could find. I used it on my first AR build and I'm very pleased with it. Everything fits and functions as it should and the trigger, although heavy (which is expected), actually has a very nice crisp break. Overall, a great LPK and you won't find it anywhere else at a better price!

Affordable LPK. Good kit.
Pretty generic / run of the mill LPK. Trigger is what you'd expect, typical heavy gritty mil-spec trigger. Considering the fact that most "after-market" triggers are more than this entire LPK, you shouldn't be surprised. If you have used a generic mil-spec AR trigger before, then you should know what to expect. ||The pins all fit properly, would be nice to get an extra brass retaining pin since mine got launched into orbit when i was sliding the forward upper retaining pin into place, luckily managed to find it though. ||Another thing that could be good for first-time builders like myself would be a simple diagram or labels on each individual packet to say what components are included in each baggie. Overall this is a non-issue if you're experienced, but it could save some newbies a few extra minutes from trying to get all the pieces in order.

Nice kit
Used the kit to build my first AR. Everything went together nicely, didn't have to fuss about any of the parts. Trigger has a normal mil-spec grittiness to it. For the money its a great buy.
