Great kit for most builds
Everything you need and nothing you don't. 99% change out the grip and trigger anyways. The only issue is the bolt release required significant filing to fit my CC lower.

Perfect price for a parts kit where you want to get a bit personal with the grip and the trigger. All came in nice little zip bags

Works great
So glad I can buy kits without specific parts. I got an aftermarket trigger, and would hate to have a bunch of spare parts being unused.||Everything fit great on my Aero lower.

Good Kit - Great Price
I love the fact that TNA offers different configurations of this kit with or without trigger groups, grips, safety's etc. In the end, it's virtually identical to DMPS, NEA or other kits and the price is great. ||Very happy I can pick up this kit without the extra expense of a grip I won't use and a trigger I'd probably upgrade to custom trigger anyway. Thumbs up and hats off!

Great kit
Everything fit perfectly into my Aero Precision stripped lower. The finish is great. I will definitely use this kit in my next AR.
