E M on Dec 25, 2018

What is the profile of the buffer tube, is it Mil- Spec or Civilian?
Alessandro S on Feb 1, 2019

It doesn’t seem to be a quad rail, but can rails be added to the sides and the bottom?
Stan B on Jan 4, 2019
BEST ANSWER: Yes, you could buy rail sections for it or just buy accessories meant to mount to MLOK.
What lower do you suggest to complete the build?
Edmond S on Jul 2, 2019
BEST ANSWER: Any lower will do. Find the cheapest one, or mill your own from an 80% lower. Will make no difference in the performance of your rifle. Save money for a decent drop-in trigger.
First time building an AR here, can anyone recommend a site or video showing how to put this together?
David C on Jun 2, 2019
Welcome to the club! The upper (which is harder to assemble) is already assembled so that's all you'll need.
God Bless!
Are the stock and grip actual Magpul parts?

Beautiful build kit, missing sights out of box.
For my first build, it went very smoothly. The finished rifle is beautiful and I'm very happy with the finish of the product. My only complaint is that I didn't receive the sights in the box. I've tried the contact us Friday but haven't heard anything yet. Will change review if my issue is fixed

Great buy!!
Bought this kit for a budget gun to keep in my camper at the river. I replaced the stock with an A2 style. I also added reduced power trigger springs. 5-20x56 Nightforce SHV. I’ve put almost 500 rounds through it now. All rounds fired were American Eagle Varmint & Predator 50 gr. Hollow point. Accuracy is great! Consistent and repeatable impacts out to my furthest range with this rifle of 450 yards. So far it has cycled every time that I pulled the trigger. Fit and finish are perfect for a package at this cost. I will definitely watch for sales and shop here again.

I would do it again.
I purchased mine online one weekend and had it by Thursday. Shot it Saturday with a mil-spec lower. It has run absolutely flawless. Mine likes +75 gr. ammo. You can bet on 1.5” moa with 77gr BLK or 77gr PPU. BUY ONE!

Fast and Fun Build
I really enjoyed my first build using this kit. Everything was delivered just a few days after order was placed. All of the parts came nicely boxed and kitted so that it was easy to identify parts needed for each step of the build.

Great fit and finish. Easy build and I am a rookie. Shot great first time out without failure. My only regret is I didn’t get a few of them.
I would definitely recommend this kit to someone wanting to build their own rifle. Took about 2 hours because I’m slow. Could easily do 1 in 30 minutes.

Perfect fit
This was the perfect upper for my Anderson lower. Assembly was spot on. No issues with any of the parts, fit or finish. I did change out the trigger for a 2# comp trigger. Shot a 1 " group once it was sighted in.
Lower build.
completed build.

Very impressed, this was my very first build and I paired it with a ATI lower and the fit was perfect. I’m definitely going to be buying more in the future from PSA
