There is another kit the same as this one but with a carbine gas system. So whats the difference mid length vs carbine gas system?

PSA 16
PSA 16" 5.56 NATO 1:7 Midlength Nitride 13.5" Lightweight M-Lok MOE EPT Rifle Kit w/ MBUS Sight Set
BEST ANSWER: This is all based on reading, but the answer that I get is that the mid-length gas system will probably have a little less recoil due to less gas pressure pushing the bolt back, but sufficient pressure to cycle. I also read that carbine length seems better for full-auto or an adjustable gas block. I'm getting 16" mid-length.
Will this work with SKU:516446970?

BEST ANSWER: To the best of my knowledge, these should be compatible, particularly since they are both PSA products.
Is the stock mil- spec or commercial spec?

Very reliable
I got this kit and slapped it together on an Anderson stripped lower. I've run 2 or 3 thousand rounds through it with out a single problem. I only run Gold Dot ammo through her. I clean her every 500 or so. I train for malfunction clearing and never have to use said training... Kinda disappointing.

I shoot 3 gun with it. Not the best choice but funny when you beat guys with 3 or 4 thousand into their builds. Not always the case.

2 MOA consistent. At the 300 meter range the other day and with an EOTech on super dim you can hit clay pigeons every 3rd shot or so... When you're not cross-eyed because of color crossover!?!

Hope this helps.

Great first rifle. Can't beat the price either.
Great set up for my first build. Put about 200 rounds of cheap ammo through it so far with no issue.

Good quality overall
I put the kit together with a Spikes Crusader lower. Took a couple of hours. The fit and finish of the products is great. The rifle fires fine. I had some issues running a metal magazine. After switching to P Mags the rifle ran wonderfully without a hiccup.The m lok rail is great. It's lightweight and functional. The trigger is very smooth.
Cons- Why would PSA make a carbine length 16 inch barrel? Mid length should be standard. The other issue I have is the plastic Magpul sights. They work, but I plan to upgrade them to MBUS pros in the future.There is no magazine included which is disappointing. The stock is very wobbly. I plan to either upgrade to a Magpul CTR or BCM gunfighter.

Worth the price. Easy to build.
Only took the gun a week to arrive. It was my first build and took me under an hour.
