What is the difference between mid length gas sys. And carbine gas sys.?

BEST ANSWER: Midlength is a little bit softer shooting since it has a few inches more of gas tube. The carbine is a bit harsher.

Not an Absolute perfect fit, but shot well
It was a little loose at first on the Aero Precision M4e1 lower, but the Aero's set screw had it all tightened up. It shot well on its first 120rds, no hiccups. Looks really nice, handguard feels great in hand.

So far so good!
The kit came nicely packaged. Assembly was easy, the parts looked to be machined nicely, but the finish on them is easy to scratch. This is not a deal breaker for me. A gun's meant to be used and the blemishes give them character. I've put 300 Federal 5.56 rounds through it and so far I've had zero issues.

Good value build
Awesome value build. Attached it to an 80% lower I had finished earlier and it looks great. Has chewed through brass and steel ammo alike with no issues so far. This MLOK rail is a lot more slim and low profile than many I've seen and just looks good as well. Currently have the MLOK AFG on it and it makes for a great combination, the rail is slim enough I can wrap my thumb around the top of the rail while using the AFG for a really nice hold. It will smack steel targets at 100yds out with a red dot consistently which is all I need from it.
Added MLOK AFG snd VTAC sling. Great looking rifle, ready for an optic now.

Phenomenal rifle kit
I was blown away by the quality of this rifle, for as much as I paid I expected so much less than what I actually got. This was my first AR-15 build and it was incredibly easy. I do have some experience with M4s but did not expect it to be as simple as it was. My only qualm is that the finish on the rifle has the tendency to scratch easily however, at the end of the day that doesn't affect its performance so I could not be more pleased.
