Is the shoulder on the barrel at the muzzle (behind the threads) ahead of the front edge of the handguard? (i.e., will it accommodate a threaded-on suppressor without the suppressor hitting the front of the handguard?)
Kathy B on Oct 29, 2018
BEST ANSWER: The shoulder, behind the 1/28 threads, is even with the end of the handguard (the back of the screw on flash suppressor is even with the front of the handguard), so yes, you can screw on Most types of cans without interference with the handguard.
Is this a "Complete" kit? Excluding the lower only?
Tommy on Oct 28, 2018
BEST ANSWER: Yes, but you will need to add some kind of sighting system and sling after the build.
Is the SBA3 adjustable in this kit?

Great with one modification....
I’ve put over 600 rounds through mine already. Overall I like the kit and would buy it again. I gave it only four stars because I found that after 120 rounds without cleaning, the bolt would fail to go into full battery. This was due to an excessive amount of carbon building up in the chamber. I also noticed that the polymer thingy on the end of the recoil buffer was coming apart. To fix this, I installed a 9mm recoil buffer and this solved all problems. In my last range outing, I fired 210 rounds through the pistol and had no failures to go into battery (or any other problems) and the action stayed cleaner.
Accuracy at 100yds with iron sights is about a hand print from a rest using 55g FMJ.
Notice the carbon buildup on the edges of the shoulder

Exactly what I was looking for in a Kit
This kit had the perfect match of parts/extras and accessories, in addition to exactly the upper that I was looking for too.
The M-Lok upper, plus the full length top Picatinny rail, made attaching the few extras I add to the build, a very smooth, clean and good looking job.
Good price, shoots great and looks/feels exactly like I wanted it to.
Compact, light weight and I can carry it loaded in my car, since it is a pistol, if I ever felt the needed to.

No better truck gun than this
Took to the range and only put about 160rds of AE and Federal through it. A couple quick double taps and two 30rd mag dumps... no problems so far. Perfect truck gun!
