It has the red warning I need a special permit from ATF? Or is it just considered a pistol?
J D on Dec 31, 2018
BEST ANSWER: Other contributors already nailed this, "pistol build, not considered sbr, unless you add a buttstock, etc." I just wanted to add to info regarding the "red box warning." While you're good on federal SBR laws as long as you don't add a buttstock or vertical foregrip, (I'm told AFG's are ok) you'll also need to check your particular state's, county's, and local municipalities laws as well to ensure you're not in potential violation of those.

Legal without federal stamp?
Alabama on Jan 31, 2019
BEST ANSWER: Being as this is a pistol kit, if assembled with the accompanying equipment and NOT a carbine butt stock, this build would constitute a pistol. It also must be installed on a stripped semiautomatic or "pistol" designated lower that was not a rifle at the time of manufacture. Check local jurisdiction to ensure legality beforehand, ATF has the most up to date federal guidance.
Can I use this kit with a Anderson AR-15 lower? Or, does it have to be a pistol lower? This will be my first build.
Brian C on Feb 16, 2019
BEST ANSWER: The only difference between the pistol lower is that it cannot have been registered previously as a rifle, and no butstock only a fixed brace
Do I need a lower that is registered as a pistol?
Jd M on Jan 26, 2019
BEST ANSWER: I have same question basically.. I realize I can't use an existing lower that was assembled as "rifle configuration," but, say I order a stripped lower from PSA, and it's a standard 5.56mm or "multi-cal" lower, do I have to somehow declare or register it as a pistol lower, or is the fact that I'm ordering a pistol build kit, and a stripped lower, obviously not previously built as any configuration sufficient? *I realize this is a question and not an answer, but I'm trying to get a little more clarification on this matter before I inadvertently run afoul of the law.*
Is the barrel chrome lined?
Cody T on Nov 5, 2018
BEST ANSWER: No. Nitride

Anthony B on Apr 10, 2019
Triangular or rounded handguard cap?
The_Chadman on Mar 3, 2019
BEST ANSWER: It is rounded
What size gas block would I need to replace the standard one?
JesseB on Jun 24, 2019
BEST ANSWER: Looking at the contour of the barrel, and being that it's standard, I'd say 0.750 gas block should fit, but first you have to drive out the pins holding in the front sight gas block.
what is the gas port size for the barrel?
Camron O on Dec 1, 2018
BEST ANSWER: Unknown. It cycles 55gr Wolf, and Remington. I also had some 55gr reloads that were very close to factory, no issues.

Great base for a MK18 Clone
I haven't put a lot of rounds through it yet....but so far so good! I love it! great value.I plan to get another and use it for an M16A1 commando clone since I have a spare A1 upper lurking in the parts bin.

Get'em while you can.
Bought a second one after my first order. Excellent AR platform and at a very good price. I used step by step picture instructions to assemble. Everything went together with no issues. The trigger group is good, but I went with ALG ACT trigger and the Anderson MFG with enclosed trigger guard for the lower receiver.

Nice inexpensive firearm
Ran 20 rounds down range, ran perfect, and right on target

Very accurate and reliable so far
Four range trips and around 300 rounds through it so far with no issues shooting a variety of brass cased ammo of different weights from different manufacturers. Benched accuracy has run about 1" at 50 yards. I did switch out the M4 hand guards for slimmer profile, and the rear take-down pin in the kit was undersized and needed to be replaced; it kept walking out. The undersized pin is all that kept this kit from getting five stars.

Top notch!
Materials are superb. Excellent accuracy with very tight groups. We were concerned about the noise but it did not seem any louder than a 18" rifle. So glad to have built this. The lower assembly parts were very well organized by order of operation and I really appreciated that! Totally satisfied with this build kit. Liked it so much I ordered another.
