Cade K on Nov 24, 2018
BEST ANSWER: It is now, my friend!
Can I use a suppressor with the rail on this build?
Travis C on Aug 26, 2018
BEST ANSWER: The PSA flash can has an o.d. of 1.20”. Measuring my PSA 12” mlok slant rail and anything larger then 1.20” might make contact while firing due to barrel whip and close tolerances. Most 5.56 rated suppressors are around 1.5” o.d. So in general I would say no a suppressor cannot be with this combination of a 10.5” barrel, and this particular 12” rail.
Can this be shipped to California?
Ed B on Jan 7, 2019
BEST ANSWER: NO!
Does the build kit include everything for a stripped lower?
David S on Jul 30, 2018
BEST ANSWER: Absolutely! Only thing I added was a sling loop under the castle nut. Great kit and excellent trigger group.
Whats better. Pistol or carbine gas for the 10.5 kit?
jeremiah f on Aug 27, 2018
BEST ANSWER: The dwell time on the carbine length gas system is a little bit short with a 10.5" barrel; the dwell time on a pistol length gas system is a little bit long. I have not experienced any problems with my carbine length gas system and 10.5" barrel.

Chunt on Feb 8, 2019
Is the flash can “permanently fixed” (i.e. pinned and welded) to the barrel?
MacBean on Jan 1, 2019
BEST ANSWER: It is my understanding the flash can is screwed on. When the hand guard is removed the fully exposed can will be seen with two flat sides at it's rear. Connecting a wrench here should remove it. There are no welds at the rear of the can. I have not tried to remove mine. Looks cool and gives it a bull barrel look.
Hi is this kit requires SBR from atf or Is this considered a pistol thank you ?
Christian on Jan 28, 2019
BEST ANSWER: If you're "intent" is to build a pistol, it's considered a pistol because of the SBA3 brace (Google SB Tactical ATF Letter). Keep in mind, it is all about "intent"; if you're "intent" is to bypass and use your pistol as an SBR, your "intent" makes it an SBR. This holds true from my research for all AR pistol builds.
Does the 21 OAL refer to the upper? Or the pistol in it’s completed form?
benjiman c on Mar 9, 2019

What are the necessary tools to put this build together?
Dylan H on Feb 5, 2019
BEST ANSWER: A set of roll pin punches, a vice, and a hammer with a polymer strike face and a brass strike face. Maybe some needle nose pliers. Three hands also helps.
Can this be bought in store?
Corey R on Mar 22, 2019
BEST ANSWER: Possibly, but this can be shipped to your door. All you need to pick up from the store is the lower. I love mine.
What is the difference between this kit and the seemingly identical kit with the sku ending with 807 instead of 877?
Mike D on Jan 1, 2019
BEST ANSWER: One model has picitinny rail on top of the free float all the way down. The other only has picitinny on top at the front of the rail where you would put your front sight. Personally, I bought the full length picitinny rail so I could mount a peq box on top. Other wise you have to mount accessories with mlok

What is a shot-peened Carpenter 158 steel?
Herb D on Apr 6, 2019
BEST ANSWER: I'm not a metallurgist but I am a certified armorer and i can tell you C158 steel is what you want your bolt to be made of. The other common option is 9310 steel which is not as durable and in my opinion should be avoided. So in short, C158 is good, and so is this kit.

If I have never built my own gun. How hard is it for someone that doesn’t know how and what exactly else will I need to buy ?
Ranger U on May 2, 2019
BEST ANSWER: It's very easy to build, (You Tube has thousands of regular people doing step by step video instructions. Watch a few of them to judge whether or not you'd feel comfortable doing it yourself).

For additional parts, you'll need the lower receiver, at least one magazine, and some type of aiming device, (Scope, Red Dot, Iron Sights)
