How long is the buffer tube?
Scott W on Oct 9, 2018
BEST ANSWER: Maybe 10. Inches
Why does it not come with a castle nut?
DANIEL H on May 20, 2018
BEST ANSWER: The tube itself acts as a retainer to the rear take down pin spring. I personally did not like that when I had my pistol, I would have rather had a castle nut because I always felt that the buffer tube would come loose. For the six months I had my pistol I never had a problem with it.
The carbine buffer and spring work with an 8.5” barrel?
John B on Mar 4, 2019
BEST ANSWER: The length of the barrel has nothing to do with the buffer spring. It will be fine.Enter an answer to this question.
Does the Sig Sauer SBX brace fit on this?
Chi C on Dec 27, 2018
BEST ANSWER: Hi Chi, it appears that the Sig brace requires a thinner diameter buffer tube than the one in this kit. This tube is larger in diameter than a milspec/commercial tube, and the Sig brace looks to need a thinner tube then even those.
Hi Bigdog71 Will this kit work with shockwave?
Beast on May 20, 2019
BEST ANSWER: Yes it will. You will just use the Shockwave buffer tube rather than the one provided in the kit.
Will this work with an SBA3 Brace?
Hayden G on Mar 5, 2019
BEST ANSWER: No, the SBA3 works with a carbine buffer tube that is included with the brace.
Will the shockwave fit on this?
Gordon P on Dec 12, 2018
BEST ANSWER: Yes it does! I have a shockwave on mine. No issues.
will this kit work on a ar9 ?
cliff k on Jan 23, 2019
BEST ANSWER: Yes will work just fine you may have to change the buffer out though
What is the OD of the buffer tube?
Alexander H on Dec 30, 2018
BEST ANSWER: 1.17 inches.

Affordable, Reliable & Durable
This is an affordable, reliable, and very durable build kit. It has everything you need to get started. And my finished build has been a ton of fun to shoot.

It works well
I just assembled my first ar 15, and I purchased this build kit, because a friend told me it was entry level, and it was on sale. I am satisfied

Works great in my 7.62x39 AR pistol.
Works great in my AR pistol chambered in 7.62x39.  Never a light strike even with the bigger round.

Receiver extension that I got was not the one shown in the picture, Not a big deal but do know just like the buffer you get what you get not necessarily what you PAID for but you get something usable which I guess is fair. And unfortunately I did not get the buffer with the logo. (would’ve loved the logo) everything else was as shown and all parts fit well.
