A high quality lower build kit with everything you need to assemble your AR-15 lower into a pistol. Features our Enhanced Polished Trigger (EPT) fire control group which features finely polished contact surfaces and then finished off with a super slick nickel coating.  This results in a trigger which is significantly smoother than a standard Mil-Spec trigger assembly. Pistol kit also includes a Shockwave Blade pistol stabilizer, Shockwave tube, Magpul MOE grip, MOE trigger guard, carbine buffer spring, and standard carbine buffer.

Is this stock legal to put on my ar 15 8.5 barrel?
Derrick J on May 17, 2018
BEST ANSWER: As long as your AR15 is designated as an AOW or a pistol, it is currently legal to use this brace.
What is the buffer weight and spring included?
Andrew S on Nov 18, 2018
BEST ANSWER: standard carbine spring and buffer, so you will need different ones for an ar-9
Does this have the same fire control group as #7780997 ?
Town of Newburgh Fleet J on Jul 7, 2018
BEST ANSWER: Yes, they have the same EPT fire control group.
Can you use it on a 300 aac pistol?
Joel S on Jul 25, 2018
BEST ANSWER: Sure can. That’s what I’m using this kit on. It’s really no different than using it on a 5.56 pistol since it’s just a barrel difference.
Besides a pistol upper kit is this all I need for a stripped lower?
Billy Bass on Sep 12, 2018
BEST ANSWER: Correct. This kit (plus a stripped lower sold separately) will make a complete lower. All you need is a complete upper.
Does this brace have the PSA logo or is it “ghost”?
Zeb S on Jul 9, 2018
BEST ANSWER: No logo. Says "made in U.S.A." very small on left side.

Right side says "shockwave Technologies" and "blade pistol stabilizer". Lettering is about 1/8 inch tall.
Is the brace adjustable or is it locked in one position?
Samuel M on Jul 12, 2018
BEST ANSWER: LOP can be adjusted using a hex wrench.
does it come with the sling attachment point on the rear plate like the picture?
Chris on Sep 7, 2018
BEST ANSWER: It does. It's the exact part pictured
Is the safety selector full auto?

My castle nut wrench doesn't fit , any suggestions?
jerry on Nov 2, 2018
BEST ANSWER: Are you using the correct side of the castle nut? My standard castle but wrench fit and worked fine.
Is the buffer tube mil-spec?
Todd I on Sep 6, 2019
BEST ANSWER: No, it’s a pistol tube upper that only takes the shockwave brace. I believe they have to do that so that the brace can be legally called an arm brace.
Will these work for a AR9? Im seeing mixed reviews online about AR9 and AR15 LPKs being different
Aaron b on Oct 10, 2018
BEST ANSWER: I installed mine on an AR15 but from what I understand it will work for an AR9 also
I have never built a lower. Are instructions included? Is this doable for someone who has never done this before? Thanks for any help you can provide.

Very good value
Was exactly what I was looking for. If you price all this seperate you will pay twice as much. The polished trigger is a Improvement but not as good as a drop in trigger. I am on my 4th pistol build and will be ordering another but in fde.

Everything's in there.
Good build kit to start off any AR build. Rear plate didnt have sling loops like the picture shows (just a standard end plate) but everything went together just fine regardless. Get you one.

Great Little Build Kit
4 Stars for great Customer Service & this kit has almost all the parts that I am looking for.

I'm building a pistol and still waiting on my customized lower to finish this build.

I did not receive the double-loop "latch plate" as shown in the picture. The original packaging had a standard "latch plate" without the loops. Part of the purpose of this build is for a .22lr conversion for my kids and I wanted the sling attachment. I called Customer Service & they explained that the double-loops were out of stock & put a note on my order to ship me one when they became available. I received it a couple of weeks later. Unfortunately, it still doesn't match the one from the picture. This one is missing the key that aligns with the groove on the bottom of the buffer tube. I assume its purpose is to help prevent it from rotating. This is my 1st AR build & it's for the kids, so it'll just be my "learning curve".

I would have given 5 stars, but for 0 out of 2 chances to get me the part that matches the picture, I took one back.

All-in-all ... I'll definitely be a repeat customer for my next one.

Two thumbs up
Amazing quality for the price. The trigger was butter smooth, all the parts were in amazing condition. The blade is very solid once installed. Also palmetto separated each set of parts. This made installation a breeze and organized.

Great kit but lacking
It was a great kit but they gave me the wrong end plate, I called to let them know and they said they would send me the correct end plate but I never received it. A couple weeks later I emailed them and no response so I just bought an end plate from another company. Otherwise a great kit, just an error in customer service for a repeat customer. This is why they are getting 3 stars
