Been waiting to do this so badly. Can't spend the money now though. Maybe this summer.

 

[Kruel J]

Jeez, I'm digging it! If I could actually see it. How about a better picture of that beauty?!

 

[DRZ400S]

Any better?

Been thinking about this as well. What type of lower? Glock mags?
I saw 80% 9mm lowers on a couple of sites as well.

Yes, glock mags the lower is a NFA "New Frontier Arms"

I'd love to build an SBR of that..

The 9mm pistol carbine thing has bit me too. I like the finish on your build. But I am curious about something. Why did you go the limited route of a "Glock" mag specific receiver? Why not use a standard AR receiver with a mag block. Then you can use any upper you want and go back to 9mm? That is what I did with this one. 80% poloymer receiver with a mag block to accept Colt Uzi style stick mags. The one pictured is a 25 round mag. If you need more capacity. Go after market extended Uzi mags and alter it for the mag catch.

The reason why I went with a glock specific lower is...
1.) I have a glock handgun
2.) The mag block in a standard AR can move if slamming the magazine home. "Been there done that no thanks"
3.) Cheap magazines
4.) Looks better to me having a magwell the same size of the magazine
5.) I used a standard slick side 556 upper no problem
6.) I can switch out the upper to a 40 S&W pop in a 40 S&W mag and I am good to go
7.) I have plenty of other AR no need to switch out uppers or fiddle with taking out a Mag block

Yup the 9mm thing got me too. But this is a two-stamp suppressed SBR in-waiting ...



Went with a Colt-pattern QC-10 lower and a sidecharging upper to reduce blowback gassing me in the face when supressed. Just built it last week and shot it yesterday up in the hills above Washougal. Worked flawlessly with the JP bolt and buffer combo.

Yeah, I had to plug the gas tube inlet hole to prevent gas blow back.

Fare enough.

I do like that receiver. For some reason an AR style receiver, to me, does not look right with an angled Glock mag. I like this receiver because of the straight stick mags. Just my opinion............carry on.

Love mine, I need a current picture. I put done Daniel Defense sights on it dice and a thread protector. Not sure what I want in the muzzle yet.

What upper and lower did you use?
That looks really nice.

I would have to go with a glock since I own a few of them and have a half dozen stick mags.

 

[SFGIANTSGUY28]

I went with a colt qc10 lower, cmt slickside upper, JP bolt and SCS housed in a maxim defense cqb brace ( on backorder ). 8in BA barrel wraped in a bcm kmr rail.
