9mm SBR

[stephen87]

If you could have any pistol caliber SBR, what would it be? I'm debating a 9mm SBR that uses Glock magazines and can't figure out what I want. I'm thinking making a KRISS Vector, but it's so pricey. Let's hear your choices INGO.

IF I could have any ONE, it would be an MP5A2. However, if I had to choose one in my budget, it would be the Vector.

Colt AR pattern 9mm. Building one right now. 8" CMMG upper and lower, Form 1 has been filed. Right now it's in either a pistol form or I use a Hahn mag block and run it on one of my SBR lowers.

Mags and parts are cheaper than others. I will end up with just right at $1000 total in it with the tax stamp.

I like the MPX, but not at that price and for what they are asking for one mag, you can buy four 32 round mags for a 9mm AR.

My .2 cents is a AR platform there are plenty of parts to be had and modified. I love the MPX but the mags and if you need a spare part forget about finding one. Im building one now on a Quarter Circle 10 lower with Glock mags in 9mm waiting on the stamp. With all the filings im sure I wont get my stamp back till next year.

I built one years ago, shot it a few times then it sat in the safe for a couple of years until I sold it. Not sure why but I never really enjoyed it like I thought I would.

I like that. It's a shame you did not enjoy it.

You can get a HK clone cheaper than you can buy a Kriss. Find a Coharie FS94, (fake suppressor), do your form 1, and remove the fake can.
You can get a clone for around $1500, and they go up from there. There are several brands available. MP5 mags start at about $30 for new clone stuff, about $75 for German.

I was looking into one, the MP5 clones, I also was looking at a Vector as well. I ended up going with the CZ Scorpion Evo S1. When they come back in stock you should be able to snag one for around $800-$850 sometimes less. 30 round mags are only $20 and are regularly found in stock.

I had a 9mm AR and never really took to it, but I really enjoy the CZ.

I went AR platform just so you can have the versatility of swapping if you choose

I would vote for an AR series 9mm. For me I am going to go with a Glock compatible lower.

I have an AR SBR and really enjoy it. I've always wanted to try an MP5 clone though. To me most of the rest are just too expensive for what they are. Hopefully someday Glock makes one.

Building an AR is probably the most affordable way to go, but it is my least favorite. Just didn't care for it, and generally, you have to get good mags to make them run right. The cheap mags can be a pain in the butt.
For an AR style, the MPX is the way to go. Much smaller with the elimination of the recoil spring and tube. The mags are expensive, but, they are still cheaper than Colt mags.

Sub gun mags are just expensive, it is what it is.

The $16.99 a pop ASC mags I'm running in my 9mm AR pistol works fine. I have not had any problems with them.

Which mag block are you using or is it a dedicated lower?

MPX mags are ~$60.00. The "best" Colt-pattern SMG mags (Colt/Metalform, Spikes, etc) are about $40.00. The current generation of ASC mags, which Colt now uses as OEM, seem to be pretty solid and can be had for less than $25.00.

Both. When I have the upper on one of my SBR lowers, I'm using the Hahn drop in block. It's the top loading block. When it's a pistol, a CMMG lower.

When on a SBR lower, no bolt hold because of not having the different bolt release. On the pistol lower, it locks back.

No issues with either, suppressed or unsuppressed.

You can get the ASC mags at Bullpup Armory for $16.99 a piece. Buy 3 or more and it's free shipping.

Cool. It's nice to hear there are some more affordable mags that run well.

When you load them up for the first time, they are tight.

Load them up and let them sit for a while. It can be a PITA for the 31st and 32nd round the first time or 2.

Same with the Metalforms. Super tight. A Lula loader was the best $40 I ever spent.
