CMMG 9mm Upper

[asmurff]

I have a lot f 9mm ammo, yet it is the caliber we shoot the least. Seriously considering getting a CMMG 9mm upper for one of the M4 clones. Anyone have any experience with these?

I love mine

Colt mags are the best, pricey but worth it.

I have some from the company that supposedly makes them but have not tried them yet.

Magazines at 49-59 dollars is what is holding me back.

Anything Colt branded is pricey. These mags are supposed to be identical if not the same exact ones http://www.jsesurplus.com/ASC9MMSS32RdMagazine.aspx

I used the Hahn top loading block

Anyhow 32 rounds of suppressed goodness  :thumb:

We'll want to see it.

A 9mm AR upper is on my wish list.

Olympic Arms makes a 9mm as well. You dont need the magazine block because the mags are full size.  The mags may work with the CMMG

Lastly you can buy Uzi magazines for next to nothing and modify them to work.

Definitely worth trying.

Brownells has a branded offering on and they are on sale.

I saw those yesterday. Now all I have to do is save up enough to purchase the upper.

Keep in mind you need a different buffer. This http://www.brownells.com/rifle-parts/receiver-amp-action-parts/receivers/upper-receivers/9mm-entry-upper-receiver-kit-sku100010660-54610-105787.aspx  shows all the parts required.

Also the KNS anti rotation pins are a good idea http://www.brownells.com/manufacturers/KNS%20PRECISION%2c%20INCxzzx/index.htm

Not that there is anything wrong with the Yankee Hill, I like their products. However, I still think I'll go with the CMMG. What I originally want was a Kel Tec 2000 but I think it was a pipe dream. First Peloser drove the price for one sky high, and secondly the Glock mag compatible one is the big seller. Those for the Beretta 92 mags seem to be at the bottom of the priority list which is a shame I have plenty of those mags.

I've put a lot of rounds through a KT 2000. I was not impressed.

I posted the YHM just to show the pieces parts involved. Never seen one in the wild

Thanks MG, I'd given up on it anyway, and actually like the idea of the upper better now with other things I've read about the two.
