cmmg vs dpms 22 upper

5/19/2013 11:36:29 PM

I have an old DPMS .22 upper... The proprietary magazines (that have the extractor built into them) are not only crap, but impossible to find. I am wondering if it is possible to replace the guts of this upper with a CMMG conversion kit? <...

Thank you CMMG

Last November I bought a 16" dedicated .22 upper. After some trouble feeding while breaking it in, the thing runs like a raped ape. A few weeks ago the firing pin broke, at the step near the forward end, where the pin takes on its smallest diamete...

I have two CMMG .22 guns. One I bought in 2010 as a complete rifle, and a upper we bought from Black Rifle. Both of these functioned flawlessly after buzzing the chamber and polishing the feed ramp. We decided to use these for Rim F...

Evolution 25rd magazine FDE vendors

I tried searching with no luck so I figured it was ok to now ask. For the Evolution 25rd FDE .22 Magazines (22AFC40), Can you only order them direct from your website or do you have vendors that sell them? Im gett...

Just got a new Bravo kit mag won t fit either of my Bushmaster Lowers

4/20/2013 8:04:40 PM

Like the title states, mag won't fit in either of my lowers. I have had these since before the ban ended, and never had any trouble with any USGI mags. Also the 5 Black Dog mags I bought work great, so what's the deal with the CMMG mags? ...

dedicated upper bolt swap

4/16/2013 10:41:16 PM

I think about a year ago CMMG had a program where if you bought the standard upper with the standard blued bolt that you could send it in and upgrade to a stainless bolt and carrier at a small cost. I had everything just about packaged toge...

Question about CMMG 22 rimfire dedicated upper

4/16/2013 10:03:01 PM

This question may be a little late since my dedicated upper was delivered today, but, My RR Arms lower has a notched hammer. The information for the conversion kit says not to use a notched hammer. I don't find that in the information...

Which of your 22 bolt groups accept the auto sear trip

4/7/2013 12:13:30 PM

I'd like to buy one of your .22 bolt groups, but I need it to accept the auto sear trip. Bolt groups I'm finding online often differ from what's on your website. For instance, they don't show the cutout on the rear plate for the sear trip, or th...

I have to give a huge thanks to CMMG for their great customer service and technical assistance!! This would still be a work in progress if not for their help with the FF issue (listed in another CMMG posting which was resolved to my satisfaction!...

Factory 9mm complete rifle upper lower fit

3/18/2013 1:42:05 PM

I just bought a brand new 9mm M4 style rifle. Being that the upper and lower are both factory, I kinda figured that it would fit a little but better. Function and accuracy-wise the rifle has been fine (so far), but it just bothers me having the ...

Where to find Gen II CMMG 22Lr Mags

3/17/2013 3:05:02 AM

Does anyone know where to find the new style CMMG Bolt Hold Open 25 round mags? I am specifically looking for the Gen II "skin" type, but if the old grey ones work with the BHOA, that would be good to know as well.

CMMG Mk4 22 complete rifle with 5 56 upper added

I will be looking to buy a complete .22 rifle soon, and not long after will be after a 5.56 upper as well (not CMMG, being in the UK it needs to be a specific straight pull upper) however I've not heard much on how the CMMG mk4 lower holds up to 5...

aluminum anti jam

3/15/2013 3:05:07 AM

I want to put an extended latch on my anti jam handle but even with the stock latch it is already bowing vertically, I thought I had heard something about CMMG coming out with an anti jam charging handle in the aluminum flavor, any word?

Why don t you use constant force springs in your mags

3/12/2013 11:02:53 AM

It seems that this would eliminate the need to have an extra couple of inches in the bottom of the mag, making a shorter overall package. I've been comparing your mags and carriers to some old Ramline mags that I have, and think it would be feasi...

Two stage trigger pull

3/11/2013 2:37:57 PM

I just installed one of your two-stage triggers and the pull weight is off the scale -- literally. I'm guessing that it's above 10 pounds, but can't really tell because my scale only goes to eight pounds. Also the second stage is really gritty w...
