Re: CMMG MK-8
I helped a friend get one up an running and it was not a bad setup. Like Match308 said, you can get aluminum G3/HK91 mags for next to nothing ($1/mag or less), but the CMMG lowers that use the G3 mags are only compatible with DPMS uppers...and even then, you have to modify your DPMS upper by removing some material from the walls of the upper to allow the mags to fit properly (the G3/HK91 mags are wider at the mouth than the DPMS/Armalite mags). Also, you lose the LRBHO function that you get with other mags/systems. CMMG and outside sources are working on the LRBHO issue I believe.
Aside from those things, they are decent setups, reliable and very cost effective given the cost of the mags at 1/20 or so the cost of DPMS-pattern mags.

Re: CMMG MK-8
The modification is very easy. Just need to open the slot to accomodate the top of the mag. CMMG has a template LINK <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Trigged</div><div class="ubbcode-body">I have one of the lowers but need the modified uppers. Does anyone sell these already modified or are we going to need to modify our own uppers? </div></div>

Re: CMMG MK-8
The only thing that bothers me is that DPMS changed the height of their flat-top to some proprietary bullshit, so that rails are no longer monolithic.
Wonder if the CMMG could be done with a different upper? Maybe something based on the original DPMS style but billet, like an IRA (Iron Ridge) upper?
I also found these from Fidelis Arms:

The site is out of date, they posted on Northeast shooters board that the g3 sets are in full production.

Here's the link off their Main page to Specials. Wonder if the price is still good?

Re: CMMG MK-8
I spoke to the guy I bought the lower from and he is getting some DPMS Sporticals machined this week. He will send me pics and a price when he has tested them. He also said that CMMG should have them for sale in 2-3 weeks for complete uppers from what I understood.

Re: CMMG MK-8
I have one and they are machined well.
I'm selling the one I have here on the hide.
