silverado427 10,708 Posted November 26, 2015 Are their any members that have one ? And are they reliable, and what mags would you use. Quote Share this post Link to post Share on other sites
T Bill 649 Posted November 26, 2015 Have a Colt MT6851DC (20" rifle gas system on a A4 upper) from the early 90s. Has always worked perfectly with brass ammo. Magazine was only 9 rounds I believe. No one have ever come up with a reliable mag in this platform because of the bevel on the ammo. Needs a big curve mag to make it feed properly something difficult on the ar15 platform.

FirearmFrank 2 Posted December 2, 2015 i own one and if you want to shoot steel cased ammo, you must upgrade the firing pin. the standard firing pin is light strikes on the primers of the steel cased ammo. A stiffer spring and upgraded firing pin and you will be fine. Quote Share this post Link to post Share on other sites

But you'd have to go with a lower that accepts AK magazines. Quote Share this post Link to post Share on other sites
FirearmFrank 2 Posted December 2, 2015 i have run the c-products and asc mags and never had a problem out of standard 10 rounders and 10/20s in my 762x39 AR. Quote Share this post Link to post Share on other sites
fishnut 2,358 Posted December 2, 2015 anyone have any experience with the CMMG mutant? ive been kinda interested in them lately but ill wait until I hear some first hand experience about them or maybe shoot some rounds through one if any NJGF members have one. I like the idea of it but when it comes down to it AKs are a hell of allot cheaper and probably more reliable Quote Share this post Link to post Share on other sites
mipafox 438 Posted December 2, 2015 Supposedly the best way is to buy an MGI lower with the AK magwell. It has swappable magwells. Quote Share this post Link to post Share on other sites
