So are we saying I can shot the 4.6 through my 5.7 MK … and vice versa I don’t like the new straight 5.7 mag and my 5.7 dump ammo (defect) can I load 5.7 rounds through Cmmg 4.6 40 round mag … btw I plan on shortening my original 5.7 mag to 25 rounds and cut the feed spring
Stick a FRT trigger in that bad boy.
Told you it should work fine since the FsN Mags feed 4.6 perfectly.
Interesting, I just bought a cmmg ar15.
Put a mask on it!!!
How's the recoil on an AR in 5.7 or 4.6 compared to 556
