I have the prior Mutant pistol in 7.62 and it shoots so smooth/soft and is tack driver. Shoots softer which allows for faster follow ups. Shoots a little softer than my Gen 2 Sig 556r AK. 15 adjustable settings on the newer DI version and proper side charger versus the AR charging handle on the CMMG. I use to have CMMG 9mm and it was also an amazing shooter.. they build quality and the 300 level is kinda one and done without any upgrades.
