Anything other than the CMMG is only an approximation of your actual AR. The CMMG lets you use your own AR. Same everything, literally everything except less recoil and shorter distance accuracy. I used the CMMG in my AR for Steel Challenge for a year before buying a proper .22lr weapon. It was more than adequate in accuracy whether it was my AR with ACOG sight or the one with a Leopold 1-6 variable, dialed down to no magnification. For those who don’t know Steel Challenge the stages include 10” round plates out to 18 yards and 12” round plates out to 20 yards with larger probably 18x24 plates at distances up to 35 yards. Never had an accuracy problem whether shooting CCI Minimags 40g high velocity, Remington Golden Bullet or Aquila high velocity rounds.
