TrickyT's Review of CMMG 22LR Mk4 Barrel Kits w/ Bolt Group

I did a dedicated build, rather than converting .223/5.56. Built the AR15 with everything as milspec, then dropped this in with my CMMG mags and it runs flawlessly. Rings steel at 100yds all day every day.
Pros:
  • Price
  • Fit
  • Ease Of Use
Cons:
  • None
Best Used for:
  • Plinking & target shooting
Would Recommend: Yes
