John's Review of CMMG 22LR Mk4 Barrel Kits w/ Collar

Using this for a 22LR build, barrel and collar are as advertised. Got barrel and collar for a great price at Optics Planet. I am using Spike's Tactical for the rest of the 22LR conversion which works fine with the CMMG barrel and collar.
Pros:
  • Good quality and fit.
Cons:
  • None
Best Used for:
  • Being able to use cheaper 22LR ammunition when shooting an AR for recreation
Would Recommend: Yes
