Key Features to Consider When Choosing a CMMG 9mm Upper
Before purchasing a CMMG 9mm upper, carefully consider these factors:

-
Finish: Consider the finish of the upper receiver, as it affects durability and corrosion resistance. Options often include hard-coat anodizing or other protective coatings.
