Gene's Review of OpticsPlanet Exclusive Maxim Defense Industries RDB Roller Delayed Blowback System

With so many variables on a 9mm AR , it's always nice to have another tuning option that can reduce reciprocating mass. The felt impact of the carrier is felt less with a bit of weight reduction I n.
Pros:
  • less weight
Cons:
  • Can be a pain to remove from the buffer tube
Best Used for:
  • PCC
Would Recommend: Yes
