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

I bought this for a PSA AR-V 9mm with a Rarebreed L3 selective fire trigger. Although not rated for fully auto, it worked quite well on full FRT. It softens the recoil a little on semi-auto, however, the difference is not like night and day from a heavy buffer and spring, but it is noticeable. I don't know if the $200 price tag is worth it, but I'm keeping it in the gun.
Pros:
  • Delays bolt rearward motion and softens recoil.
Cons:
  • For the money it doesn't make that much of a difference.
Best Used for:
  • 9 mm AR's
Would Recommend: Yes
