Solid QD Adapter

by scott, Verified Owner from VA, United States Written on May 23, 2021
Does what it is supposed to. Locks really hard sometimes to hard to even QD the suppressor. Threading is also deep enough to accommodate a longer than standard thread cut on barrel. Make sure to measure your threads correctly or you will be buying another. BTW I have one of these installed on my custom made 338 LM rifle and bought this one to attach to my .308 DT MDRx.
Pros:
  • Fits perfect
Cons:
  • only 1 small amount of rockset thread coating
Best Used for:
  • the intended suppressor
Would recommend: Yes
