What MBA 4 Stock works best that I should purchase for my New VR80 12 gauge shotgun?

Expert Answer
A
Answered by Jonathan D., Gear Expert, from IL, United States, on October 14, 2019

MPN: MBA-4 would fit without changing the buffer tube as it is compatible with both mil-spec and commercial buffer tubes and the VR80 uses a commercial buffer tube.
