I have recently purchased two. One is a 26" VR Special Purpose and the other is a 28" VR Premier. The Premier will function most of the time with 2 3/4 dr. but not every time. The special purpose will not function at all. That is, the bolt will come back a little over halfway.
I am aware that they function well with Hv loads and probably will function well with the black, cheap Remington loads.
However, I am looking for the way to adjust/gunsmith the special purpose to handle the low velocity loads reliably. I have torn the special purpose ALL the way down so I know how it operates. My first inclination is to cut or switch out the spring in the stock. I am aware that I may have the gas ports opened ever so slightly.
Does any one have firsthand experience in this?
