I still believe you are bias against CVA. You already were condemming the CVA plug even though it is a totally different design in in being toolless as compared to the other 3. The T/C QRBP is a horrible design. That was another reason I choose the CVA over the T/C. This design in a brand NIB rifle could not be removed by hand by myself or the gun shop owner/gunsmith who had to remove it with a set of channel locks. To me that is not QR.
