I recently changed my 580 series synthetic stock Mini 14 out to a Butler Creek Folding stock. The installation went fine --tight fit and smooth no hitch firing. My BCF stock has two screw mounting holes (one on each side) and I fully expected that I was going to have to order a stock reinforcement plate and associated screws and washers as my synthetic stock did not come so equiped. It only had the forearm plate which I transferred over to the BCF stock. The research I did prior to take down seemed to indicate that this was going to be the case. However, the fit is so tight and operation so flawless, I am wondering if I misunderstood about the necessity of a stock reinforcement plate. Is the stock reinforcement plate a strength issue requirement for the BCF stock or is it ok to shoot without it ? If the plate is not needed I guess I will order a couple of screws to plug the holes unless there are other dress alternatives anyone can offer. Thanks for your time and interest in answering my questions.
