So here's my problem. First I bought the side rail from KNS Precsion. Perfect fit. Ended up changing them out to the Midwest Industries cause of the sling mount. My question is I'm putting a remote switch for my M300 they give you the Velcro but to much of a perfectionist to do that. So I purchased the magpul switch cover. Well it's to long. But I thought maybe I can use a longer bolt For the front mount of the rail use a spacer and bolt all of it together? What size bolt should I use ? Or what is the mm of the bolt that they use? Any suggestions would help.
