Re: Sling and Oiler for IBM M1 Carbine
The original WWII carbine sling was fairly thin and it is that sling the stock cut was made for. Late WWII and postwar GI slings are made of a heavy weave and much thicker. That makes them very hard to get into the stock. It is easy to solve the problem by using a file to trim a bit off the inside of the stock cutout where it will never be noticed. I have seen people smash the oiler flat, take a grinder to the sling, or even use a big hammer to drive the sling into place because, they told me, to touch the stock would make it unoriginal.
