I have a Yugo underfolder with the Grenade Launching site on top. My AK has an Ultimak Rail. I want to use the space on the rail covered by the grenade site in the down postion. Part of it at least. Since I've owned it for a few years and haven't launched any Yugo grenades I don't think I'll miss it. Has anyone modified that site but shortening it. I know it can't be removed completely because of the gas switch but can it be cut down w/o affecting function? Looks like it wouldn't matter but I wanted to see if anyone has actually done it already. The metal is very thin where I propose to cut and grind it down. Thoughts?
