They are made of brass. Real easy to "fit" Just remember these LMG's weight 20 plus pounds and are gas operated. Recoil should be minimal. I plan on using it. I have 5 days to get it to fit.I don't think I'd do anything to "make a scope fit" and I darn sure wouldn't shoot the gun with it in place. The eye relief is so short that without a soft rubber eye piece you will be needing stitches.
There was one for sale somewhere? I saw it. No guarantee it is for a 99. But it is for a LMG. Probably early issue.Anyone know if there was a T-99 LMG scope case made in just leather?
