Barrel clearance and bipod mounting.

[Dt219]

That’s the mount I have. 1st take the mount off. 2nd tighten the bolts and the holder/nuts like you was going to store it so you wouldn’t lose the parts. 3rd hold the mount either with hand or vise and get an aggressive file or grinder to cut down the threads. Then try it and see if there is clearance. It took me several tries off and on but once done there is enough threads left to feel good about it and enough clearance for the barrel. How I did it anyways
