I installed a new barrel in my DMR  and now the bbs are pulling hard to the right past 75ft.  I installed a ASGI 6.01 TBB to replace my mad bull 6.03.

Your barrel and bucking are tilted sideways in the chamber. Remove the barrel, with the hopup chamber still on, turn the hopup all the way up and center it so that it will touch the exact top of the BB (you will have to eyeball it). Make sure the barrel clips in the hopup chamber properly, and reinstall it in the upper.

Ill check that I thought I had it it right but who knows I am the one who took 2 hours to install my first TBB so there is no telling how bad I can mess up a gun.

It's a very easy mistake to make, and a simple fix, I wouldn't sweat it .
