First time trying the VFZ mount. I didnt plan on moving my dbal to a diff. Rifle. I bought it 4-5 months ago but only recently tried to install it. Busy with life and work. Idk if it was me or the mount but the c- clip kept that holds the adjustment bolt to the mount kept popping off. Everytime i put it back in (using a 1 oz or less gunsmithing hammer and a roll punch starter) it popped off. Called larue and he took care of me even though i bought it months ago. Sent me a new one quick. The next mount worked like a charm. It aint going anywhere. To install a vfz mount i had my muzzle on the floor so the laser will push forward on the rail towards muzzle. My left fingers pushing the adjustment side up and towards the pic rail as if its in a "locked position". This will help alot. Its like a third hand. This is so the bolt turns easier. My thumb was pressing the RIFLE opposingly. Idk if that instruction will help anyone. It was kind of a PITA. But now i know how to do it. Customer service was no nonsense. Love larue. Have many many mounts. From larue directly as well as second hands from individual sellers. Thanks again!

Great mount but Larue apparently can't send the correct tool for install if you purchase the VFZ version for the DBAL. Once you get the correct wrench or cut down the included wrench to function as an open end wrench, it's a solid product and the best option available.
