I bought the Competition lifter from Brownells for my VM TACTICAL-so the fork has been filled in, works flawlessly and my thumbnail is no longer in danger. The one mod I did make was that I filed down the hump so it loads easier and also so be able to unload via the shell catch.
While it is not a long as the CRums modified lifter, I have had no feeding issues that some have had because of weight added to the lifter, or shells not being centered.
The Brownells did work well before I filed the hump down-it was a harder push to load, and I had to cycle the rounds into the chamber to unload.
