RE: Rifle Basix
I put a Timmney in Ruger M77 and a Rifle Basix in a Marlin 917V. I did have to fit the stock a bit with the Timmney/Ruger. The Timmney offered more adjustment and was crisper. The Rifle Basix was lighter. Both worked fine. The Ruger was a 7 mm Mag for hunting and the Marlin a .17 Mach 2 for P-dogs and fun. The Ruger factory trigger really sucked so the new trigger was needed. However, the Ruger still didn't shoot accurate enough for me to be worth keeping so it got sold. The Marlin was very accurate, even with the factory trigger so the RB trigger really made it slick.
Neither was that difficult to install but I have done trigger jobson many of my other guns in the past. So I wasn't a first timer either.
