| Level 10 will work fine - no problems other than the usual tuning.
The ULT isn't recommended for Classic Valves, but it will work. The main issue is it makes short stroking the trigger VERY easy. No milling is required, but you usually need a good bit of shims.
My advice - if you want to lighten the pull with a Classic Valve, get a RT On/Off. They work fine and drop the pull from 4lbs to 2-2.5lbs. |
