The scar 17 has a little rep for being hard on scopes. I am running a Elcan 1.5-6 on mine with a thunder beast suppressor. What I would like to use is the uns 30 clip on with the elcan. I am concerned that the recoil might be to excessive for the tube and damage it. Mainly shooting hogs at 100-150 yds so the 6 power will work well. Just not sure what kind of recoil mitigation the 30 has. Looking for you guys expert opinions.
