Rock River two stage trigger (probably should have upgraded this, though it's not bad and should become a bit lighter)


I used the JP spring set with RR trigger with good results.

What are the lightest scopes out there


The Leupold ultralight are good quality light weight scopes. The 2-7 is 8 ounces I belive and 3-9 maybe one ounce more.

I used aero ultralight 1" extended mount. It is 1/2 the weight of the closest alternative. Three ounces! You do have to be careful and patient to master how the scope will rotate as you tighten the mount. Not for the mechanically challenged.
