Granted that I have a few Jewel triggers set up in my current DCM rigs, this is going to be the next trigger that will be bought for the next new DCM build.

On this unit, instead of having to take the hammer spring leg up another notch on the star to increase tension a crossed the board if you fail a pull test, you just add tension to the secondary sear it's self.
Plus I'm a big fan of the primary trigger pull having most of the weight, then the secondary needing just a touch once you hit the wall, instead of the other way around.

Keep in mind that there are wilson barrel blanks (like shaw barrel blanks) that are produced into finished barrels by RRA or others, and that no part of either of this is products of Wilson Combat inc.

On the BSA scope, dont waste your time with it.  I have a BSA that I cook yearly on a flat top rig, and really should be replaced with either a SS 16X or 3200 when I get the time.  The only reason that I have not thrown the scope away is that BSA keeps replacing it, and I can get another few months out of the new on until it goes south (will not hold a Zero after a few thousand rounds).
