halfblock lightning, newb. General q's and tuning q's

[ultima_subzero]

Hey guys I just bought this:



I was wondering if you can tell anything about it from the picture besides the fact that it is halfblocked. Is it mini'd or anything?

Also, how do I go about tuning this thing. How far does the screw in the back of the gun go in (ivr?).

I am not sure of what hammer it has, but it seems to weigh between 30-35 grams. I am going to be ordering a hammer slug, along with a CCM hammer spring because I want the lightest pump action possible. Any suggestions?

Yes it is minied, but I believe all superbolts are minis. On minis, the ASA screws into the frontblock or pump block rather than the body.

The IVG can be anywhere from the middle to the back ideally, you want adjustability but also a low mainspring weight.

I'd say you are well on your way. Just sweetspot and rock it from there. Have you tried to put that tornado in this body? Sometimes Tornados don't fit in superbolts...
