Regulating the Blaser BBF/BB/95/97
This info was furnished by Andrej, at BlaserUSA. Translation of German document by Dom, layout, and assistance by GBE, and Chucky.
Translation of the second document.
Regulating the Blaser BB/BS 95/97
Steps:
1. Sight in the lower barrel just like you sight in single barrel weapons through scope or iron sight adjustments.
2. Take a shot with the upper barrel.
3. Adjustment to the Upper barrel:
For Shots Hitting High:
a. Loosen Setscrews a and c.
b. Turn Screw C left (this moves the screw away from the barrel, ¼ turn equals about 6cm shot movement at 100 meters distance)
c. Turn Screw A right (this screw pushes the barrel down tight)
DO NOT USE FORCE!
d. Loosen Screw A about 1/16 turn. The Barrel should not be held tight between screws A, B, and C!
e. Tighten setscrews a and c.
For Shots Hitting Right:
a. Loosen Setscrews b and c.
b. Turn Screw C left (this moves the screw away from the barrel, ¼ turn equals about 6cm shot movement at 100 meters distance)
c. Turn Screw B to the right (this screw pushes the barrel to the left)
DO NOT USE FORCE!
d. Loosen Screw B about 1/16 turn. The Barrel should not be held tight between screws A, B, and C!
e. Tighten setscrews b and c.
For Low Shots, For Left Shots:
See instructions above, but use opposite turns of the adjustment screws.

Re: Regulating the Blaser BBF/BB/95/97
The rubber is purely asthetic. So don't worry about it. Not sure what the fat means. You slide it in and it clips on. To get it off you insert a small screw driver to lift the steel clip out of the slot and slide the rubber out.

Fat is an awkward translation for lubricant.

Does someone know what tool you need to fix the setscrews b and c? Thanks.

Re: Regulating the Blaser BBF/BB/95/97
Should be a small flat head screw driver. But if you have a double or bergstuzen and the barrel is approximately centre you I have been able to get it regulated using coarse adjustment behind the stock if you wind very carefully 1/8 turn with an allen key.

Re: Regulating the Blaser BBF/BB/95/97
All three adjusting screws, and the locking set screws, on my recently manufactured BBF 95 are metric allen head. Don't recall the sizes.
If Blaser have replaced slot heads with allen socket heads, that can only be good.

They are for the bbf combination but not for the sleeved barrels ie double or bergstuzen.

Re: Regulating the Blaser BBF/BB/95/97
Many thanks, I have a 9.3x74 double. I noticed that b and c setscrews are not fixing the B and C screws. Does anybody know what allen key size is needed? The setscrews are not visible, I assume an allen key is needed.

Re: Regulating the Blaser BBF/BB/95/97
You need to remove the rubber insert to see the B and C set screws. The allen keys should be 0.9mm.

Re: Regulating the Blaser BBF/BB/95/97
Oj, hjälp!
So, let me get this right - there are 6 different screws. In that diagram they are labelled A, B, C (which would be the adjustment screws) and a, b, c (these being the ones on the front, which are the set screws?). Clear as mud so far...
I don't understand instructions "c" and "d" - You turn the screw to push the bbl in the direction you want - and then loosen it 1/16th of a turn? I'm sure this makes sense once you have done it and the instructions start to make a bit of sense.
Is it necessary to first remove the rubber insert? I guess so from Chucks post above.. I don't have the rifle in front of me, just thinking about this nightmare ahead of time...
