BB trigger pull



Log in to see fewer ads
Is there a relatively straightforward way to increase the trigger pull on a BB? I need to get it over 2lbs for NRA rules.

I'm an experienced machinist, and have done many (American) triggers over the years, but have yet to pull apart the Russian.

I'd rather not have to pull the action out of the stock, but can and will if necessary.

Biathlon Basic Trigger Adjustment

This is from the factory manual - hope it helps.

Well, yes, there is. But you will have to pull the action.

Read this thread.

This is the way I do it.

If you have a trigger pull gauge you can test the pull before you reinstall the trigger group back into the receiver.

That's slightly weird--Mjoollnir wants to get the pull weight over 2 lbs., but the manual says to never adjust it BELOW 3.5! Does this mean that BB's come from the factory with settings below the minimum recommended? Or that it's a pre-owned gun and the previous owner set it that way...

More like a factory caution issued because of the potential liabilities wrought by a litigious society.

Mine came, new in box, with a pull of about 1.125lbs (which is why I bought it btw). I expect aom22 is right about the legal covering their butts theory.

Well, it would if the Basic had the adjustable trigger. Only the full Biathlon model has the neato trigger. But thanks.

Thanks. That looks familiar. I don't have the rifle in front of me just now, but I recall a screw on the bottom of the trigger mechanism that apparently holds the safety bar. Adjusting it didn't affect trigger pull, just made the safety non-functional.

Guess I'll have to get the rifle out, pull the baseplate and take another look.
