Remove the stock.
On the rear of the receiver locate the hammer adjustment bolt. It's the rear facing,flat blade style bolt.
It is locked in place with a set-screw thats accessible from the bottom of the receiver. Just back the set-screw out.
The hammer spring can now be adjusted. Clockwise to increase velocity and,of course, Counterclockwise to decrease velocity. Do Not make adjustments with the rifle cocked.
You will need a chrony to adjust velocity to the rifles preferred pellet.
When your target velocity is reached,make sure to tighten the set-screw to eliminate movement of the hammer spring adjusting screw/bolt.
Hope this helps You,
Mike

Does the hammer have much adjustment? After one full turn clockwise the velocity does not increase much, and after one full turn the velocity started to drop?
