BKO Reg Adjustments
This question seems to be asked often and most of the time all you have to do is read the manual, but here it is anyways.

If you have a 2003 version of the BKO you will want to adjust the HPR, the long foregrip looking thing in front of the trigger guard. To adjust it you will simply turn the screw at the top of the reg to the left, as you are viewing it. This will decrease the pressure. Since the marker is over pressurized you will want to turn it out until you see at least one thread showing out the side of the reg housing.
Next you will want to back out the screw on the LPR as well. This is located between the HPR and the Trigger frame. It is a small cone shaped item with a screw in the center of it. You will turn it to the left while looking at it. With one screw showing we can now start on adjusting the regs for proper operation.
Go back to the HPR and turn the screw at the top of the reg in, to the right, until the HPR reads 200 psi.
Now goto a chrono and adjust the screw in the LPR, turn it to the right, until you reach your desired FPS setting.
If you have a 2004 BKO then the LPR will be located directly below the barrel. It will have a slot in it that a quarter fits in quite nicely. You will do the same adjustment process but you will need to turn your HPR up to 275 psi and then adjust the LPR until you reach your desired FPS.
There you have it, step by step.
