My marker family + few problems

Regarding the Maverick:

If it has an adjustable bolt, you adjust it by turning the bolt insert to put more pressure on the spring.  They make special tools for this that have plastic tips and allow you to adjust it with the bolt in the marker and the barrel in place, but in a worst case scenario you can remove the bolt to adjust it.  (It is more time consuming to do it this way.)  There were two general types of aftermarket bolts made for the Nelson-based pumps; one required a flat-head screw driver for adjustment and the other used an Allen Wrench.  If you have an adjustable bolt that requires the screw-driver you can buy a long screwdriver fairly inexpensively, wrap it in tape (to prevent scratching the barrel interior) and have a velocity adjustment tool.  If you have the more rare bolt that is adjusted with an Allen Wrench, you will have to find a one long enough to reach through the body with the barrel off.  (An A5 wrench might work, but that's just a guess.)

If you don't have an adjustable bolt, then you will have to try heavier springs.  Most Nelson-based pumps use springs that are the same diameter as stock Spyder springs so you could try one of those.  (It will require cutting down.)

IVG?

"internal velocity governor" the brass/nickel disc in the lower tube with an allen key hole in it, you have to take the cocking rod out to adjust it, turn it in at quarter turn increments until you reach the desired FPS.

the BM reg is very sensitive... you backed it out enough to where thre oring on the screw came out of the seal caught the threads and is now damaged. take the screw all the way out (youre gonna have to take the clip out) and check out the oring. reinsert and screw it all the way in (off) and start over on the chronoing.

mine has the Allen i think, it would be right down the barrel to tell, right?
