This may be a silly question. I am reading some documents on tuning techniques for the Marauder and one section refers to the transfer port. Here is a snipet from the doc I am reading. What and where is the transfer port adjustment on the Marauder.
*******
A) Hammer Throw (HT): With the gun assembled, adjust the hammer throw to the longest throw position. This is done by inserting 1/8" allen wrench through the spring, into the hammer and catching the Hammer Striker. Then turn counter clockwise until the Striker is fully retracted.
B) Hammer Spring preload (HS): With the gun assembled, adjust Hammer Spring preload to minimum tension. This is done by inserting the 3/16" allen wrench then turning counter clockwise until the Hammer Spring tensioner is fully retracted into the air tube butt cap.
C) For the Marauder rifles, fully open the transfer port adjustment by closing it (fully clockwise) and then back it out 4 to 4.5 revolutions (counter clockwise). For the P-rod, if possible, replace the transfer port but change the ID to .110" or smaller. It is rare that a PCP needs a transfer port larger than .110 to achieve 20 ft lbs. A Transfer Port that is large enough to give you the velocity you desire but no more will give you a flatter velocity curve. If you want a really long, low power string, very small tranfer port is one way to achieve this.
