THE GAS RAM SHOULD BE COMPRESSED AT LEAST 3MM AND BE INSTALLED CENTRED IN THE RIFLE ACTION

IF YOU ARE UNSURE IF THIS RAM WILL FIT USE THE FOLLOWING METHOD

*REMOVE THE SPRING AND GUIDES
*MOVE THE PISTON AS IF THE GUN IS UN COCKED AND MARK WHERE THE TRIGGER SEAR WILL CATCH THE PISTON WHEN THE GUN IS COCKED
*INSTALL THE TRIGGER UNIT
*MOVE THE PISTON TO THE REAR AS IF THE GUN IS COCKED MARK THE POSITION OF THE SEAR POINT
*THIS IS THE STROKE OF THE PISTON
*CUT 2 WOODEN DOWELS ONE 260MM AND ONE 150MM
*MOVE THE PISTON FORWARD TO THE UN COCKED POSITION AND INSERT THE 260MM DOWEL REASSEMBLE THE END PLUG AND PIN
*NOTE HOW WELL THIS FITS ALSO REMEMBER THE RAM CAN BE COMPRESSED 3MM BUT YOU WILL STILL NEED 100MM OF PISTON TRAVEL
*MOVE THE PISTON TO THE COCKED POSITION AND INSERT THE 152MM DOWEL AND INSTALL THE END CAP AND PIN
*NOTE HOW THIS FITS ANDAND HOW MUCH SPACE IS LEFT. THE CLOSED LENGTH CAN NOT BE EASLY CHANGED
*AT THIS POINT YOU WILL HAVE A GOOD IDEA IF THE RAM WILL FIT AND WHAT ADAPTORS WIL BE REQUIRED
I GENERALY MOUNT THE ROD END IN THE PISTON WITH A 3MM SPACER TO PISTON ID WITH A CENTERED 2MM DEEP DIVET FOR THE RAM ROD TO FIT IN
FOR THE OTHER END I MAKE A DELRIN SPACER JUST UNDER PISTON ID TO FIT IN THE RECESS OF THE END CAP SEE THE LAST PHOTO FOR AN EXAMPLE (PARTS SHOWN NOT INCLUDED)
