15) Lets install the PRO-COMP side covers now. First make sure that the sides of the gun are absolutely clean and free of oil residue. Wipe them throughly with rubbing alcohol. Make sure the receiver is above 68 degrees F, you can warm it with a hair dryer. Measure in from the rear of gun 1-1/8 inch and put a pencil mark, peal the backing off the back of the side cover and align it tipping the top edge into the groove that runs along the gun and laying it down, press it firmly in place. It takes 24hrs for the epoxy tape to cure completely.

16) Now you can install the upper bolt and hammer system. Lightly coat upper bolt, hammer and hammer O-ring with the supplied oil. Slip upper bolt on to hammer link pin, IMPORTANT! ALWAYS DEPRESS TRIGGER BEFORE SLIDING UPPER BOLT AND HAMMER IN OR OUT OF RECEIVER! As you slide system in, with trigger depressed, the detent button on the spring guide must face the flat on the cocking knob, slide the system all the way in, you will have to push the spring guide in and push quick strip pin into place. This my seam a little awkward at first but with a little practice you will have it down. Now you can cock your gun by depressing the trigger then pulling out cocking knob until it stops, then push knob in, it will click into place. To decock gun pull knob out, while holding knob out depress trigger and let knob down slowly. Dry firing is not recommended it can cause unnecessary wear and possible damage. ALWAYS HOLD TRIGGER DOWN WHEN COCKING, DECOCKING, FIELD STRIPPING AND REASSEMBLING YOUR PRO-COMPv.3, IT KEEPS THE TRIGGER SEARS FROM DRAGGIGN AT THE WRONG TIME THAT CAUSES UNNECESSARY HAMMER GUIDE AND O-RING WEAR!

17) Now the fun part! Install feed adaptor, barrel and barrel plug. YOUR BARREL PLUG IS YOUR SAFETY, ALWAYS USE IT! Cock gun (Don't forget to depress trigger) push knob in and install air supply. Go ahead and fire about five shots, remove upper bolt and hammer, inspect hammer guide (Delrin part of hammer) to see if trigger sear in scraping the guide if it is sand it a little more, there should be no scraping at all. Double check it after about another 50 shots. You now have a super high performance VM68 that is know known as a PRO-COMPv.3 and it's ready to rock!

18) ALWAYS chronograph your airgun before you play! See tuning your PRO-COMP in this manual for tips on setting your velocity,

19) ALWAYS REMEMBER TO USE YOUR BARREL PLUG FOR YOUR SAFETY AND DEPRESS TRIGGER BEFORE REMOVING OR INSTALLING UPPER BOLT AND HAMMER.

20) If gun goes full auto, Just pull out cocking knob!
