Note: Rifle shown has Anschutz match sights. Stock rifles come with Gamo match sights; it is not allowed to replace these in Sporter Class rifle competition.
These instructions are for Gamo rear sights:
Since its release in 2001 there have been minor variations in this model:
Butt stock was longer, and the cheek piece height was not calculated to work with the Gamo sights (it was too high). The factory rectified this by retro-fitting a set of riser blocks. It is only permissible to use riser blocks on these early rifles for Sporter Class.
Trigger shoe was metal.
There was no clamp around the front of the fore-end and the barrel. There was also no cutaway in the fore-end showing part of the cylinder.
Butt stock could be removed with a flat blade screwdriver.
Butt stock was altered more to junior specs, and the cheek piece height was corrected. However, no butt spacers were supplied with the rifle to extend length of pull for bigger kids.
Trigger shoe changed to plastic. This was a problem for a while; breakages were common. The factory then supplied a larger headed screw to spread the load - breakages are now rare.
The fore-end clamp was added, with new styling to the woodwork.
For a short time the muzzle cap, or front sight base, was plastic. This could split if the locking set screw was over-tightened.
The lock nut for the butt stock was changed to a slotted nut, requiring a special tool for removal of the butt stock.
Pressure gauge on the end of the cylinder was changed, no longer giving the red graduations of over 200 BAR or under 120 BAR.
To adjust trigger to 1 ½ lb:
|Ensure rifle is unloaded. Remove cylinder.
Remove the fore-end screw with allen wrench. You can then remove the fore-end forward.
|Barrel assembly can be removed (if required) after loosening the two M5x6 socket head screws in the front part of the receiver.|
|The butt stock can be removed by removing the side screw and nut through the bottom of the pistol grip (as shown). For early model Valiants a flat bladed screwdriver is required. Later models need a two-pinned driver to remove a slotted nut. Pilkguns carries this tool, or you can make it from a 7mm (or thereabouts) nut driver ground to fit.|
1. Screws #18 and #27 may back out. This will cause a drop in velocity as the end of the cocking screws foul the inletted part of the stock (shown in photo on right). If this should happen, send rifle back for repair.
2. Screw #61 may fall inside the action (referred to in Trigger Adjustment 1). A trigger spring will also be dislodged. To retrieve this screw and spring you should remove the trigger guard (screw #59). When replacing spring there are locating tips on the sear and the screw to hold it in place.
3. If the trigger has too much takeup spring #68 may come loose and the trigger will no longer work.
4. Part #1 (front sight base aka muzzle extension) is sometimes made of plastic. If you try to over-tighten the set screw holding it on the barrel it will strip out or break the molding.
5. Trigger shoe is plastic, and may break if the clamping screw is over-tightened.
6. Butt stock screw has been changed to a spanner nut that takes a special tool to remove. We have a special tool available if required.
7. This gun is not pressure regulated, so it is unwise to adjust the velocity (normal velocity should be 560-580 fps). By increasing velocity there will be a wide variation in pellet speed, plus the number of shots will drastically drop per cylinder.
