Stealthbomber Posted April 6, 2008 Report Share Posted April 6, 2008 Eh? What? You want advice about fixing a problem you haven't figured out yet? You need to take the front sight off the gun so you can see up the cocking tube. You'll see a screw in the middle of the cocking handle shuttle. Remove it. Remove the cocking handle. Remove the shuttle. Are any of those parts broken? The usual fault is that the front has snapped off the shuttle because somebody's been slapping the cocking handle forward. You CAN fix this simply by rebuilding the shuttle and using JB weld to piece it all back together. When you're done gluing stuff, run a drill (or dremel) into the hole where the cocking handle fits in case the hole's been bunged-up with glue. If you insist on slapping the cocking handle, get a length of rubber hose and shove it up the front of the cocking tube so it just starts to move the shuttle backwards by a couple of mm then cut it off flush with the front of the tube. When you do this the shuttle hits the rubber hose before the handle can hit the side of the cocking tube and stops the handle snapping the front off the shuttle. *EDIT* Having read your latest post, it seems I wasted my time writing all that and the spring guide for the cocking spring is broken.

Please fix your spelling next time... And the thing you're talking about is the spring guide, its just a piece of plastic that helps the spring coil correctly.. Link to post Share on other sites
F1amez Posted April 7, 2008 Author Report Share Posted April 7, 2008 thanx for the advice! i had a look at the cocking handle i saw that it was fine is the spring supposed to be loose on the cocking handle or is there supposed to be something holding it onto the handle??
