A very nice chap off here sent me one of these to play with. I did not try it before the strip and the action was already out of stock but here goes. Undo the 2 front stock screws on the underside of the fore end and the two screws on the trigger guard. To remove the trigger guard you have to pull the safety lever on the trigger unit down and wangle the guard off. Take the action out of the stock and watch out for the piece of tube that sits in the stock near the stock bolt. replace it now so you wont forget it. Undo the barrel pivot bolt and lift out the barrel and breech block, complete with the cocking arm which is rivetted. Watch out for the 2 plastic shims. If you want to remove the plunger and its spring, you will need to drift out the sleeve that the barrel pivot goes through and the shims go on. clean, grease and replace this now. There are two pins at the rear of the cylinder that hold the trigger unit and end cap. Drift these out and remove cap and trigger unit. The next step is VERY IMPORTANT-----There is a scope arrester on the scope rails---you need to undo this screw before you attempt to strip the gun further. Once you have done this, get your bit of tube etc to push against the guide/block that the stock lug screw goes into. When you are pushing against this block, use a spanner to undo the lug and when it is undone, release the pressure on the block and the block/guide,mainspring and piston can be withdrawn. Go to part 2
