My friend at Sunshine Airguns asked me to tune one up Saturday, got to it today. Gun shoots 780 fps with Webley Mosq pellets out of the box. Gun has a good balance, the blue crosshair scope is nice, see how long it lasts as this gun has a decent kick to it! Snappy, quick firing cycle, a bit of twang...not really to bad. Beast to cock! Not for plinking unless your the Hulk! So let's get inside........
Hmmm, the stock screws don't want to come of...what the? They are reverse threaded!...ok, trigger guard screws, no problem. Pull out the action, looks good...no hidden rust or rough spots. The trigger has some kinda beartrap thingy..interesting. Take out the pin for the safety lever...that's off. Take out the trigger blade pin, ok. spring for the safety, ok..... take off the sear lever pin...shoot! where'd that spring come from?!?!?! ok, goes between the sear lever and the piston hook...how the heck do I get it back in? Any way, took apart the rest of the trigger parts, the beartrap. Put her in the compressor, tapped out the receiver block pin, unscrewed the trigger housing bolt....and out she comes. The rear block is plastic with an integral spring guide. How you gonna make a custom for that? it has a synthetic washer topped with a metal washer against the spring. Spring is coated lightly with a blackish grease, smooth and well made with the ends nicely finished...very even. Piston is a snug fit in the comp tube, little on the tight side...break in will be nice. The piston is stainless or chrome plated,long too! The seal looks great, no cuts in it at all...not too hard or soft... clear yellow. There is a massive tophat of the chrome/stainless metal like the piston. Almost 3" long, the top diameter is approx. 3/4", for about an inch and the rest is a pressed in shaft of almost 2" long at about a little less than 1/2" diameter. The barrel is held in place with a large pin, no screw and nut arrangement ala HW. I noticed AFTER I took it out that one side was serrated (is that the term?) to lock it in place going out right to left (gun in shooting position)....dumb me went the WRONG way! The breech block has a flat washer on the left and a concave spring washer on the right. No cocking shoe. Cleaned the barrel and the comp tube and trigger parts. Polished the spring ends and the washer and the tophat. Greased and tarred where applicable and ptu it all together. Got the pesky spring in the trigger and tested the reassembled trigger before I put the mainspring in ( getting smarter brah!!) Put everything back together, wipe down, action in the stock, loctite the screws and good to go! FORGOT PELLETS!!! DUHHHHHHH! Can't even shoot one shot! Tomorrow, chrony and check the firing cycle. I am expecting less torque, smoother shot cycle. Twang should be a little less but I'm not expecting much due to the loose spring guide in the rear. For the price, the gun is a good bargain and pretty decent on the inside. Thinking of getting some fiber washers to shim the trigger. The seal is what got me, how many of you have pulled one out of a bargain gun cherry with no nicks or cuts? Says a lot about the interior finish I think.
