GOOD news guys, jammed mag is out and barrel is pellet free, I managed to wiggle the mag out, shot the gun to clear the barrel but didn't happen, but lucky for me I do a lot of archery and my outdoor competition arrows are carbon and 5mm outer diameter, so I took the silencer off gently slid the arrow up the barrel and a few gentle nudges cleared the barrel (yes I did take the point off the arrow first ☺ ).... No damage apart from a couple of scuffs on the magazine, still dont like the magazines tho... So a big THANKYOU to all who responded with their ideas, much appreciated....
