Fancy changing my classic length gun to a carbine.Air arms price the cylinder at 16.50,but will not sell to public because of health and safety(compressed air)- which is fair enough.I decided to see if my local gun shop could buy it on my behalf- Im capable of doing the job Ive done a lot of work with precharged guns.He said he could sell me one as he has them in stock,but charges 50 pounds,which Im not prepared to pay.Any body got any suggestions? Thanks Pete.P.S. no problem with the barrel Air arms supply for 45 pounds.
