About £250 /£300. The good thing is it can be held on a shotgun certificate, provided! That the weapon has ben modified to hold a maximum of three shots, two in mag , one in chamber, anymore and it becomes Section 1. The down side is the NUMBER 5 (Tut, tut , read earlier!) also known as the Jungle Carbine, is the most evil piece of kit to fire. The barrel is shorter with a flash hider, and less wood work. The reson for the open barrel is that in hot humid climates the wood work on the standard N0 4 rifle would swell and contract, touching the barrel which interfers with barrel harmonics altering the zero. Indian built weapons had modified bedding on the barrel to get over this. The result is a felt recoil like a mule. I was, persuaded, into firing one in Jersey, full .303, cordite charged number 7 z cartridge, and took ten minutes to stop whimpering. :-D
