GHK AK74u with upgrades + steel bolt

GHK AK74u with W&S steel bolt kit already installed, includes original bolt and magazine maintainence kit. Also installed by the previous owner is a maple leaf tightbore barrel and a TDC hop unit. Front sight is useable but very slightly canted after a dis-and-reassembly, don't have time to take apart again and fix so price is knocked down. The price includes 3 CO2 magazines. Gas mags can be purchased separately for £50 each or had all in with the above for £550 total. Further photos and info available on request. Collection preferred, willing to drive within reason. Postage available if buyer pays fees.
