get a shorter outer barrel and a 225 to 275 inner barrel
Ideal would be a short raider top receiver but problem you may have if using FireHawk 110mm barrel and "maybe" the 225/233 short Raider barrel on L Raider
is ya cylinder port would be way out on the ratio - ya using say a 363 cylinder for a 110 to 233 barrel - port at halfway rather than 3/4 of cylinder
So unless you change cylinder/port when using a shorter barrel you may get odd fps
maybe look out for a cheap bollox'd Raider S to overhaul & tweak, only problem is G&G are a little too damn reliable so finding a moody one for a good price may be very tricky
fire the loud bitch thing - it can get on ya nerves a little all day - but suppose is what ear plugs/defenders are for
the dust cover drops down properly unlike Raider's pull down one - think the port G&G used in cylinder isn't quite 101% correct for such a short tiny barrel but that is yet another gun I gotta look into - think it was a 225/233 port so fps was out a bit when i serviced mine - but still a fine sexy beast of a gun
