Modified Crosman 760, 4.5 to 6mm
Posted: Sun Nov 06, 2005 3:30 pm
I found my old Crosman laying around a couple days ago, and thought, "hey, I don't have an airsoft gun anymore.." So I decided to modify my BB gun, from its 4.5mm BB barrel, to a 6mm airsoft barrel.
I simply took it apart, took the barrel out, and with the aid of some duct tape, put in a barrel from my broken shotgun.
The 760 has a underbarrel grip, which you pull down, then push back up, to pump it, It takes about 10 pumps to charge it to full power. When I shot a 6mm BB out of it, I hit my front door, which is metal, and it shattered my BB. I guessed it was going about 500+ fps. But I dont have a chrono to back that up.
So I decided 3 pumps should do for airsoft, and it only shot around 200-250, conisitently. So thats a good speed for airsoft.
I actually put the front blade sight from my original barrel to help aim the thing, and the muzzle thread protecter thingy from my mac-10.
From 20 feet away, it would be a devastating weapon in airsoft, 10 BBs at the same time....
Now that I've talked enough, time for some pictures, sorry for the bad quality, I dont yet have a good source of income.
--The whole gun--
--Through the rear peep and front blade sight--
--The target, 10 BBs, 20 feet away--
There it is, please leave your comments...
