if you're shooting a DM4 i have no idea why you'd care about a spyder. but, I think that the DM4 is cocker threaded, and they make spyder threaded - cocker threaded adapters. meaning you can screw a spyder barrel into a cocker threaded gun.
the answer is, no. you cannot do what you have said unless you buy a modifications like outlaner desceibed. and i remember you youre the guy that has like $2000 dollars and cant decide which gun to buy.
Dont use adapters. Most guns use certain threads, autococker threads are very popular, they're on timmys trixies, new bushys, old defiants, cockers, basically every good gun out there. Spyder threads only work with spyders, tippys with tippys, and such.
