Or you could say the 68 cal Impulse, which is produced by the guys behind 50 cal, is, for some reason £200 more expensive.
Considering both guns would cost pretty much the same to make:
Its more likely they slapped £200 on to the price tag to make 50 cal look more attractive.
For all the other manufacturers, who dont have a vested interest in pushing 50 cal: The demand for 50 cal would need to be there before the guns become compettitively priced.
From the evidence out so far, 50 cal looks great for punter days but not for 'competitive' paintballers.
I dont think this pricing scheme will be followed by anyone else.
