Mmmk. I have a slight problemo. I would like to get a mag. I was just wondering that if i get the mag from the following link, if i could take off the lil thing w/ the clear grip on it(i think that its a bottom line adapter) and use a C02 tank by having it be a vertical C02 feed (im too cheap to buy a nitro tank)(not nuff money to buy nitro tank, lol). I also would like to know if i should just swap my friends X-chamber that came w/ his Mokal Fokus(great gun, lol, not) and just use C02 as the horizontal feed. (darn, that was alot). Thx for ne feed back.
