okay i was wondering if you could do a 555 timer knife for cod4/5 just seems like a cool idea and why do some guns in cod5 shoot slower than others with rapid fire... like i use gherwer or whatever its called and it shoots slow and unreliable then i pull out m1a1 carbine and i shoot about 6-7 bullets a sec no cap is there a way to fix this im using the radioshack brand 555 timer with momentary switch
