well if you insight to the G3 i'm a die hard G3 fan and if you live in calgary you can get on the JOC. i would go with the G3 why cause with a 700 budget on a gun i would get a CA full metal G3 its worth the money that G3 is so strong i could beat silly with it. another reason why to go with the G3 is because its got more upgrade options compared to the FAMAS.
here what i did to my G3 after a few 100 bucks got put in to it. my custom built HK G3KA4.
