ive handled it at my local shop. the thing is heavy as F***. seriously. the quality is good but it only has full auto. id like to use a sopmod for a little double tap action ; ). id rather get the marui one and hope and pray that someone comes out with a conversion kit.
one more thing i found out, the G&G, Marui and star m14 mags are not compatible with each other. just one more thing to consider.
