    yeah...I think I'm just gonna stick to making other stuff from now on... I suck at making guns!


    You know... I know this is a really crappy gun and all, but it is after all my first Knex gun


    Well, we have a gun that might have been good in 2007, but it is not a block trigger. Use my pistols as an example for good pistols. 2.5*
