this is my truely semi auto knex gun you pull the trigger i shoots. some of u will look at it an say it isnt semi automatic but it is. it shoots blue rods. if i get enough ppl that want instuctions i will make instructions. this is my design the only thing that is not mine is the bi pod. so here are some pros and cons.
doesnt need any abnormal peices
shoots 25 ft depending on ruberbands
have to take finger off trigger 2 let it lock back inplace
only holds 6 rods
handle isnt very study
