Best long range knex gun?

Hey i just want to know what knex gun shoots the farthest that isnt overkill on pieces. Any recommendations?  Thanks!

Well srv2 is good but takes a little to many pieces And then theres the nar or not a rectangle on knex innovation.
my TR series will shoot over 300ft w/ fin ammo
Alright here's what you do, go to and go to the instructions section and build the NAR stands for "Not A Rectangle." This gun can get up to 300 feet using fin ammo, and about 100 feet with Oodammo.
