I dont like this "crossbow", but seeing how this was posted in the early days of knex, im giving it 1.5*

DJ Radio (author)DJ Radio2008-11-07

if it was posted in 2007 or something like that, it would have been 0.5, no offense

iKill (author)DJ Radio2008-11-08

this gun is worse than a block trigger i know that but like you said different time different standards

DJ Radio (author)iKill2008-11-08

yeah, at the very least, its a bow

supercerealmonster77 (author)2008-02-06

, not bad i kinda liked it im havin lil troble shooting the because the 2 green connectors keep slidiing together

try adding spacers, i built this when i had maybe 200 pieces i was limited to about 5 spacers in my whole bucket

supercerealmonster77 (author)2008-02-07

Dbfb05 (author)2008-02-07

iKill (author)Dbfb052008-02-07

iKill (author)sugg222007-10-25

look at when it was posted... it was before most guns on this site

iKill (author)iKill2007-10-25

in fact its the 13th thing tagged with knex on the site... and some aren't even knex or guns

sugg22 (author)iKill2007-10-25

true, but people have been building knex guns with triggers for years, so...

Trogador (author)2007-10-06

Jeez, the instructable has more parts than the bow has pieces (not counting the rubber band; I don't consider those pieces)!! XD! Seriously, though, this is a great example that size doesn't matter. Great bow!!!!

ojochris (author)Trogador2007-10-13
