Should i post this gun??? It's called: The Bischoff. It features the same shooting system as killerks sr-v1 but, i made my own design that was more compact then the actual sr-v1. With a good rubberband it has a range of 160 ft with the longest barrel i've built (34 pieces of yellow connectors in a row) but the accuracy goes away with 70 ft. It has two handles to give you a more steady shot and if you like, you can take of the bipod. So, what's your conclusion? Post or not???

bardinslayer (author)2013-08-27

bighead5454 (author)2010-07-22

What is so bad about block triggers? The most powerful rifles/pistols i have made/found are block triggers.

H1T4TCH1 (author)bighead54542010-10-08

i like block triggers cause they are very reliable

Wafflicious (author)2008-12-09

lol i went bug hunting with my corner cutter!!! so fun!

Skreetsha (author)Wafflicious2008-12-10

But i didn't do it on purpose. I think killing bugs for fun is cruel even though they are little.

ol987986 (author)Skreetsha2009-10-12

yeah thats so true, even if they are annoying. ishoot little annoying brothers instead.

Skreetsha (author)ol9879862009-10-14

I shoot my stupid neighbour kids.
They are running around like crazy tearing down everything in my garden,and that while they are not even allowed in!
So sometimes when i see them, i grab my sniper, lol.
But most of the time they look up first to check if i'm not there.

DJ Radio (author)Skreetsha2009-10-15

Did you ever get them?  Did they ever steal your ammo?

KnexFreek (author)DJ Radio2009-12-01

i shot my sister in the head with my hell slayer about a week ago, both shots hit her and she cried. i got grounded. but it was only for a day and i ended up sneeking out anyway. thankyou first story bedroom :)

~Z~ (author)KnexFreek2010-02-05

 ONE day?Thats all?

KnexFreek (author)~Z~2010-02-05

 yep. my parents didnt even know what knex was back then. So they thought it was like a little blaster and didnt care much

knex_mepalm (author)Skreetsha2009-08-05

i make paper beetles and paint them to look real and stuff them with some gut-like objects then get a rod, sticky tape some paper at the end of the rod to squish bugs, does this work with killing rats? i found one in my back yard

Wafflicious (author)Skreetsha2008-12-10

lol i only kill those (fake) lady bugs from japan that theres millions of.... and those sugar beetles .. yuk!

An Villain (author)Wafflicious2009-06-04

japanese beetles, or colorado potato beetles?

Skreetsha (author)Wafflicious2008-12-10

Still, i think it's cruel. You may like it but i don't. :-)

thomaswatton (author)Skreetsha2009-01-04

i agree

Wafflicious (author)Skreetsha2008-12-10

no .... wats cruel is ticks... .ticks be cruel.... but you can have your opinion ;)

Skreetsha (author)Wafflicious2008-12-11


blingblong (author)2009-11-22

ewww i squished the living crap out of a spider like all its guts were on the red connector! *shudders* ewwwww
