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???

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

H1T4TCH1 made it! (author)H1T4TCH12010-10-08

i like block triggers cause they are very reliable

Wafflicious made it! (author)2008-12-09

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

Skreetsha made it! (author)Skreetsha2008-12-10

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

ol987986 made it! (author)ol9879862009-10-12

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

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.

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
