need help on bb sniper

[singularity]

i want to make an accurate small caliper pneumatic bb gun, i have made many in the past and just recently made a vortex bbmg, but none of them are accurate or long range. the first few i ever made i used 1/4 pipe from the hardware store, when i made my bbmg i used a 5/16 brakeline (it shoots like a shotgun) any suggestions on barrel or other ways to make it accurate? i want to make it clear i dont want to make an automatic gun, im tryin to make a sniper

P.S. check out my website http://home.comcast.net/~irwinner/home.html

Check out the metal tubing on McMaster try using some that is closer to .177 inches.

Go to a model shop/hobyshop and they have tubing in brass and alluminium piping from 1/2 millimetre to 1/2 inch.
