So these are redic rare now a days, and I had to buy a 6 pack from http://paintballgateway.com/inbaandhokit.html
for a redic inflated price + shipping, which comes out to about $55. No lie.
These are the legit direct replacement high flow barbs for gen4 timmys and are upgrade barbs for <gen4.
Have 5 for sale, $8 shipped each. I prefer paypal gifted.
Also have some hose for them too.
