Blu Barrels - 12.7mm ID

Bringing some more of the Singapore options.

Blu asked if I wanted in on the next run of his barrels - Cut, anodized, and threaded? Shut up and take my Money Blu!

So these are 12.7mm ID - that's a lot tighter than the usual options. This may be problematic if you're using a pusher that seals directly into the Barrel (I do sell Dash 011 o-rings - that might let it work... it might not). 

Tighter barrels - more crush on dart - dart seals better in the barrel... But more drag.
