Worker W0745 Segmented Barrels

Ok, This is the new worker Segmented barrel kit

Because - they're including one segment of each in each kit - that doesn't make a lot of sense to me... I'll divide up a bunch of packs, so you can buy what you actually want. The Full kit gives you a 300mm barrel - I think many want more than that, and want to pick/choose which segments. 

Only the 13mm ID segment has the M16x1 threaded base.
