The barrels are really nice.... 4" aluminium backs and a 10" carbon fibre front.
Extremely light and pretty damn durable. The kit is one, if not the, cheapest carbon fibre kit on the market.
The accuracy is amazing! and the range of backs that are included make finding the crucial paint to bore match easy.
They are quite cheap at the moment so get one whilst you can.
