My mate has got a standard one and a Black Arrow version (barrel weight and scope).
He shoots them very competitively in pistol HFT.
I had one but I couldn't get on with the trigger, the adjustment only seemed to alter the pull weight and I could never get it to the point where I was sure exactly when the shot was going to go - there seemed to me no definitive 1st or 2nd stage. Might have been just that one gun I s'pose?
They seem well enough put together, although I have noticed on the later examples I've seen (brand new) in the dealers that there is a distinct colour mismatch on the metal parts, I think some is anodised and some blued and they don't agree.
