As a 2h xbow, it's a solid weapon independently from the special.
EDIT: reading skills just went down a whole lot. Thanks Jamoose for pointing that out.
To give a correct answer: the taunt effect on mines is really useful, but the problem is that the cooldown is kinda high and Spike Trap itself isn't much of a good skill., because of the delay between cast and explosion. Until there are no aditional items that create some good synergy with the ability itslef, Chanon Bolter is no different form standard 2h xbows.

OT: No idea, i've always wanted this xbow so i can test it but never had it drop for me so that's kinda sad i guess.
