Hi Peter, I have a couple of No1 Sniper builds to do. And I'd use it in future for the odd job drilling and tapping for a conventional bridge mounts and Field mounts.
If it wern't for the sniper builds I wouldn't bother, but the sniper builds require much more positive and controlled manipulation of the job, and the capacity to rotate the job about the bore axis with precision and repeatability could be very handy.
