It you’re tighting rigidity problems, chatter, or tire of wasting time indicating barrels for chambering or muzzle work – this is your solution!
Say goodbye to:
-chamber runout and setup
-movement during machining.
-Independently adjusts radial and angular runout
-get dialed in fast and dead-on.
Fits both 6-inch and 8-inch face-mounted chucks.
Spider bolts have ball-and-socket aluminum pads that conform to your barrel no need to make sleeves!
Works great for truing actions and bolts too when paired with a 4-jaw chuck and aluminum soft jaws.
