My lad bought a tasco #705 for his hunting master 6, its a long gun and he said he wanted a long scope, well this thing doesn't disappoint its 2 foot long, it has a fully floating body that can slide back against a big spring that bears against the front mount, the rear mount can slide also and is held by 2 adjusters and a spring loaded button, its very well made. The dove tails on the mounts are too deep to fit the 11mm rail on the gun, if i ground a mil off each they would fit but i don't want to do that, is there an adaptor out there and if so whats it called.
