A friend of mine recently bought a Simmons rifle scope. When he placed the order, the lady taking his information asked what caliber rifle he'd be shooting. He told her "30-06."

When the scope arrives (which he is very pleased with), there is a small box included, marked:

"Simmons model 1476
270-35 Calarbor"

Anyone know what this is and what it's used for?

The item is about 5" in length, polished steel. At one end there is a knurled thumb screw, which backs-out a choke-piece at the other end.

As the screw is turned, the choke piece expands the opposite end.

What is this used for?

Thanks,

Jeffe, that's it.

Is this a bore-sight?

for the life of me, I'm not sure what to do with it?

Any suggestions?

Thanks,

It's an arbor for a bore sighter or collimator. The collimator is used for sighting your scope. The arbor is just the adapter spud for the bore sighter. You still will need the collimator itself.
