Free: Contests & Raffles.
Old fullfields and Signatures actually have pretty decent optics. If you have a range toy that needs a decent scope to shoot small groups, or need a scope for working up loads for different rifles, I wouldn't be too hasty to be rid of it.It should have a lifetime warranty too. Despite what you might read, I sent an OLD signature 6-24 in recently and received quick turnaround and no cost for a checkup.
