I never bothered with them before, but one came on a recent rifle purchase, and I like it! I wish they still made them, it seems like a quality optical sight at a reasonable price (when they made them). The scope is a Nikon ''Buck Master II, 4-12X''. The rifle is a Ruger M-77 Mk. II Hawkeye chambered for .338 Winchester Magnum. It wasn't exactly what I was looking for, but for the price and all the ''goodies'' that went with it, I'da been stupid NOT to have bought it! Rifle, (like new) scope, loading dies, bullets, brass, and loaded ammunition all for about $500.00 less than the rifle alone is worth. Sometimes God smiles on us. (BTW, I paid the man what he wanted for the outfit, he said he wouldn't haggle on the price-I didn't argue)
