My Standard Products carbine is a Korean import. It had the same type of sling and import marks on the barrel. A dealer offered me 400.00 sight unseen a couple of years ago. Carbine interest is up the dealer was looking for any to sell. I replaced the unmarked Korean stock with a used G.I. stock I picked up . The Korean stock was the same as described above. Rough finish. MIne also has an Underwood barrel and Inland trigger group.
