Considering buying a used 223; cannot find a model number-letter designation other than Model 10 with a small sp10 stamped on the barrel. The rifle has 24" heavy barrel, accutrigger, and 2 sling and bipod studs in the forearm. Best I can tell from Savage website, the rifle I am looking at is the law enforcement model with 1 in 9 twist. Am I correct? I do have the serial number if anyone can direct me to a site which I could use to find more information about this particular rifle using the serial number.

Thanks for any help.
