Hey guys, quick question. I just picked up a new old stock 1998 BPS Stalker 3" (minus the barrel) in the box. Has the manual, one choke but nothing else. There is a hole with what looks like a metal sleeve insert in the buttstock for a sling swivel stud. What swivel stud would I need? I would assume the stud just passes through the sleeve and screws into the synthetic stock. Also trying to decide whether to go with the 24" or 26" barrel. Thanks in advance.
