This Bear Creek Arsenal BCA15 is a used semi-automatic rifle in 6.5 Grendel with a 16-inch barrel topped by a quick-detach flash hider, serial number 55555, of modern production. The bore is excellent, the finish shows light marks and overall condition is very good. It wears an M-LOK handguard with a Picatinny accessory rail and an OD green FAB Defense collapsible stock, and it comes with a Pulsar Trail XP38 thermal optic, the optic's original case and a sling.

For a Montana hunter, 6.5 Grendel in a 16-inch rifle is a practical deer setup, and FWP sets no caliber or magazine limit for game animals, so a semi-automatic rifle is lawful for the 2026 general season of Oct. 24 to Nov. 29 outside the weapons restriction areas that allow only shotguns, muzzleloaders or traditional handguns. Firearm hunters must wear 400 square inches of hunter orange above the waist. Check the current FWP rules for your hunting district before carrying the thermal optic afield.
