The 870 Magnum receiver, identified by the 'M' serial suffix, is rated for 2 3/4" or 3" shells when paired with the appropriate barrel, and this build provides that flexible chambering. The gun is configured with a 20 in barrel for maneuverability and a brass bead front sight for a clear, straightforward aiming reference.
The barrel is threaded for screw-in chokes and currently wears an extended, ported breacher-style choke. This extended choke setup adds durability at the muzzle and is easy to remove or change as needed.
An extended magazine tube runs to near the muzzle, delivering a 7+1 capacity. The stock is a fixed synthetic pistol-grip design with a 14.0 in length of pull, matched to a ribbed synthetic fore-end for a solid grasp. A cross-bolt safety provides familiar control at the trigger guard.
The receiver is steel with a matte black/oxide finish that matches the barrel and furniture. A clamp-mounted metal heat shield is installed over the barrel, and the overall configuration is clean, purposeful, and ready for work.
