Cast Iron Housing 1.375 Body For Late Model Pump

The Cast Iron Housing 1.375 Body for Late Model Pump is a precision replacement component designed for shooters and law enforcement personnel who demand reliability in their pump-action shotgun systems. This housing serves as the core structural element in late-model pump mechanisms, engineered to restore or upgrade the cycling reliability of tactical and duty shotguns. Whether you're maintaining departmental inventory or restoring a service weapon, this cast iron body provides the durability needed for high-round-count training and field deployment.

Manufactured from ductile cast iron, the 1.375-inch body diameter is dimensionally matched to late-model pump receivers, ensuring proper engagement with bolt carriers and action springs without modification. Cast iron construction provides superior rigidity compared to aluminum alternatives, reducing tolerance stack-up that can compromise cycling under sustained fire or adverse conditions. The compact 5 x 1.5 x 7-inch profile and 0.9-pound weight integrate seamlessly into existing pump assemblies, maintaining the ergonomic balance critical for tactical transitions and follow-up shots.

Pump-action shotgun operators—from patrol officers to competitive shooters—will benefit from the precision fit and durability this Barnes component delivers. Installation requires basic mechanical knowledge; the housing interfaces directly with the pump's internal linkage system and should be paired with compatible action springs and carriers for optimal function. This replacement part is ideal for armorer-level maintenance, duty weapon refurbishment, or custom shotgun builds where reliability cannot be compromised. Verify compatibility with your specific pump model before ordering to ensure proper fit and operation.
