TM M870 Replacement Pump Arms
Durable Replacement Arms for Your TM M870 Shotgun
Upgrade your TM M870 Pump Shotgun with these high-quality replacement pump arms. Designed for compatibility with both the tactical and breacher-type shotguns, these arms provide a reliable and durable solution to keep your shotgun in top condition.
Key Features:
- Includes right and left arms for complete replacement
- CNC machined aluminum for strength and durability
- Anodized black finish for a sleek, tactical look
Expert installation is recommended, and modification may be required. These are only a single front screw used in older model TM Breacher Pumps. They will still work with newer versions but will have one screw instead of two on the pump.
