The Scattergun Technologies parkerized magazine tube extension with right-hand side sling mount transforms your Remington 870, 1100, or 11-87 12-gauge into a more versatile defensive or tactical shotgun. Built tough enough to earn trust with the U.S. Secret Service and Border Patrol, this extension boosts your magazine capacity to five rounds while adding a dedicated sling mount on the left side—purpose-built for right-handed shooters who need faster target transitions and better weapon control in high-stress situations.
This isn't just a tube extension; it's a complete upgrade package designed by shooters who understand shotgun fundamentals. The included extra-power magazine spring ensures reliable feeding under real-world conditions, while the high-visibility follower lets you instantly confirm magazine status without breaking your sight picture. The parkerized finish delivers that time-tested durability—the same rust-resistant, battle-hardened coating that's protected fighting shotguns for generations.
Whether you're running a dedicated home-defense rig, training for 3-gun competition, or maintaining a patrol shotgun, the added capacity and integrated sling mount eliminate the need for separate aftermarket accessories. The wave washer inclusion shows the attention to detail that separates purpose-built gear from generic mall-ninja add-ons. If you run a classic Remington 870 platform and want measurable improvements in speed and capacity without sacrificing reliability, this is the extension that does the job.
