The Vang Comp Systems Remington 870 Magazine Tube Extension, 1 Rd is a compact, screw-on upgrade that boosts the capacity of your 12 gauge Remington 870 without increasing overall shotgun length. Machined from solid steel bar stock with a black matte finish, this extension replaces the factory magazine cap and works together with the included stainless steel follower and extended magazine spring to deliver smooth, reliable feeding shot after shot.

This one-round extension is ideal for shooters who want a simple capacity increase for range use, training, or general-purpose defensive setups while keeping their shotgun trim and easy to handle. Compatible with Remington 870/1100/11-87 models and accepting standard sling loops, it installs quickly with no permanent modifications, reflecting Vang Comp Systems’ focus on practical performance and thoughtful design.
