🧠 Frequently Asked Questions
Q: What’s included in a Nordic Components extension tube kit?
A: Most MXT kits include a modular extension tube, long magazine spring, and follower. You’ll also need a shotgun-specific extension nut (sold separately).
Q: Are Nordic extension tubes easy to install?
A: Yes! Most users can install in minutes using basic tools. You may need to remove dimples in factory magazine tubes on some models (e.g. Remington 870 Express).
Q: What’s the best extension length for 3-Gun?
A: Most 3-Gun shooters use +7 to +9 tubes to match barrel length and maximize shell count while staying within division rules.
Q: Do I need a barrel clamp?
A: We recommend a barrel clamp for any extension longer than +4 rounds to stabilize the magazine and support accessories like slings or lights.
Q: Are these legal for hunting?
A: Some states limit magazine capacity for hunting. Be sure to check local laws — shorter +2 or +3 kits may be acceptable.
