Carlson extended magazine tube by Owen Hawks, Verified Owner, February 14, 2020
Well-built and mounts extremely easy. However the spring they send you is no longer than the spring that was already in my shotgun so it does not always cycle properly. Great tube and good price but count on having to buy an aftermarket spring.

Not the best by Sdhunter, Verified Owner, March 28, 2018
The tube tends to work loose and the support that comes with it works its way down the barrel and creates a rub even if its cranked down. The rub was enough to scrape coating of the barrel. The tube does work however and feeds in my gun just fine.
