4 stars because plastic follower - Wilson Combat Extension Tube for 12 Gauge Remington M870/1100/11-87

Fit and finish is nice. Easy to install as most 870 parts are (note you'll need to get rid of your mag tube dent). My only complaint is the follower. Its plastic. Its dumpy. Buy a GG&G or Phase 5 follower. I would pay extra $ if this kit included a better follower.
