    Definitely worth it it's a nifty upgrade for 870 to increase magazine size for trap shooting and home defense and it was easy to install just cut the spring to the size you need and your ready to go

    Just as posted, extension, spring and barrel clamp. I was surprised it didn't include the magazine tube follower, but I had an extra, so no big deal. Just make sure you order a magazine followers if you order these extensions. Yes, I'm happy with the product. And, yes. I'd order from this vendor again
