"Nice packaging, smooth install, took duracoat well, survived initial slug testing, have not yet tested the physical durability in a thrusting use, but added barrel clamp for the customer just in case. Baring any future failures, Id recommend this to other customers and friends."

"Ordered this for my home defense 870. Fits right on. Be advised, you must remove the magazine dimpled if they are present or the follower will not go into the extension. The stand-off teeth don't fully stick past the muzzle, only about half does, but they're sharp! Great accessory for any type of home defense or tactical shotgun. It will unscrew with extended firing if you don't have a magazine clamp. So buy one of those and Loctite the end cap on. Over great product, I keep loving ATI more and more."
