Remington 870 Replacement Barrel Problem
I recently bought a 21″ vent rib barrel with choke in hopes to do some turkey hunting this coming season.

With this 21″ barrel the guide ring that goes around the tube is further down than the stock barrel and the cap doesn’t hold the barrel in place.

Remington 870 Replacement Barrel Problem
My question is, is there anyway I can use this barrel with this gun? Would a barrel clamp do the trick in keeping the barrel in place or can I just not use this barrel. I know this gun is meant for home defense but I was hoping to be able to make it an all around use kind of gun.
Here’s a pic of the two barrels so you can see how the guide rings are in different places.
