JonSEAZ, one of the Rem870.com readers shared his experience with Remington 870 Carlsons barrels:
“I recently bought one of these barrels and an array of Carlson screw-in chokes. At this point, I could not be any happier with it. A very nice barrel, inside and out. The one I received fit my 870 perfectly; the exterior finish flawless; the chrome-lined bore nicely done; the threading cleanly cut and the chokes screw in and out nicely; overall, a very nice barrel which now allows me to play with different chokes on a nominally defensive shotgun.
