Description
Carlson's 24-inch vent rib barrel is a drop-in way to breathe new life into a 12-gauge Remington 870, whether your old barrel is tired, you picked up a bare receiver, or you just want the flexibility of screw-in chokes on a gun that never had them. It is built from certified ordnance-grade 4140 steel with a chrome-lined bore, which stands up to heavy use and makes cleanup a lot less of a chore. The 3-inch chamber handles both 2-3/4 and 3-inch loads, and that 24-inch length splits the difference nicely between a quick-swinging upland setup and the reach you want for waterfowl or turkey.
What the Carlson's 870 Barrel Brings to the Field
The vent rib sits up top to help dissipate heat and give you a clean sight plane down to the red fluorescent fiber-optic front and brass center bead. That setup pulls your eye right where it needs to be, which pays off on fast crossing birds or when you are tracking a bird against a busy background. The satin matte blue finish keeps glare down and looks sharp without drawing attention.
Choke Flexibility on the Carlson's Vent Rib Barrel
This barrel is threaded for the standard Rem Choke system and comes with a Modified Carlson's choke tube already installed. The Modified constriction is a solid all-around starting point for everything from clays to pheasants, and because it is interchangeable, you can swap in a tighter or more open tube depending on the day. Carlson's cuts their field choke tubes from 17-4 stainless steel, so they hold up well and thread in and out smoothly. Longtime 870 owners who ran older fixed-choke guns love finally having that option.
Fitment Notes for the Carlson's 870 Replacement Barrel
This fits 12-gauge Remington 870 shotguns, right-hand models. It will not fit the Remington 870 Tactical versions or any 870 running the full-length six-shot magazine tube, so double-check your gun before ordering. For standard Wingmaster and Express style 870s, folks consistently report a clean, tight fit right out of the box.

Frequently Asked Questions
Will this Carlson's barrel fit my Remington 870?
It fits 12-gauge Remington 870 shotguns, right-hand models, including common Wingmaster and Express style guns. It will not fit the Remington 870 Tactical models or any 870 set up with the full-length six-shot magazine tube. If you are unsure, check your magazine tube length before ordering.
Does the Carlson's 870 barrel use screw-in chokes?
Yes. It is threaded for the standard Rem Choke system and ships with a Modified choke tube already installed. That means you can swap in other Rem Choke compatible tubes to open up or tighten your pattern for different hunting and clay setups.
What kind of shells can I run with the 3-inch chamber?
The 3-inch chamber lets you shoot both 2-3/4 and 3-inch 12-gauge loads. That covers most upland, waterfowl, turkey, and target shooting needs out of one barrel.
Is the bore chrome lined on this Carlson's replacement barrel?
Yes, the bore is chrome lined and the barrel is built from certified ordnance-grade 4140 steel. The chrome lining helps resist wear and makes cleaning noticeably easier compared to a bare steel bore.
