Carlsons Replacement Barrel, Carl 87001 Rem 870 12g Barrel 24" Vr Mod

The Carlson's Remington 870 replacement barrel (Model 87001) is a 24-inch vent rib shotgun barrel chambered in 12 gauge, purpose-built for hunters and shooters looking to expand what their 870 can do. Whether you're walking fields for pheasant, hunting turkey, or just want a dedicated upland setup on your most trusted pump gun, this barrel slots right in without gunsmithing headaches.

Construction starts with certified ordnance-grade 4140 steel — the same material spec you'd expect on a serious working barrel — and the bore is chrome lined for durability and easier cleanup after a hard day in the field. The vent rib runs the length of the barrel to reduce mirage heat shimmer and give you a clean sighting plane, finished in a satin matte blue that handles weather without flash. Up front, a red fluorescent bead catches light fast for quick target acquisition, while a brass center bead helps dial in your eye-to-rib alignment for consistent mounting.

The barrel ships with a Modified choke tube already installed — a versatile middle-ground constriction that performs well on upland birds, waterfowl at moderate ranges, and clay targets. The included choke tube is machined from 17-4 stainless steel and threaded to the standard Rem Choke pattern, so you can swap in any of your existing Rem Choke tubes as the situation changes. The 3-inch chamber handles both 2¾" and 3" shells, covering the full range of standard 12-gauge loads.

Compatibility is straightforward: this barrel is designed specifically for the Remington 870 in 12 gauge. If you've been running the same 870 for years, Model 87001 is a clean, cost-effective way to add a second barrel configuration without buying a second gun. Carlson's has been a go-to name in chokes and barrels for good reason — the quality is there without the premium price tag of a factory Remington spare.

Frequently Asked Questions

What Remington 870 models does this barrel fit?

This Carlson's replacement barrel is designed to fit the Remington 870 in 12 gauge. The listing specifies 12 gauge compatibility only — if you have an 870 in a different gauge, this barrel is not the correct fit.

What choke tube comes installed, and can I use other Rem Choke tubes?

The barrel ships with a Modified choke tube already installed, made from 17-4 stainless steel. It is threaded for the standard Rem Choke system, so any of your existing Rem Choke-pattern tubes will thread right in.

What shell lengths will the 3-inch chamber handle?

The 3-inch chamber is compatible with both standard 2¾-inch and 3-inch 12-gauge shells, giving you flexibility across the full range of common 12-gauge loads.

Is this barrel a good choice for upland bird hunting or turkey hunting?

The 24-inch vent rib configuration and included Modified choke are well suited to upland bird hunting and general field use. The Modified choke also performs reasonably well for turkey at moderate ranges, though hunters pursuing turkey specifically may prefer to swap in a tighter choke from their existing Rem Choke collection.
