A Carlson's Remington 870 12 gauge 3" barrel with an 18.5" bore and breacher-style choke is built for shooters who need a dedicated short barrel for tactical work, home defense, or specialized hunting applications. This replacement barrel swaps directly onto any Remington 870 platform, giving you a more maneuverable setup without buying a second shotgun. The ramped front sight and matte finish keep things practical and snag-free, while the included Rem Choke tube system lets you adjust your pattern on the fly.
Carlson's constructs this barrel from certified ordnance-grade 4140 steel with a chrome-lined bore—the same metallurgy you'll find in purpose-built fighting shotguns. Chrome lining extends barrel life, resists corrosion, and handles repeated firing without premature wear. The 18.5" length splits the difference between a full-length hunting barrel and a true short-stack tactical tube, making it a solid all-purpose choice if you're running a single 870 across multiple roles.
The ramped front sight is machined integral to the barrel and finished in matte (non-reflective) black, eliminating glint and snag points. The Rem Choke tube that ships with the barrel is manufactured from 17-4 stainless steel, built to handle the pressures of modern shotgun loads. Threading is the standard Remington Choke pattern, so you can swap tubes from your existing choke collection or source aftermarket options to dial in tight patterns for slugs, buckshot, or bird loads.
Installation is straightforward on any Remington 870—no fitting, no gunsmithing. This is a true drop-in barrel replacement. If you're looking to add a shorter, harder-working tube to your 870 without the cost of a second gun, or if you need a dedicated breacher choke for tactical training, this Carlson's barrel delivers the durability and versatility that made the 870 a standard in law enforcement and hunting camps for decades.
| Caliber/Gauge | 12 Gauge |
| Barrel Length | 18.5" |
| Chamber | 3" |
| Material | Certified Ordnance-Grade 4140 Steel |

| Sight | Ramped Front Sight (Matte Finish) |
| Choke System | Remington Choke (Rem Choke) Threading |

Yes, this is a direct-fit replacement barrel for all Remington 870 models. Installation requires no modification or gunsmithing—simply remove your existing barrel and install this one.
The barrel is threaded for the standard Remington Choke system. A breacher choke tube (17-4 stainless steel) is included and pre-installed, and you can swap in any other Rem Choke–compatible tubes to change your shot pattern.
A breacher choke is designed to keep shot pellets together and moving downrange reliably over short distances, making it well-suited for tactical applications, home defense, and close-quarters work. Standard hunting chokes are optimized for different patterns at longer ranges depending on the game and ammunition you're using.
Yes—the 3" chamber handles both 2.75" and 3" loads across buckshot, slug, and birdshot ammunition types. Choke selection will influence your pattern; you can experiment with different Rem Choke tubes to find what works best for your loads and intended use.
