Carlson’s 870 12 Gauge 18.5″ Breacher Barrel

The Carlson’s Choke Tubes 870 Breacher Barrel (Carlson’s part number 87006) is an 18.5-inch replacement barrel built for the Remington 870 in 12 gauge, fitted with a ramped front sight and Carlson’s tactical Breacher choke tube. It is machined from certified ordnance-grade 4140 steel with a chrome-lined bore for corrosion resistance and long service life, then finished in blued matte for a low-glare, duty-ready look. The shorter 18.5-inch length and fixed Breacher choke make this barrel a natural fit for home defense and tactical 870 builds rather than field or clays use. It is built specifically for the standard Remington 870 and does not fit the Remington Tactical 870 variant.
