Tapered octagon-to-round .54 caliber rifled barrel, exclusively from Track®

Our .54 caliber rifled barrel has the same outside dimensions as our most popular 20 gauge octagon-to-round barrel, offered 42" length. Other lengths may be ordered up to 42" at small extra cost.

Track's .54 caliber 42" barrel exactly fits Track's pre-inlet stocks:

• Track's English Fowling Gun stock
• Track's French Tulle Fusil-de-Chasse stock (with 42" barrel)
• Track's French Type ‘C' Fusil stock
• Track's French Type 'D' Fusil stock
• Track's North West Trade Gun stock

Our 20 gauge barrel also fits certain other brands of pre-inlet stocks: Pecatonica River Longrifle Company's North West Trade Gun stock, and matches the profile dimensions of the older Sharon 20 gauge 36" barrel (for the rear 36 inches).

Installation in Track's precision inlet stock is easy. Align the barrel wedding band with the wedding band visible in Track's barrel inletting. Square the area behind the breech and tang, hand cutting straight down, until the barrel seats fully down.

Unlike cheap tapered octagon-to-round barrels turned from surplus shotgun barrel blanks, our barrels are made to our exact pattern, on precision CNC machinery. Our barrels fit our pre-inlet stocks quite well, almost a snap fit, greatly speeding assembly. Choose our octagon-to-round barrel, and one of our pre-inlet stocks, to eliminate the tedious hand work of barrel inletting.

Our .58 caliber rifled barrel has a .540" diameter bore with radius groove rifling, and a slow twist for patched round balls. Outside dimensions match our 20 gauge smoothbore barrel, 1" octagon at the breech, threaded for our 3/4-16 plug, with .550" thread depth. The tapered octagon breech is over 12" long, with the front 4" fading to 16 sides. A double wedding band, at the transition to round, is followed by a single wedding band 3" forward. Muzzle is .815" diameter. In-the-white, the barrel is not marked with our brand or caliber stamp. Any flat may be top, to simplify plug installation. See our #LABOR-BP breech plug installation labor option, which includes do-it-yourself instructions.

Weight is exactly 4.85 pounds, before you install plug, lugs, or sights.

Manufactured exclusively for Track®, our best .58 caliber rifled 42" octagon-to-round barrel is gun drilled, reamed and highly finished inside, CNC turned and milled, to exactly fit our stocks, not highly polished outside to reduce cost, since most gun makers prefer to personally polish each barrel. This barrel is made from modern barrel steel, NOT made from the DOM or hydraulic cylinder tubing found in the 41-1/2" barrels sold elsewhere.
