A BRIEF DESCRIPTION OF DOUGLAS BARRELS

BASIC BARREL

This is a rifled bar of steel, cylindrical in shape, with a rough lathe turned finish. These barrels will vary in diameter but will always finish at least 1.150" O.D. These barrels may be had suitable for the Enfield action - 1.225" O.D. - at extra cost. This barrel is available in three lengths as noted on the price list and barrel shape chart. This blank is intended for those gunsmiths who wish to turn and shape their own barrels.

GRADES OF BARRELS AVAILABLE

Standard grade is a barrel that meet our dimensions specifications but may have a minor amount of curvature. Truly, however, I see barrels in our scrap that are straighter than most factory barrels. A PREMIUM grade barrel is one that has been judged straight in checking. It will be marked with the symbol XX to designate this.

AIR GAUGED QUALITY

In the process of checking our barrels all are checked with air gaging equipment. In so doing we find some that are more uniform than others. Those that measure .0001" or less variation for one end to the other are classed as air gaged. This does not mean that should you order a barrel of a lower quality grade that you might not receive a barrel that would have graded AIR GAGE but it does mean that if you specify AIR GAGE you will get a barrel with the tolerance indicated above.
