ROTO 4M HAMMER FORGED
Built to precise tolerance by a special hammer forging process, these barrels are the best you can buy! The hammer forging forms the barrel around a precision mandrel and holds the tolerance to .0001". This is much better than the typical broached barrels found elsewhere Note: 5" & 6" .45 barrels are L.H. twist – all others are R.H. twisted
COMPARE THE ROTO-4M BARREL FOR ROUNDNESS AGAINST A STANDARD BROACHED BARREL FROM A WELL KNOWN MANUFACTURER. ALL ROTO-4M BARRELS ARE MADE IN THE USA.
Brand new extra length barrels for all Colt/1911/Government Model type automatic pistols. These barrels are made by the Special Roto-4M Hammer forge process which produces the most precise and consistent barrels for the best accuracy. Minor hand fitting may be necessary for some guns.
Note: 9mm & .38’s will not fit the .45 slide
