We can flute any of our barrels. We have three fluting styles.
Standard Fluting - We cut 7 straight flutes around the barrel. Fluting is the full length of the barrel, both under the handguard and forward of the gas block.
Narrow Fluting - We cut 10 or 12 straight flutes around the circumference barrel. Fluting is the full length of the barrel, both under the handguard and forward of the gas block. Narrow fluting reduces the barrel weight more than any other fluting styles.
SDM Fluting is 12 straight flutes around the barrel behind the gas block in the style of the Squad Designated Marksman barrel. This reduces weight and increases cooling capacity in the largest part of the barrel. There is no fluting visible forward of the gas block.
If you wish have your barrel fluted please select the appropriate fluting style below and add it to the cart with your barrel or upper.
