Home > Fluting
We flute barrels on CNC machinery with flood coolant and offer a wide variety of fluting patterns. Most of our patterns are highly flexible and we can change lead in lengths, helix rates, and vary cutting depths from breech end to muzzle end, etc. We do unique patterns you won't see in other shops like Gain Twist spiral. Fluting turnaround time is generally 6-7 days after receiving payment.

You can order fluting on barrels purchased from our website by noting in the order comments section the fluting pattern and the finish length [we stop 2" short] and we will add the cost of the fluting to your order then next business day.

If you send us a barrel to flute, please mark Top Dead Center [TDC] 6" in front of shank for 'timed' fluting - Straight, Brux & Diamond.

We’ve had recent issues that has caused us to modify our fluting requirements –

- Barrel blanks must be 27” OAL minimum - we can flute shorter finished lengths on those 27"+ barrels

- Factory barrels are ‘At your own risk

- Chambered barrels shorter than 27” OAL are ‘At your own risk

- Max flute length is 24” - i.e. we can start at 6” and can flute out to 30”. If you have a longer barrel we can start further down the barrel if necessary.

- Barrels already crowned should be re-crowned
