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 Spiral Flats, Wave flutes, and Gain Twist spiral. Fluting turn around 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, Wave & Diamond.
We’ve had recent issues that has caused us to modify our fluting requirements

- Barrels must be 27” OAL minimum
-
Factory barrels are ‘At your own risk’
-
Chambered barrels shorter than 27” are ‘At
your own risk’
-
Max flute length is 24”
-
Barrels already crowned should be re-crowned
