For larger diameters — Heavy Varmint or 1.250″ straight.

Spiral flutes

More weight reduction than straight — the flute is wider and wraps the barrel for a longer cut. Right or left hand, with any realistic helix you want, and straight or spiral lead-in. Our standard spiral is a 35° twist rate.

Before you send a barrel

These requirements exist because of problems we have run into. Read them before shipping — it saves us both a phone call.

Fluting requirements

  • Barrel blanks must be 27″ overall length minimum That is a fixturing limit. The actual flute length can be shorter — call if you need more information.
  • Maximum flute length is 24″ We can start at 6″ and flute out to 30″. On a longer barrel we can start further down if needed.
  • Factory barrels are fluted at your own risk
  • Chambered barrels shorter than 27″ overall are at your own risk
  • Barrels already crowned should be re-crowned afterward Best to leave muzzle work until after fluting.

Timed patterns need a reference mark. If you are sending a chambered barrel for Straight, Brux or Diamond fluting, mark Top Dead Center (TDC) 6″ in front of the shank.

How to order

Two ways in, depending on whether the barrel is ours or yours.

Fluting a barrel you buy from us

Add the barrel to your order

Pick the blank you want from the shop as normal.

Note the pattern in the order comments

Tell us which pattern you want — and include your finished barrel length. We stop the flutes 2″ short of finished length unless you direct otherwise.

We add the fluting cost the next business day

The charge is added to your order and the clock starts once payment is received.

Sending us a barrel to flute

Check it against the requirements above

Length, crown and factory-barrel risk all matter before it ships.

Mark top dead center if the pattern is timed

Straight, Brux and Diamond need TDC marked 6″ in front of the shank.

Fill out the inbound work form and ship it with the barrel

Download it below, print it, and put it in the box. It tells us whose barrel it is, what pattern you want, and how to reach you.

Call or contact the shop to arrange it

We will confirm pattern, pricing and where to send it.
