Why Buy Barrel Theading From IslandFab?

  • No matter what the purpose of your threading job, whether its for a muzzle device or suppressor, we ONLY thread concentric to the bore. Our process allows us a tolerance <.0002". We use the same setup procedure for barrel threading and crowning that we use for custom chambering.
  • We have multple lathes
  • You can send us your barrel only, barreled action, or full firearm if you wish (just stripped of accessories)
  • We thread based on suppressor manufacturer recommendations
  • We can add tapered shoulders for slim sportster barrels
  • We have a full-time gunsmith on staff

 

Standard Caliber Based Threads (Excluding Metric or Left Hand)

Caliber Thread Default Min. Muzzle Diameter Thread Length
Rimfire 1/2-28 .560" .400"
.20 - .24 1/2-28 .560" .600"
.243 - .358 5/8-24 .685" .600"
.375 - .458 3/4-24 .810" .600"

 

If the barrel diameter is smaller than the minimum muzzle diameter we will thread to a secondary thread size and a shoulder would need to be added to keep the bore wall thickness at a recommended value.

Example: 300 Win Mag Sportster Barrel muzzle diameter is .610. We would thread this to 9/16-24, add a shoulder then turn down an adapter to match giving you an end result of a 5/8-24 thread with a large enough shoulder and ample barrel thickness at the muzzle.
