Turnaround for barrel threading is around 2 weeks.
Aquila offers barrel threading services for virtually all situations from
just plain threading to machining special adapters. We single point cut
any thread pitch you require and it will be absolutely square and
concentric to the bore. Some mounts do not have the proper relief cuts,
therefore, we machine tenens on all the barrels we thread for proper
Our thread protectors are all
custom machined for the application to match the current barrel contour
such as slab sided barrel and special diameters for autos. Adapters and
thread protectors for autos are specially machined for tight lock up.
Therefore, there is no need for cheap O ring set ups.
All of our adapters and
thread protectors are made from 416 stainless.
We recently were chosen by
Gemtech to handle a portion of their barrel threading work and are happy
to work with Gemtech’s customer to provide any machining services
Several states have past

tight for your can or mounts. If you require “tight” threads,
please send the mount so that we can assure it will screw on
There are three
established Classes of Thread, designated in the Unified series by
adding “A” for screws and “B” for internal threads to show definite
limits and tolerances.
rarely used, thread is that in which a 1 A screw can be run in
readily for quick and easy assembly. The hole is classified as 1
B. The fit is 1 B thread.
thread consists of a 2A screw in a 2B hole. This 2B thread has
wide application, accommodates plating, finishes, and coating to
a limited extent and, therefore, has fair tolerance allowances.
thread means a 3A Screw in a 3B threaded hole for applications
where tolerance limits are close.
Just in case you
weren’t aware, a rifle barrel must be at least 16” long unless it is
a registered short barreled rifle. And, the 10/22 and AR-15
pistols can have barrels shorter than 16”. If you are in
doubt, please inquire. All NFA rules apply. Keep it legal.
