Button Rifled Barrels
All of McGowen Precisions
barrels are precision pull button rifled. We start out with
certified 4140 or 416R stainless steel. This steel was specifically
manufactured for the use in rifle barrels.
All steel used by McGowen
is carefully put through a series of tests to ensure the quality
and consistency. Typical rifle barrel steel is between 28
and 32 on the Rockwell "C" scale. All rifle barrels
are stress relieved after the rifling process.
We offer barrels in a variety
of calibers from 20 caliber up to 50 caliber. With each caliber
we offer a variety of different twist options. We are adding
new rifling buttons all the time, so if you don't see the
twist you are looking for, keep checking back as we update
our website. Also if you are looking for a twist that is not
show, give us a call and we'll look into purchasing the tooling.
All of our rifle barrels are
truly "hand-lapped". As stated previously in this
website, this is not a catch phrase for us. There are companies
that state that their barrels are hand-lapped, yet typically
their workers are required to do a certain amount of barrels
per day, leaving their customers with a barrel that may have
been lapped between 20-50 laps. We will put as many lapping
strokes through a barrel as necessary to give you the quaility
that you demand and deserve.
Please note that we do not
offer different grades of barrels. Our QA process is such
that at any time during the process of making your barrel,
if it fails inspection, the barrel is started over. Our goal
is to send out the very best product on the market today.
And if after receiving your barrel you find any discrepancies
or flaws in the barrel, we will address them immediately and
try to correct these as quickly as possible.
For more information on each
type of barrel click the link to the left "Barrels"
and choose the option you are interested in. In Chrome Moly
& Stainless Steel Barrels there is a list of each caliber
and twist that we offer. It will also give you the option
of ordering through PayPal.
Cut Rifled Barrels
We are currently in the
process of completing our cut rifling machine. Cut rifling tooling
has been designed and is currently awaiting the tooling manufacturer
to complete the tooling. We do not currently have an estimated
date in which we will introduce our cut rifled barrels. Keep
watching for updates in the future. This note was updated on
May 9, 2014.
We also offer a variety of
"Pre-Fit" barrels. These barrels are chambered,
threaded and crowned. As with any rifle barrel we strongly
recommend that a qualified gunsmith install the barrel on
your action. Some pre-fit barrels will require that the gunsmith
complete the installation by cutting extractor cuts into the
breech. This is common on Ruger #1 & #3 rifles, Mauser
96 and 98 rifles and Winchester Model 70 CRF actions. The
gunsmith should also check the threads against your receiver.
We hold very tight tolerances here at McGowen and typically
the threads will be at the high end (tight) of the tolerance.
This allows for the barrel to fit tight with your receiver,
which in turn improves accuracy. On barrels for the Remington
700, 7, 721, 722, 600, 660, Mauser 96, 98, Ruger M77, M77
Mk II, Ruger #1 & #3, etc, your gunsmith may be required
to turn back the shoulder to provide proper headspace. Barrels
for rifles such as the Savage or REMAGE barrels have a lock
nut and the headspace is achieved by turning the barrel back
onto a closed bolt with the go and no-go gauges. Once headspace
is achieved the lock nut is then torqued on to lock the barrel
