White Oak Precision Service Rifle Uppers
Our service rifle uppers are what we believe to the best available.
They are put to the test every weekend by many of the best service
rifle competitors in the nation, and they pass the test. Many
State, Regional, and National titles have been won by competitors
using our service rifle uppers.
While copied by several others, our rear sight modification
is still the gold standard that the others try to live up to. We
have been improving the AR rear sight with the addition of hardened
steel tracking pins for longer than anyone. And while the others
stop there, that was just the beginning for us. Since 1996, we have
been tightening tolerances, adding new features, using better parts,
and improving the sight all around to insure that you have the most
repeatable sights available for service rifle competition.
Our float tube uses heavy walled tubing for strength
and added weight. The end cap is securely welded to the tube, as
is the sling swivel lug. You will not flex or break this tube.
We currently stock Shilen, Pac-Nor, and Krieger barrels
for use on our uppers. These are all top quality, hand lapped barrels
that will give you the accuracy needed to compete at the top levels
of competition. We have several choices of chambers to suit your
Standard on a White Oak Precision Service Rifle
Oak Precision rear sight eliminates unwanted movement on all
axes by combination of quality parts
and meticulous assembly. Two hardened steel tracking pins are
fitted down through the sight base and into the receiver, preventing
rotational play of the rear sight. The tracking pins also allow
the elimination of the detent ball and spring on the left side
of the base, greatly improving repeatability. The elevation
thread fit to the receiver is held to close tolerances; this,
along with a second elevation wheel ball detent, will prevent
lateral movement of the rear sight base. The sight base screw
and the windage screw are precision machined to our specifications.
The rear sight leaf is threaded to allow for interchangable
aperture inserts. A sight hood is also available. Windage
and elevation are available in 1/4 MOA and 1/2 MOA adjustments.
| Barrels on all White Oak Precision
service rifle uppers are profiled, threaded, and chambered in-house.
This allows us to control the quality of the work and allows
us to offer you choices in barrel manufacturer, twist rate,
and chamber specs.
adjustable front sight base is standard on the White Oak Precision
service rifle upper. The front sight base is forged and machined
to our specifications. Opposing
set screws are installed in the front of the base to allow for
windage adjustment. A single set screw comes up through the
bottom of the rear of the base to lock it in place and form
a tight seal at the gas port. A 0.052" front sight post
is standard, but we can make other sizes upon request. The top
and sides of the post are tapered to provide a sharp sight picture.
A set screw is installed under the sight post to lock it into
place. We adjust the front sight base for windage to center
the rear sight during test firing on all of our service rifle
Oak Precision service rifle uppers are availble in pre-ban and
post-ban configurations. Pre-ban rifles will have a bayonet
lug on the front sight base and an A1 or A2 style flash hider.
Post-ban will have an 11 degree target crown.
The White Oak Precision service rifle float
tube is precision machined on CNC equipment and is the best
and strongest available.
sling swivel lug is welded, not soldered, and the end cap
is welded all the way around for added strength. The bottom
of the sling swivel lug is machined to allow access to the
set screw in the bottom of the front sight housing. One inch
of thread engagement between the barrel nut and tube give
good alignment as well as strength. Precision CNC machining
ensures that the threads are straight and have a proper fit.
This ensures that your barrel is in the center of the tube,
not off to one side. The top of the tube is machined to allow
clearance for the gas tube. Heavy walled tubing adds weight
to the rifle. The barrel nut is machined to allow barrels
up to 1.050" diameter to be installed without modifications
to the barrel or barrel nut.
