Midweight Hammer Forged Barrel, Midlength, .750 Gas Journal w/alignment notch for use with our TABBED gas blocks (non-tabbed gas blocks will still work.)
In-house
pinned gas block is a tabbed,"ultra low profile", pin-only, gas block
with no need for set screws, and has no threaded holes for them. We now
use a heavy duty, double coiled spring pin which can be driven in/out
in either direction, instead of the old taper pin.
Cold Hammer Forged Barrels
Hammer
forging is a process in which a drilled, reamed and honed blank has the
rifling formed into it by placing the barrel blank on a mandrel that
has the rifling ground into its outer surface. The blank and mandrel are
then placed between two opposing power hammers and the blank is beaten
around the mandrel
leaving the rifling pattern in the barrel. This process leaves an
extremely smooth and consistent surface on the inside of the barrel,
that lends itself to excellent accuracy. The forging process also work
hardens the barrel steel causing a very durable and much longer lasting
barrel. Our barrels have a slight taper to the bore during the hammer
forging process to ensure better accuracy. Our hammer forged barrels are
the best choice for shorter range, combat shooting style and high round
counts.
Midweight profile is .750 under the handguard and .740 in front of the .750 gas journal.
Chrome lined chamber and bore
The
hard chrome used to coat the chamber and bore are harder than the
barrel steel itself. This aids in longevity and also reduces fouling and
corrosion often seen in austere field conditions. Chrome also aids in
chambering, extraction, and overall reliability of the weapon. Thus,
giving the operator a more reliable weapon with less maintenance. We
have our chrome lining applied to twice the thickness of standard small
arms barrels.
Barrel steel
The
steel used in our hammer forged barrels was specifically developed as
machine gun barrel steel to help increase the barrel life under
prolonged rigorous firing schedules.
Twist rate
We
use a 1/7 (1 turn in 7 inches) twist rate in all our barrels. This is
the best overall twist rate for this weapons system. The 1/7 twist will
stabilize any of the light weight 5.56 bullets as well as any other
twist. This twist will also stabilize the newer heavier bullets that are
being used allowing the operator to get the best performance out of
this weapon system.
Chamber
We
use a true 5.56 chamber in our barrels allowing the operator the
ability to use the higher pressure military ammunition on the market and
helping to enhance reliability.
Feed ramps
Our barrels are supplied with extended M4 style feed ramps to enhance overall feeding and weapons reliability.
Finish
The
barrel finish we use is a manganese phosphate finish (Mil-Spec
A-A-59267). This finish allows for better absorption of oils to help
prevent corrosion. These barrels are all finished prior to any gas
blocks being mounted to ensure the entire surface is covered to maximum
protection even under the gas block.
HPT/MP inspected
HPT(high
pressure test) is a process where a proof load rated at 70,000 psi, far
exceeding a normal round, is fired trough the barrel then the barrel is
MPI (Magnetic Particle Inspected) to detect any flaws in the barrel
steel from the proof load. These are standard quality assurance tests
performed on all our hammer forged barrels to ensure the highest quality
product.
