Midweight Hammer Forged Barrel, Carbine, .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.
Midweight profile is .750 under the handguard and .740 in front of the .750 gas journal.
THESE SERVE AS HBAR SERVICE BARRELS. HBAR ENGRAVING AVAILABLE AS AN OPTION
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.
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.
