TangoDown, Inc. ARC™
with a clean sheet of paper when TangoDown designed the ARC™ magazine.
Traditional approaches were considered, but tossed out. Any feature that didn’t
push the magazine strength or reliability to new levels was left behind for
someone else to use.
The TangoDown ARC™ MK2 magazine upper body features an advanced blend of N12
polymer. N12 exhibits superior strength &
impact resistance when compared to common nylon 6 used in other commercial
polymer magazines. It takes tough abuse
in stride, with no cracked spines or feed lips…even when dropped loaded on hard
surfaces or seated with excessive force. N12 maintains this tensile strength and impact
edge in temperatures ranging from -30 to +140 F, proven in multiple independent
test lab reports against other polymer and metal magazines.
N12 is also superior to nylon 6 as it’s dimensionally
stable when exposed to moisture, meaning the magazine will not swell over
time. Combined with the 2 piece/straight
wall design, ARC™ magazines always
fall free from the weapon with 100% reliability, guaranteed. Magazines can be fully loaded and store
indefinitely with no feed lip spreading issues. N12 costs up to eight times more than nylon 6, but what would you rather trust your life to?
Because of the tensile strength of N12
polymer, the ARC™ magazine can utilize the USGI pattern bolt catch cut
instead of a ’V’ cut with no spine cracking. The ‘V’ cut helps magazines with lower grade
material survive...somewhat. But that
creates bolt catch issues in some weapon systems. The USGI design allows ARC™ magazines to properly fit AR/M4 rifles & carbines as well
as the SCAR 5.56 rifle, with no magazine modifications necessary to prevent expensive
weapon damage. The smaller upper body
can be created in a more efficient mold cycle, which means more feed lip and
spine strength over one-piece body designs.
TangoDown permanently fuses the upper and lower
magazine bodies together with high-strength aerospace-grade adhesives. The same stuff that holds fighter jets
together. Cleaning becomes a snap, with no disassembly. Any debris that enters the magazine easily
shakes out. Shooting the weapon suppressed? Even caked-on carbon washes out with a quick
soak in hot, soapy water. Rinse and you’re done. Magazine maintenance has never been so fast or
positive last-round lock back anti-tilt follower is slotted to allow any debris
in the magazine to be shaken out. The
follower is molded in high-visibility polymer and is driven by a premium
quality, corrosion-proof 17-7 stainless steel spring that lasts beyond the life
of the magazine body. Over 1300
loading/firing cycles have been recorded on a single magazine (that’s
over 39,000 rounds of ammunition!)
The ARC™ MK2 lower
body has a proven internal constant-radius track for smooth cartridge delivery.
Low friction polymer also aids the
malfunction-free performance. External
ribbing on front and rear body edges enable a positive grip when performing
weapon reloads. Deep waffle style
recesses on the magazine sides not only allow quick, non-slip withdrawal from
magazine pouches but add considerable strength as well.
An integral ramp molded in the lower body automatically changes the follower
attitude when loaded to capacity. This
ensures the first 5 cartridges fired
from the magazine are just as reliably fed as the last 5. This important
feature was engineered and pioneered by TangoDown, but copied by others.
Magazine eliminated the traditional magazine floor plate to create a 5 sided
box. This makes ARC™ one of the
strongest, toughest magazines you can buy. It also means no floor plates to fail
when dropped fully-loaded on concrete, or fighting tangled magazines inside
your pouches during speed reloads.
