American Rifleman - September 2017 - 90

DOPE BAG

Standard Mfg. Co. DP-12
A

sea change in defensive shotgun
design has occurred during the
past decade. Beyond upgrading
existing platforms, the trend has been
to find unconventional ways to maximize firepower from a small platform.
One such firearm that embodies this
movement is the subject of this review,
the Standard Mfg. Co. DP-12.
The DP-12 is a bullpup-style, pumpaction, side-by-side, 12-ga. shotgun
with dual magazine tubes. Essentially,
it combines the handiness and rapid
firing of a Western-style "coach gun"
with the sure functioning and firepower of a pump-action shotgun. Since
the action is located behind the trigger
group and integral with the buttstock,
the gun measures only 29½" long
while featuring twin 187⁄8" barrels.
The DP-12's barrels are machined
from round bar stock, and they flare
considerably approaching the aluminum muzzle support. Chambered
for 12-ga., 3" shells, the barrels are
threaded to accept Tru-Choke-pattern
choke tubes. A "Max Spreader" choke
tube is provided for each barrel. Shells
measuring less than 2¾" in length
are safe to use in the DP-12; however,
the company recommends testing
for functionality before pressing
these diminutive loads into service.
Tubular magazines that facilitate

90

in-line feeding are located beneath
the barrels. Each magazine holds
seven 2¾", 12-ga. shells, bringing the
total capacity to 16 rounds when two
rounds are chambered. Shell indicator
windows in the magazines permit visual
confirmation of the rounds remaining. The oversize loading/ejection port
is located behind the pistol grip and
forward of the butt.
The DP-12's receiver is machined
from aircraft-grade 7075 aluminum.
Company literature reports that it has
a thermal coating, too-given the
DP-12's potential high rate of fire,
that's a prudent decision. Since the
bolts lock up with steel barrel extensions, and thus the receiver is subject
to minimal stress, the use of aluminum there is justified. At the front
of the receiver is a black, two-piece,
polymer shroud to protect the shooter
from heat. Extending from the top
of the receiver to the shroud is an
aluminum rail that provides rear support for a 13¾" (34-slot) section of
Picatinny rail. The latter, which is also
crafted from aluminum, is secured at
the front to the muzzle support. Open
sights aren't provided.
Beneath the receiver-and extending from the pump pad shroud forward
more than half the gun's length-is
the grip assembly, which, like the
SEPTEMBER 2017

AMERICAN RIFLEMAN

shroud, is made from two halves. In
addition to the ejection/loading port,
the grip assembly contains the fire
controls. The bilateral, two-position
safety mimics that on AR-pattern rifles.
Creep of the single-stage trigger was
nonexistent, and reset was surprisingly
short, too; however, the pull weight was
exceptionally heavy, as is often the case
with bullpup designs. Whereas the trigger broke on the right barrel at 11 lbs.,
10 ozs., the left barrel exceeded the
12-lb. limit of the trigger-pull gauge.
The action release lever is located on
the front of the trigger guard and is
actuated by pulling down.
The thinness of the DP-12's pistol
grip and flaring nearing its bottom
enable a solid purchase. Further
enhancing grip are raised sections on
each side of the pistol grip and urethane strips adjoined to the backstrap.
The gun's center of gravity is located
directly above the pistol grip. At the
bottom of the two-piece, polymer
fore-end is a seven-slot, 33⁄8" section
of Picatinny rail to which a composite
grip handle is attached. Thanks to the
six slots on the fore-end, there are 18
total slots on the gun to add Magpul
Original Equipment (MOE) rails.
Beneath the thin, rubber recoil
pad are dual recoil springs. Given
the gun's 9-lb., 12-oz. empty weight,
