ROGGIO ARSENAL AR-15/M16<br />
RA-15 STRIPPED<br />
LOWER RECEIVER<br />
Precision-Machined 7075<br />
Aluminum Forging For<br />
Superb Strength<br />
Semi-auto, small-pin lower<br />
receiver offers features usually found only on custom-machined<br />
specialty receivers—for the price of a basic, mil-spec receiver.<br />
Perfect for building a custom AR in the traditional .223/5.56mm<br />
chambering, or a special-purpose rifle in 6.5mm, 6.8mm, 9mm,<br />
or other caliber that fits a standard AR-15 receiver. Forged<br />
from high-grade 7075 T6 aluminum alloy for superb strength.<br />
Precision CNC machined to final dimensions with tolerances<br />
of less than .001", so it’s ready to accept the combination of milspec<br />
parts. Magazine well is wire-EDM machined with a flared<br />
opening, ultra-smooth interior surfaces, and square corners for<br />
snag-free magazine insertion. Serrations cut into the front of the<br />
receiver provide an extra-secure gripping surface when the support<br />
hand is placed on the high magwell. Standard .154" holes for<br />
hammer and trigger pins let you install the aftermarket trigger<br />
of your choice; .250" pivot and takedown pin holes for compatibility<br />
with a broad range of upper receivers. Diamond-cut engraving<br />
produces the crisp, clean, serial number, logo, and markings<br />
without inducing unwanted stress in the metal caused by other<br />
methods. Hardcoat anodized to MIL-A-8625 Type III Class 2<br />
spec to ensure superb surface hardness, before application of a<br />
tough, commercial-grade Teflon ® coating.<br />
SPECS: 7075 T6 aluminum, hardcoat anodized, matte black finish.<br />
Small-pin, .154” (3.9mm) hammer and trigger pin holes. .250”<br />
(6.3mm) pivot/takedown pin holes. FFL required for purchase.<br />

GAS PISTON RETROFIT KIT<br />
For Enhanced<br />
Reliability,<br />
Smoother Cycling,<br />
Cooler Operation<br />
Lets you convert an<br />
AR-15/M4 carbine to a<br />
smooth-running shortstroke<br />
gas piston operating<br />
system for cooler,<br />
cleaner, more reliable operation, positive cycling, easy maintenance,<br />
and the freedom to fire a wider variety of ammunition.<br />
Designed to function in both semi- and full-auto weapons, the<br />
kit contains all the parts to convert the standard gas impingement<br />
system to the rugged, reliable op system employed so successfully<br />
in the Kalashnikov AK series, FAL, HK416, FN SCAR,<br />
and other tactical rifles. Eliminates the risk of broken gas rings,<br />
sagging gas tubes, and the accelerated wear caused by venting<br />
hot gas, debris, and carbon fouling inside the upper receiver. Hot<br />
gases are vented under the kit’s handguard, away from the operator,<br />
so only the energy required to cycle the action is transmitted<br />
to the receiver. Kit includes a high-performance replacement<br />
bolt carrier with extra mass, an integral impact lug, and other<br />
anti-wear features to protect receiver from the impact of the<br />
piston. The lightweight, low-maintenance stainless steel piston<br />
is housed in a tubular structure that replaces the existing gas<br />
tube and pins directly to your rifle’s factory front sight tower—no<br />
need to install a new sight system. Installs in any mil-spec, factory<br />
upper without permanent modifications; any time you want<br />
to return your rifle to its factory gas system, simply swap out the<br />
piston system and replace the original parts. ab<br />
SPECS: Steel, Parkerized, matte black. Handguard – Polymer, black,<br />
stainless steel heat shields. Includes bolt carrier, piston rod, spring,<br />
piston housing, piston housing support, M4-style handguard, and<br />
instructions. Fits semi-auto and full-auto rifles with M4 profile carbine-length<br />
barrels with .875” O.D. behind front sight housing.<br />

DEDICATED 9mm CONVERSION BLOCK - Designed,<br />
manufactured, and field-tested specifically<br />
for law enforcement personnel who require<br />
an AR-15/M16 dedicated to 9mm ammo using<br />
Colt and modified Uzi-type magazines. Integral<br />
“leg” hooks over the top of the lower receiver to<br />
prevent accidental fall-out. Aluminum body features<br />
extra tight mating surfaces to minimize<br />
the collection of carbon and brass buildup; scalloped hold-actuator<br />
allows unburned powder and other debris to pass through<br />
for uninterrupted cycling. Hold actuator is wire EDM-machined<br />
from high grade, 01 tool steel and functions with the standard<br />
5.56mm bolt hold-open, which is strong, reliable and more readily<br />
available than the 9mm version. (Last round hold-open feature<br />
functions with Colt magazines only.) Ejector is of standard, Colt<br />
configuration for easy replacement. Funneled magazine well<br />
ensures smooth entry and limits rotational movement caused<br />
by variances in magazine taper. Spring-loaded roller maintains<br />
constant tension against the lower receiver well to prevent free<br />
play. Steel, feed ramp is heat-treated for extra strength and superior<br />
wear-resistance. Armorer installation recommended.<br />
SPECS: Body – 6061-T6 billet aluminum, Mil-Spec black anodized<br />
finish. Components – Steel, parkerized finish. Fits all Mil-Spec AR-<br />
15/M16 receivers. Armorer installation recommended.<br />

BOLT/CARRIER GROUP<br />
Self-Lubricating<br />
Surface Treatment<br />
Provides Smooth,<br />
Reliable Function<br />
Drop-in bolt and<br />
carrier group has<br />
a self-lubricating<br />
surface that eliminates<br />
the need to apply oil or grease that can attract dirt, dust,<br />
unburned powder, and carbon and lead to cycling failures. Proprietary<br />
EXO treatment produces an exceptionally hard surface<br />
that’s 40% more wear resistant than chrome plating, with an<br />
ultra-low friction coefficient. Surface is actually harder than<br />
the substrate underneath and will not peel, flake, gall, or rub<br />
off. EXO-treated bolt/carrier groups have been tested to function<br />
reliably without additional lubrication up to 50,000 rounds.<br />
Reduced friction also means less heat generated by metal-onmetal<br />
contact, so the gun runs cooler and parts last longer. Easy<br />
to clean, too—fouling brushes right off. Before treatment, parts<br />
are shot peened for surface uniformity and magnetic particle inspected<br />
to make sure there are no hidden flaws. Gas key is hardened<br />
to USGI specs, chrome lined to resist erosion, and comes already<br />
staked to the carrier. Complete Bolt/Carrier Group comes<br />
fully assembled and ready to drop into any mil-spec AR-15 upper<br />
receiver. Includes bolt, bolt carrier, hammer, firing pin, extractor,<br />
cam pin, and gas key. Every kit is test fired for proper function before<br />
leaving the factory. Separately available Carrier comes with<br />
gas key installed and staked. Bolt includes extractor, ejector, and<br />
gas rings installed. Add the firing pin of your choice. ab<br />
SPECS: Heat-hardened carbon steel, EXO-treated surface, silver<br />
finish. Fits mil-spec AR-15 upper receiver. Carrier does not have<br />
provision for auto sear trip.<br />
