Our staff and shipping facility are working efficiently to safely get your orders out.
We are currently running 3-5 business days to process orders. The majority
of our supply chain is intact, but we are having to streamline our product lines a bit to keep up.
Thanks for all of your support and stay safe out there!
The OR3GUN Project aims to address the needs of 3-Gun shooters in
Oregon and beyond, with an eye toward the demands placed on equipment by the elements of our home state.
It should be painfully obvious to most 3-Gunners that when your equipment fails, all of the talent in the world won't get
the job done. Seemingly
random malfunctions with the core group's Mossberg 930 shotguns had plagued many a match over years of competition.
until we had multiple 930s go down simultaneously one night in preparation for a midnight 3-Gun competition that we began
to backtrack through match footage for a common denominator to past malfunctions. Not only did we find that common
denominator, we didn't believe it ourselves until we proved it in 2014.
The result of months of research and development was our first product for the 3-Gun community, the
OR3GUN Marine Spacer Tube
for Mossberg 930/935 series shotguns. Originally designed for the light loads of 3-Gun competition guns in Marine Blue,
we have since introduced the OR3GUN Multi-Use Marine Spacer Tube
in a more bit more visually muted color range.
The Multi-Use version is the same great
design in a 'magnum ready', OEM weighted format suited to buffer those magnum slugs, buckshot and turkey loads in
930/935 models. Hunters and Defenders... this is YOUR version of the MST.
Don't think for a minute that we decided to rest there.
We soon witnessed the evolution of lessened overhang on the tail
of Mossberg’s 930 forearm and the opening of loading ports in the receiver. While techniques and patterns have evolved with
loading techniques, they were limited by the loose tolerances found in the plastic OEM Forearm Retainer.
The rapid acceptance of new dual and quad loading techniques have required that attention finally be paid to the space
between receiver and forearm. The factory configuration leaves just enough gap to regularly catch your hand
on loading attempts.
We developed the OR3GUN Competition Forearm Retainer
(CFR) for incorporation into new or existing Mossberg 930 loading port
The primary purpose is to raise the forearm higher along the receiver, eliminate the play and reduce the gap in front of
the loading port.
This part is available in several model/purpose specific versions.
The popular Quad Ready versions
(Polished or Anodized) are CNC profiled for ramped loading ports and pre-fit to 'generic' receiver and forearm profiles.
We have even developed a specific model for the wood forearm of the Pro Series Sporting.

you need to go for match proven, CNC machined profiles on your supplied polymer forearm with FAST turnaround!
Next in the line-up was the
OR3GUN Enhanced Competition Follower (ECF) for Mossberg 12 Gauge
shotguns. We designed the end to peek out just a bit more than most followers to satisfy your favorite RO and
allow you to quickly feel the difference. We have a version for hunters as well that retains the factory round limiter
and loads the first round smoother on non-modified loading ports.
The lack of hard edges on our follower helps the finish wear longer and our radius approach is a better
way to keep from hanging the crimped end of your shot shell up on any portion of the follower. The rounded edges also
glide smoothly over minor seams and transitions in your magazine tube or extension. Our follower has found favor among
Benelli & Stoeger owners as well. The longer protrusion assists port loads and keeps the round from catching on
the receiver as it is fed into the chamber by the bolt.
Once we had tackled the gas system, it was time to give the recoil system an overhaul. This led us to introduce the
OR3GUN Competition Spring Plunger (CSP) for the 930/935 platform.
Realizing that there is a delicate balance between load weight and reliable cycling, the factory 930 is designed to run
loads as heavy as magnum buckshot and turkey loads. If the competitor is willing to give up some of the heaviest end of
the load spectrum, ground can be gained in the lighter end. Combined with our ASR options, many spring rates are
available to quickly tailor your recoil system to your load range. The full range of 930/935 models are supported.
The unique tail of the CSP captures and guides the spring in addition to producing an effective spring rate reduction
that helps lighter loads run more reliably. The Mossberg 930's recoil system is the subject of our first in a series of
maintenance videos that can be found on our
With the gas and recoil systems under control, we turned our attention to a couple of the finer details of 3-Gun
shooting with a Mossberg. It seemed that nobody had given the 930 platform an enlarged bolt release of its own.
Although there were a number of universals already out there, they required drilling and tapping of small, hardened factory
parts and required complicated disassembly of the gun to install.
Enhanced Bolt Release (EBR) on the other hand, can be installed in
seconds and requires only the included hex key to do so.
The 930/935 specific EBR features a skirted design, which helps prevent any overtravel of the release mechanism. As the
release and shell stop have a bit of play from the factory, our part will ensure a smooth, measured press of the
bolt release under the frantic conditions of competition. Our Tactile version is at home on hunting/security models.
The latest 940 model autoloader from Mossberg incorporates our innovations to address cycling issues. If THAT doesn't
validate our existing line of 930 parts, nothing will. We've got more innovative designs for Mossberg
shotguns scattered throughout our site and many others in progress. Stay tuned!
