OR3GUN manufactures competition-grade aftermarket components for Mossberg 930, 935, and 940 series shotguns. The entire product line was born from years of competitive 3-Gun experience—not corporate guessing about what shooters need.
Standard Mossberg followers blend into ammo colors, making it easy to miss an uncleared gun in a competition dump. The factory bolt release requires fumbling in gloved conditions. The recoil system springs carry burrs that wear plungers and cause light-load reliability issues after high round counts. OR3GUN designed specific solutions for each.
Marine Blue or Red Cinder anodized aluminum — instantly distinguishable from shot shells in your dump box.
Key features: - Radiused edges instead of sharp chamfers—reduces finish wear and prevents crimped shell ends from hanging up - Polished 6061 T6 alloy for reduced friction through magazine tubes and extensions - Oversized drain hole (they actually named it "Drain" after an Oregon town) prevents moisture trapping and corrosion in sealed magazines - Sized for proper transition over minor imperfections in tube extensions without eating shell capacity - Fits both OEM and aftermarket springs with room to spare
| Application | Color | Price | Notes |
|---|---|---|---|
| 3-Gun/Competition | Marine Blue | $24.95 | Bright, easy to show clear |
| Waterfowl/Hunting | Red Cinder | $26.95 | Retains factory round limiter |
The Waterfowl version keeps the factory round limiter for non-extension applications where you need compliance with hunting regulations.
No drilling, no disassembly, no power tools required.
Drop-in replacement that doubles the diameter of the factory bolt release: - Stainless steel set screw secures to factory part without modification - Textured surface designed for gloved use and low-light manipulation - Skirted design prevents accidental shell feed to lifter and stops overtravel - Radiused back won't mar receiver hard coat anodizing - Pitch Black anodized finish, in stock at $24.95
"There is NO DRILLING of any factory parts required. There is NO DISASSEMBLY of your shotgun necessary. In fact, there are NO TAPS, DRILL BITS or POWER TOOLS involved in any part of the EBR-930 installation process."
When Mossberg released the 940 JM Pro, it was a step forward—but OR3GUN found they left the recoil system unchanged from the 930.
940-Specific ASR/CSP (Anti-Spring Rupture / Competition Spring Plunger) Set — $54.95 - Captures the sharp spring burr that eats plungers on factory 930/935/940 systems - 7% reduced spring preload for reliable cycling of bulk pack loads - 2-position quick-change design: light position for birdshot through standard loads, heavy for 3" magnums - Lighter overall weight with self-cleaning characteristics - Machined 6061 T6 alloy, Gold Dust anodizing
The 940 comes with the same problematic recoil system as the 930. OR3GUN tested multiple new 940s from different distributors and found the spring burr on every single one. After round counts build up, shooters report 1200 FPS loads won't cycle reliably with OEM parts.
940-Specific Enhanced Bolt Release — Tactile design with aggressive texture, over-travel stop, factory screw mounting, $24.95
Competition Forearm Retainer — Machined aluminum ramped profile for smooth quad-loading without interference from the OEM polymer retainer cap.

OR3GUN doesn't just make different colors and call it done. Every dimension was engineered for real shooting conditions:
Followers are "one of the more finicky items" in shotgun tuning, especially with radical loading port mods. OR3GUN keeps pricing accessible ($24–27 for followers, $24–55 for bolt releases, $109–160 for combos) so shooters can experiment without breaking the bank.
940 Compatibility Note: Some 940s from late 2022 forward have offset plastic bolt buttons keyed to different shell stop variations. These may not be fully compatible with the OR3GUN 940 button without modification. OR3GUN recommends the 930 EBR for these specific applications.
Based in Oregon, OR3GUN brings decades of competitive shooting experience to every part design. Products ship quickly, with most combos in stock. Installation requires only a hex key (included with EBR-930)—no gunsmithing needed.
