Rebel RBR-15 S MOD 3 

The clear answer to the perfect AR-15 platform is here, not redesigned, not new to the market, plain and simply brought to you with new value and respect. We at Rebel Arms, Primary Weapon Systems and Bootleg Inc. have worked hard to bring you the finest di rifle system in the world, renamed, rethought and redefined. after many months of development Rebel Arms Corp in collaboration with PWS® introduces the Rebel  RBR-15 S MOD 3 and variants. This rifle is fully ambidextrous and has multiple different patented technologies. Rebel Arms is very proud to be the exclusive source for this rifle, and for the first time are offering this ground breaking weapon in multiple configurations and color options. 



Our 14.5" 4150 CMV Nitride barrel is chambered in 5.56x45mm NATO. The 1x7 Twist Rifling is capable of stabilizing light to heavy weight projectiles of up to around 77 grains. Each Rebel Arms Barrel is capable of 1 MOA accuracy using match grade ammunition. 


SilencerCo ASR Muzzle Brake 

 The SilencerCo ASR 3-port muzzle brake is compatible with the Specwar, Saker, Omega, Hybrid, and Harvester Big Bore ASR mounting system. They offer one hand on, one hand off attachment/detachment. The 3-port design effectively reduces felt recoil and muzzle climb. (Ban state rifles will come with the SilencerCo Saker Trifecta Muzzle Brake. The ASR Blast Sheild will not work with the Saker Trifecta Muzzle Brake.) 


Upper Receiver 

Our lightweight Complete Upper Receiver offers less weight than a mil-spec upper receiver and we’ve done away with the forward assist to reduce snag risk. 

  • Machined from forged 7075 aluminum to keep it light 

  • Mil spec hard anodizing for durability 

  • 1.7 oz. lighter than a mil spec upper receiver with hardware installed 

  • Captured dust cover door pin eliminating the need for the E clip 

Lower Receiver 

The Rebel MOD 3 lower receivers are forged, allowing for a much stronger and lighter product. A common known fact that has been lost through the marketing efforts of many AR 15 manufacturers is that a forging can produce a piece that is much stronger than a billet part. As the metal is shaped during the forging process, its internal grain aligns to follow the general shape of the part. As a result, the grain is continuous throughout the part, giving rise to a part that is stronger, yet lighter, than a billet receiver. 

Weight – 7.5 oz. 

7075 Al Forged 

Flared Magwell 

Fire Control Group

The Rebel RBR-15 S MOD 3 comes with a premium mil-spec fire control group.  The trigger pull is measured at 5-7 lbs. with standard length reset. 



The enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction area and the slight increase in carrier mass extends dwell time and ensures proper gas pressures for reliable extraction. 

Forward Controls Enhanced Magazine Release-Competition 
The Enhanced Magazine Release-Competition features a slightly curved button surface to fit the natural curvature of your finger. The form fitting curve, along with horizontal serrations, create a self-centering surface that inhibits the finger's vertical movements. The EMR-C has an uninterrupted surface and serrations, its taller profile makes it easier to press and is only 0.04 taller than the factory magazine release button. 

 Forward Controls Augmented Bolt Catch/Release 

ABC/R (Augmented Bolt Catch/Release) with its angled and larger top paddle and lower paddle with increased surface area, is purpose designed for use with AR15/M16 receivers equipped with ambidextrous magazine releases. Specifically, it is designed to address the difficulty with accessing the factory bolt catch's lower paddle with an ambidextrous magazine catch, such as Norgon's Ambi-Catch, on the receiver. Many of the ambidextrous mag release's lower paddle is on the same vertical plane as the factory bolt catch lower paddle, making identification difficult by feel, especially with a gloved hand.  

Ambidextrous Safety Selector 


The Talon™ ambidextrous safety selector is a modular design that can be installed as a standard 90° or as a 45° short throw by simply rotating the shaft 180° inside the lower receiver. Selector levers install using a precision machined dovetail interface with spring-loaded retention stud to lock the lever in place – no screws to come loose or break. 


Charging Handle 

The Raptor Pistol  comes standard with a RAPTOR-LT AMBIDEXTROUS CHARGING HANDLE 

Raptor-LT. Utilizing the same patented ambidextrous functionality as its predecessor, the Raptor-LT handles are machined from 7075 aluminum, MILSPEC Type III hard anodized, then over-molded with high-strength, fiberglass reinforced polymer for the ultimate combination of strength, weight, and durability.



  • Extruded 6061 aluminum to keep weight down 

  • Mil-spec hard anodizing for durability 

  • Full length mil-spec Picatinny top rail 

  • PicMod rails allow mounting KeyMod and Picatinny accessories  

Our specially designed handguard rail has a Picatinny rail on top and our specially designed PicMod handguard rails on the other three sides. This technology combines both Picatinny and KeyMod rail systems so you can attach nearly all KeyMod and Picatinny accessories with ease. Get the best of both worlds with Bootleg, Inc.’s specially designed handguard rail system! 


13″ Handguard 

  • 8.6 oz. without mounting hardware 

  • 1.675” wide, 2.05” wide, 13.4” long 

  • Designed to work with any barrel 14.5” or longer 


MOD 2 Enhanced Buffer Tube With Ratchet Lock Castle Nut & End Plate 

Impact extruded from 7075, the PWS Enhanced Buffer Tube is optimized for strength and rigidity while creating a solid platform for the new lightened design. Anodized in Mil spec type 3 to exceed standards in hardness and corrosion protection. The patent pending Ratchet-Lock Design eliminates the need for staking the castle nut and gives a rock solid lock up while being able to remove it easily if needed in the future. The anti-tilt lip enhances function and reliability, giving longer life to piston driven weapons by allowing the carrier to start in the buffer tube rather than transitioning into the tube on extraction. 


 Magpul MOE Grip: 

The MOE Grip (Magpul Original Equipment) is a drop-in upgrade for the standard AR15/M4 pistol grip. The ergonomic, hand filling design combines anti-slip texturing with storage core capability. With a similar shape to a 'medium' sized MIAD, the one-piece reinforced polymer construction provides simplicity and a reduced cost while still maintaining the durability needed to withstand operational environments. The MOE Grip accepts optional Storage Cores for gear stowage and includes a basic grip cap. All mounting hardware included. 

Magpul MOE SL-K Carbine Stock: 

A drop-in replacement buttstock for AR15/M4 mil-spec carbine buffer tubes, the SL-K is designed for compact PDW style weapons or users desiring a small and light stock. 



Magpul PMAG GEN M3 



Each RBR-15 S MOD 3 comes with a Patriot hard case.
