  The Maxim Defense Roller Delayed Buffer (RDB) System transforms your 9mm AR-pattern firearm into a roller-delayed blowback system, reducing felt recoil and boosting reliability.By allowing gas pressure to stabilize before extraction, it ensures smoother operation while virtually eliminating friction common in standard buffer systems. NOTE: The RDB System is designed specifically for 9mm AR platforms and is not compatible with other calibers. Compatibility Compatible with AR-15 9mm Blowback Systems ONLY Compatible with CARBINE LENGTH Buffer Tubes ONLY NOT compatible with SCHMEISSER models NOT compatible with CMMG Radial Delayed Blowback models Compatible accessories see under this article, accessories  Package Contents MAXIM DEFENSE RDS System - Carbine Length, Buffer Weight: 8.3 oz. KEY FEATURES: Reduces felt recoil increases reliability Minimizes friction for enhanced performance IMPORTANT INSTALLATION NOTE FOR RDB SYSTEM To install the Roller Delayed Blowback (RDB) System, your 9mm bolt assembly must have an open channel to allow the guide rod to function properly during firing. For most 9mm bolts, meaning you will need to remove the pinned-in central mass. The central mass must be removable, but the bolt carrier group (BCG) should retain its full length without it, to ensure proper function with the RDB system. MADE IN THE USA

   JP Silent Captured Spring Buffer Retainer Pin and Spring While you can use a standard buffer retainer pin and spring with your Silent Captured Spring, installation and removal is difficult to say the least. Until now, that's left the only option of storing the SCS loose. Fortunately, we have a solution. This new buffer retainer pin design allows for easy installation and removal of the Silent Captured Spring while ensuring unerring retention. Your SCS will never drop unexpectedly out of your lower again. Plus, this design works equally well with a standard AR buffer and spring. It's a little thing, but what a difference it makes. Compatibility: Like a standard buffer retainer pin, this design is not compatible with Variable Mass Operating System (VMOS™) carriers. This buffer retainer pin is designed to work only with conventional buffer tubes and not those with a slotted lip feature designed to extend around the buffer retainer pin. The slotted feature may prevent this buffer retainer pin from fully presenting and will not retain the SCS. When running a Silent Captured Spring in this type of buffer tube, we recommend against use of buffer retainer pin. This buffer retainer is designed for use with the JP Silent Captured Spring and will not retain a standard buffer assembly as well as a Mil-spec buffer retainer.  MADE IN THE USA

  Standard Power - Rifle Length - Buffer Spring + XP 5-Coil Bolt Extractor Spring The Green spring is for use in A1 / A2 fixed stock rifle length buffer tubes with rifle length buffers. It is also extremely popular in intermediate depth (7.75 “ deep) VLTOR A5 buffer tubes with 4” A5 buffers. The spring design loads of the Green spring are those of a BRAND NEW mil-spec buffer spring. While the Green spring is primarily for use with lesser calibers such as .223, 5.56. 6.8 SPC, 6.5 Grendel, 7.62 X 39, etc. in A2 rifle length tubes, it may sometimes be appropriate for use in long BBL (20”+) rifle length gas BBL’s in heavier calibers such as .308 and 6.5 CM, .260 Rem, etc.. (May not be effective for unsuppressed 7.62 X 51) In the latter scenario, an H2 or H3 carbine buffer has been used successfully in rifle length tubes with the Green spring.

  Reduced Power - Carbine Length - Buffer Spring + XP 5-Coil Bolt Extractor Spring We collaborated with two prominent commercial ammunition manufacturers and two prominent gunsmiths to arrive at the design for the Yellow spring. It’s approximately 20% lighter than the White spring, and was the consensus choice out of 4 different evaluation samples provided to all parties. They all added in their final evaluations that if a particular gun needed a lighter spring, that the gas port should be enlarged for overall reliability. The Yellow spring is also appropriate for with low power SRTA training or SIMS Rounds for training operations. Useful for undergassed rifles, such as some mid-length gas rifles or rifle lenght “Dissipator” 20'' inch builds which is apparent with rifles that short stroke or have weak ejection patterns. Color Coded YELLOW.

  Reduced Power - Carbine Length - Buffer Spring + 4-COIL Bolt Extractor Spring We collaborated with two prominent commercial ammunition manufacturers and two prominent gunsmiths to arrive at the design for the Yellow spring. It’s approximately 20% lighter than the White spring, and was the consensus choice out of 4 different evaluation samples provided to all parties. They all added in their final evaluations that if a particular gun needed a lighter spring, that the gas port should be enlarged for overall reliability. The Yellow spring is also appropriate for with low power SRTA training or SIMS Rounds for training operations. Useful for undergassed rifles, such as some mid-length gas rifles or rifle lenght “Dissipator” 20'' inch builds which is apparent with rifles that short stroke or have weak ejection patterns. Color Coded YELLOW.
