The PB6000 was developed in collaboration with Jacob Grey Firearms, a premier manufacturer of 1911/2011 pistols. Known as the Jacob Grey Recoil Reaper, the PB6000 is an aftermarket upgrade designed to replace 4.25”–5” guide rods in a wide range of 1911/2011 platforms.

The KynSHOT PB6003 Hydraulic Guide Rod is engineered as a direct drop-in replacement for standard guide rod assemblies used in Glock 19 Gen 1-3 slides and similar platforms, requiring no changes to your firearm’s existing configuration.

The KynSHOT PB6004 Hydraulic Guide Rod is engineered as a direct drop-in replacement for standard guide rod assemblies used in Glock 17 Gen 5 slides and similar platforms, requiring no changes to your firearm’s existing configuration.

The KynSHOT PB6005 Hydraulic Guide Rod is engineered as a direct drop-in replacement for standard guide rod assemblies used in the Glock 43x and similar platforms, requiring no changes to your firearm’s existing configuration. Its advanced design features a specialized damping system that ensures proper slide cycling while effectively controlling both movement and speed.

The KynSHOT PB6006 Hydraulic Guide Rod is engineered as a direct drop-in replacement for standard guide rod assemblies used in Sig Sauer P365 XL and similar platforms, requiring no changes to your firearm’s existing configuration. Its advanced design features a specialized damping system that ensures proper slide cycling while effectively controlling both movement and speed.

The KynSHOT PB6007 Hydraulic Guide Rod is engineered as a direct drop-in replacement for factory guide rod assemblies in Glock 19 Gen 4 and Gen 5 pistols, requiring no changes to your firearm’s existing configuration.

Designed and manufactured for P7Pro, the PB6002 is designed to be used with any P7K3.

The KynSHOT RB5100 Adjustable Damped Recoil Buffer for shotguns and tactical shotguns

The KynSHOT RB5103 Non-Adjustable Recoil Buffer for shotguns and tactical shotguns

The KynSHOT RB5022 VR80™ Shotgun Recoil Buffer features dual stage damping and the latest advances in recoil management.

The KynSHOT RB5000 is a hydraulic recoil buffer engineered for AR-15 platforms with a Mil-Spec carbine buffer tube (7” internal depth).

The KynSHOT RB5000HP is a hydraulic recoil buffer engineered for over-gassed AR-15 platforms and 9mm radial delayed blowback systems.

The KynSHOT RB5000L is a hydraulic recoil buffer specifically engineered for soft cycling or under-gassed AR-15 platforms.

The KynSHOT RB5001 is a hydraulic recoil buffer engineered for AR-15 platforms equipped with Mil-Spec rifle-length buffer tubes, including A1 and A2 fixed stocks (9.5” internal depth).

The KynSHOT RB5004 is a hydraulic recoil buffer engineered for AR-10 platforms using Mil-Spec carbine buffer tubes with a 7” internal depth.

he KynSHOT RB5005 is a hydraulic recoil buffer engineered for AR-10 platforms utilizing AR-10-length or A5 buffer tubes with a 7.75” internal depth.

The KynSHOT RB5006 is a hydraulic recoil buffer engineered for AR-10 platforms equipped with Mil-Spec rifle-length A1 or A2 fixed stock buffer tubes (9.5” internal depth).

The RB5007 performs reliably in builds with barrel lengths ranging from 3.5” to 7.5” when unsuppressed and works effectively with all common 9mm ammunition. Its carefully balanced weight and length ensure smooth operation, reduced recoil impulse, and proper cycling—stopping just behind the bolt catch. The buffer’s patented hydraulic technology absorbs the rearward energy of the bolt carrier, helping to eliminate bolt bounce during chambering.

The RB5015HD performs best in PCC builds with barrel lengths of 8 inches or longer, as well as in all suppressed PCC setups. It functions reliably across all 9mm ammunition types. Its weight and dimensions are carefully tuned for PCC platforms to ensure smooth cycling, reduced recoil, and proper bolt travel—stopping just behind the bolt catch. The patented hydraulic system absorbs the rearward energy of the bolt carrier, helping to eliminate bolt bounce during chambering.

The KynSHOT RB5020SS Recoil Buffer is a hydraulic buffer system built specifically for competition shooters looking to improve sight recovery and achieve faster follow-up shots with pistol caliber carbines (PCCs).

The KynSHOT RB5030 is a hydraulic recoil buffer engineered specifically for the MR762. Its added weight and refined hydraulic design deliver smoother cycling and improved performance compared to other MR762 buffer options. It is fully compatible with the factory MR762 spring and installs easily as a drop-in replacement for the standard buffer system.

he KynSHOT Spacer Weight, developed in partnership with Blitzkrieg Components, is designed for use with both PCC and other KynSHOT AR hydraulic recoil buffers to increase mass at the front of the buffer system. It adds 0.75 inches of length and 2.5 ounces of weight, fitting closely within the buffer tube to help prevent buffer tilt during operation.
