The Kynshot RB5007 recoil buffer for 9mm AR-15s brings hydraulic shock absorption to your platform carbine. Like the dampening system in a vehicle's suspension, this stainless steel buffer uses a hydraulically dampened piston to absorb bolt carrier impact and smooth out recoil impulse. The result is less felt recoil, faster target reacquisition, and more controlled follow-up shots—whether you're running a suppressed 5-inch pistol or an unsuppressed 16-inch carbine.
Built from stainless steel, the RB5007 is engineered to cycle smoothly across any 9mm AR-15 platform and ammo type. The buffer's weight and length are optimized to arrest the bolt just behind the bolt catch, eliminating the need for a spacer. You get faster sight recovery, reduced spring noise, and less mechanical wear—the kind of refinement that pays dividends over thousands of rounds.
Installation is straightforward: this drop-in recoil buffer integrates into your existing AR-15 platform with no special tools or modifications. It's the kind of upgrade that works silently in the background, making your 9mm carbine noticeably smoother to shoot and easier on both you and your gun.

Frequently Asked Questions
Will the Kynshot RB5007 work with my suppressed 9mm AR-15?
Yes. The RB5007 is compatible with 9mm AR-15s firing both suppressed and unsuppressed, and works across any ammo type.
Do I need a spacer with this buffer?
No. The RB5007's weight and length are optimized to stop the bolt just behind the bolt catch, so no spacer is required.
What's the advantage of hydraulic dampening over a standard buffer?
The hydraulic piston absorbs shock from bolt carrier impact, reducing felt recoil, speeding sight recovery, and decreasing wear on internal components. You also get smoother cycling and less spring noise.
What 9mm AR-15 barrel lengths does this buffer support?
The RB5007 is compatible with any 9mm AR-15 from 5-inch pistol uppers to 16-inch carbines.
