9mm Hydraulic Buffer & Spring Package - Standard Damped
For AR15 PCC Carbines with 5" - 8" Barrels
Package Includes RB5007 Standard Damped 9mm Buffer & Sprinco .223 Carbine Extra Power Buffer Spring (Red)
If you have a typical AR15 PCC 9mm with a barrel length of 5" to 8", this is the standard package to use. It will drop into a standard AR15 collapsible stock or AR pistol arm brace set up. The RB5007 buffer has a standard level of hydraulic resistance and a standard piston return spring for best performance in shorter barreled PCC guns. The .223 extra power carbine spring has proven to be best for these barrel lengths over the majority of PCC guns.
* For barrels shorter than 5" a lighter buffer spring is often needed and takes some trial and error to find the best for your gun and loads. Lighter springs are available separately.

What is the best buffer and spring set up for my 9mm AR PCC with a 5” barrel with a Shroud to make it 16” for competition as a short-stroke system?
Use one of two combinations:
The Springs are stronger because this is a short stroke set up and the bolt needs to slow down faster.
What is the best buffer and spring set up for my 9mm AR PCC with a 5” barrel with a Shroud to make it 16” for competition as a full-stroke system?
Use an RB5007 Standard Damped 9mm buffer and a Sprinco Red or other extra power .223 carbine buffer spring. Sometimes trial and error is necessary with buffer spring selection with various loads to find the sweet spot of performance and feel.
What is the best buffer and spring set up for my 9mm AR PCC with a 16” barrel for competition as a full-stroke system?
Use the RB5015HD High Damped 9mm buffer and .308 carbine buffer spring in a standard carbine buffer tube or use the same buffer and spring plus the PCC buffer weight in an A5 buffer tube for a slightly smoother/softer system.
What is the best buffer and spring set up for my 9mm AR PCC with a 16” barrel (PCC is Pistol Caliber Carbine)?
Use an RB5015HD (High Damped) 9mm buffer and a .308 carbine buffer spring such as a Sprinco Orange or JP .308 carbine spring.
What is the best buffer and spring set up for my 9mm AR PCC with an 8-11” barrel?
What is the best buffer and spring set up for my 9mm AR PCC with a 5” barrel?
Use an RB5007 (Standard Damped) 9mm buffer and an extra power .223 carbine buffer spring such as the Sprinco Red. If you run it with heavy subsonic bullets and a suppressor, then you may find that a JP .308 carbine spring works and runs with less spring noise. If your gun happens to cycle on the soft side, then you can use the JP .223 carbine spring in order to get less spring noise. The JP .223 carbine spring is slightly less powerful than the Sprinco Red spring.
The JP .223 carbine spring is slightly less powerful than the Sprinco Red spring.
What is the best buffer and spring set up for my CMMG Radial Delayed Blowback 9mm AR PCC?
Use an RB5005 AR10 Carbine Buffer or RB5000HP High Pressure AR15 Carbine Buffer with a Sprinco Red AR15 Extra Power Carbine Buffer Spring.
What is the best buffer and spring set up for my 45 ACP AR PCC?
Use an AR10/A5 carbine buffer tube and use an RB5015HD High Damped 9mm Buffer, PCC Buffer Weight and a JP .308 rifle buffer spring.
What is a hydraulic buffer in an AR-15?
A hydraulic buffer in an AR-15 is a specialized component designed to replace the traditional buffer in the firearm's recoil system. As an expert in AR-15s, I can tell you that the primary purpose of a hydraulic buffer is to improve the overall shooting experience by reducing felt recoil, minimizing bolt carrier movement, and dampening vibrations.
The hydraulic buffer functions using a piston filled with hydraulic fluid, which compresses as the bolt carrier moves rearward during the cycling of the firearm. This hydraulic compression absorbs the energy generated by the recoiling action, reducing the force felt by the shooter and allowing for faster follow-up shots.
