The SF-BUFFER-H9 is designed primarily as a solution for fixed-gas, short piston M4 Carbine or equivalent weapon systems with cycling issues when firing. The additional mass of this predominately tungsten buffer allows for better cycling of the carbine when firing suppressed. The product can also be used with AR10 weapon platforms when additional mass is needed for proper cycling.

Features:

• Eliminates cycling issues on fixed-gas, short-piston rifles and carbines
• Increases weapon reliability when firing suppressed
• Can also be used on AR10 weapon platforms
