Vltor A5 Recoil System Spring and Buffer Kit AR-15 Carbine
The Vltor A5 Recoil System was developed at the request of the US Marine Corps as a potential future upgrade to replace the current A2 Fixed Stock used on the M16A4. The new recoil system consists of the Longer A5 Receiver Extension Tube with 7-Positions, a Longer and Specially Weighted A5 Buffer, and a standard Rifle Length Buffer Spring. The A5's enhancements to the AR-15 operating system result in a rifle that exhibits the increased Reliability, Smooth Action Impulse and Performance for which the A2 Fixed Stock Assembly is renowned, while also offering the benefits of Full Adjustability and greater Ergonomics attributed to the M4 Collapsible Stock arrangement. The A5 Recoil System is compatible with both direct gas impingement and piston operated AR-15 platforms, and may be fine-tuned to alter a rifle's recoil impulse or cyclic rate by changing to a different weight A5 Buffer (5 weights available).
NOTE: The A5 Spring and Buffer Kit is just one part of the proprietary Vltor A5 Recoil System that is only compatible with the Vltor A5 Receiver Extension Buffer Tube (Product# 348-370). Attempting to use these components with Any Other AR-15 Carbine or Rifle Length Receiver Extension Buffer Tube Will Result in Damage to the host firearm.
