The SP-A5 Spring and Buffer Kit includes everything you’ll need to outfit your rifle with VLTOR’s patented A5 Buffer System (aside from a compatible receiver extension tube).
The SP-A5 Spring and Buffer kit includes:
(1) “A5H2” A5 Buffer
(1) A5 Buffer Spring
(1) Vltor Lockplate
(1) Vltor Castle Nut
***The SP-A5 kit is designed for the VLTOR A5 system and is only compatible with other VLTOR A5 products. This SP-A5 spring kit requires the use of an A5 receiver extension tube. The physical dimensions of A5 buffer components are different than that of standard carbine or rifle buffer components. You cannot blend components from the different buffer systems. Doing so may result in injury or damage to your firearm. For additional information, please email us at TechSupport@Vltor.com
Many of VLTOR’s products are export controlled by the International Traffic in Arms Regulations (ITAR). Shipments from VLTOR may contain products controlled by the U.S. DoS or the U.S. DoC. Export of such items may not be done without prior approval from the U.S. Government and VLTOR.

1. Can I use this spring and buffer kit in a carbine receiver?
No, the SP-A5 spring and buffer kit is designed to only work with the A5 receiver extensions (RE-A5 and RE-10/A5SR). Attempting to use these parts in a regular carbine receiver extension will result in damage to the firearm and potential injury to the operator.
2. Can I purchase this kit with a different weighted A5 buffer?
We do not sell the spring and buffer kit with any other A5 buffer other than the standard A5H2 in “kit form.” But you can purchase all of the parts separately.
