Description

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).

  • (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 a 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.

  • VLTOR A5H2 (5.3oz) standard weighted buffer included
  • Receiver locknut has three notches for staking

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.

Solid Product, Great Seller

I think VLTOR products generally speak for themselves. Great fit and finish, exceptional quality.

This was part of my first order from Milspec Retail, and color me impressed! Shipping was exceptionally fast, and the items were packaged very well and protected during shipping. I will definitely order more from them in the future.
