VLTOR A5 Buffer

A5 VLTOR Buffers



These buffers are designed specifically to complement the VLTOR Extended-Length Vltor A5 Rifle Recoil System. Manufactured in the USA by Heavy Buffers, not affiliated in any way with VLTOR.

We machine these from solid 303 Stainless Steel and include a Stainless Steel roll pin for a lifetime of trouble-free performance. The head is polished for an extra smooth finish that won't cause damage to your expensive buffer tube.


  • An H3 or H4 will work well for most applications.
  • If you shoot underpowered/import/surplus ammo an H or H2 might be a better choice.
  • If you are running a suppressor or want maximum recoil reduction you want the XH (10 ounce) buffer.


Wolff XP RIFLE buffer springs are recommended for maximum reliability.


H - 4.0 ounces - $55


H2 - 4.5 ounces - $60


H3 - 5.5 ounces - $65


H4 - 6.5 ounces - $75


XH - 10.0 ounces - $125

This kit includes an empty buffer body and various internal weights to allow 'tuning' the buffer to your specific firearm/ammo. Total buffer weight can be adjusted from 4.0 to 6.5 ounces, or up to 10.0 ounces with the optional Tungsten inserts, sold below. (Wolff XP Buffer spring is not Included.)

Tungsten Inserts - Set of Four - $55

Note: A5 buffers and springs are designed to work only in the Vltor A5 Recoil System.
