Considerations & Trade-offs

  • This M5 .308 Carbine Buffer is specific to .308 carbines with a collapsible buttstock, so it is not a fit for .308 rifles with a fixed buttstock.
  • It will not work on AR15 platform firearms, which limits it to the intended .308 carbine setup.
  • The product is described as a shorter .308 buffer, so compatibility should be verified carefully before ordering for a build or replacement.
