Alex's Review of NEMO Arms .300 Blackout Custom Carbine Buffer Spring

I have been playing with my AR components to get subsonic ammo to cycle correctly. I have an adjustable gas block and had my gun cycling fairly reliably except no lock back. I was still getting stove pipe jambs if the gun got dirty at all. With this spring and an H3 weight I was able to adjust the gas block and get great cycling reliability and full lock back.
Pros:
  • Works great and as advertised

  • None
