For use with AR-15's using an A5 or Rifle Length buffer system and our Gen 2 AR-15 Flat Wire Spring.
Using our Gen 2 AR-15 Flat Wire Spring in an A5 or Rifle Length buffer system alone will yield suboptimal spring force on the BCG due to the longer length of those buffer systems when compared to Carbine Length buffer tubes. This spring spacer, when used with our Gen 2 AR-15 Flat Wire Spring in an A5 or Rifle Length buffer system, will mirror the performance of our Gen 2 FWS used in a Carbine Length buffer tube.
To install, drop the spring spacer into your A5 or Rifle Length buffer tube first. Install the Gen 2 FWS and buffer over the spacer. Use the appropriate A5 or Rifle buffer for your buffer tube.
DO NOT USE for AR-10/SR25 applications or with any other brand of recoil spring. Irreparable damage will occur.
