After years of use, the buffer spring on your rifle may stress, and you'll possibly notice an increase of misfeeds on your AR-15.  The answer to the problem may be as simple as replacing your carbine's buffer spring.  The buffer spring controls the bolt carrier assembly's forward action, which picks up another round after firing.  If that spring gets stressed, it may not respond with sufficient energy to push the bolt carrier group forward enough to chamber a round.

  • Type: AR-15 Mil-Spec

As any high-volume or competition shooter of an AR-15 style rifle will tell you, whatever moving parts your rifle has will need maintenance over time.  FN America understands this better than most and offers various replacement components to keep your rifle at an optimum performance level.  FN America features this Mil-Spec Carbine Buffer Spring for replacement made from durable steel.  When you do a deep clean and maintenance on your AR-15, or you're into building an AR-15 from the ground up, you'll want to purchase an ample supply of these buffer springs.
