Buffer Spring for AR-15/M16/M4 Carbine (True North Arms)

Buffer Spring for AR-15/M16/M4 Carbine (True North Arms)

  • 957

Yep it's a standard spring for your M4 carbine-style buffer. Some competitive shooters like to have a backup/spare in your range kit. If your AR is mysteriously malfunctioning, this may be one part to consider replacing.

Note this is not compatible with the A1/A2 fixed stock that uses a longer buffer. Fits in either mil-size (1.15") or commercial size (1.17") buffer tubes; the spring is the same for both.

You get:

  1. Standard buffer spring

Compatible with:

  • Standard spec AR-15/M16 carbine buttstocks
  • Mil-spec or Commercial-spec buffer tubes

Installation Difficulty:

Tools required: None, the spring can be accessed by simply releasing the buffer and spring from the Lower Receiver.
