While the original buffer is engineered for long service life, this spare allows you to refresh the striker assembly without replacing the entire unit.

FAQ
How often should I replace the buffer?
Under normal use, the Apex Durable Striker buffer does not require scheduled replacement. However, if you notice inconsistent primer strikes, unusual noise during cycling, or visible wear on the buffer face, replace it as needed.
Can I use this buffer with a factory striker?
No. This buffer is machined specifically for the Apex Durable Striker geometry. It will not fit or function with any factory striker, including FN, Glock, S&W, or other OEM units.
Does this buffer affect trigger pull weight?
No. The buffer only cushions the striker’s forward travel. Trigger pull weight is determined by the trigger mechanism and spring set, not the buffer.
