Description
These spare buffers are designed specifically for use with the Apex Durable Striker. At just $6 each, they provide a low-cost way to keep your striker system running smoothly over the long haul.
While we have yet to wear one out or damage one during testing, we understand that shooters put rounds downrange. Whether you log high round counts at the range, carry daily, or hunt hard, having a spare on hand means you can swap in a fresh buffer without downtime. This is a simple, practical part to stock in your range bag or parts bin.
Important fitment note: These buffers are built exclusively for the Apex Durable Striker. They will not fit or function with the Apex HD Striker or any other striker on the market. You must use them with the Apex Durable Striker to ensure proper performance and reliability.
Specs:
- Replacement buffer for Apex Durable Striker systems
- OEM-spec dimensions for direct drop-in fit
- Durable polymer construction for consistent cycling
- Simple installation — no special tools required
Real-world benefits for the practical shooter:
- Cost-effective maintenance: Replace a worn buffer for only $6 instead of buying a whole new striker assembly.
- Concealed-carry readiness: A fresh buffer helps maintain reliable striker engagement and trigger reset on your carry gun.
- Hunting reliability: If you’re putting hundreds of rounds through your hunting rig in a season, a spare buffer ensures your striker stays consistent.
- Range efficiency: Swap buffers between sessions to keep your Apex Durable Striker performing at its best.
This part is listed under the FN category trail: Fn, Apex Durable Striker. If you run an Apex Durable Striker in your FN pistol, this is the only buffer that fits. Keep one in your spare parts kit, or grab a few to share with shooting partners who run the same setup.
No frills, no hype — just a solid, affordable replacement part that does exactly what it’s supposed to do.
