Product Overview
Lot of 3 replacement magazine O-rings designed specifically for FX 8-shot magazines used in FX-manufactured pre-charged pneumatic (PCP) rifles. Compatible with both .177 (4.5mm) and .22 (5.5mm) calibers, these O-rings restore reliable magazine feed and improve seal integrity for consistent shot-to-shot performance.
Material & Performance
- Durable elastomer: Formulated to resist compression set and maintain elasticity through repeated loading cycles.
- Precision fit: Matches original magazine groove profiles for smooth installation and secure seating.
- Optimized for PCP use: Designed to handle the low-pressure seal environment of FX magazines without swelling or tearing.
Installation & Maintenance
- Before fitting, inspect the magazine feed lips and internal surfaces for debris or burrs.
- Apply a very light smear of silicone-based lubricant to the O-ring to ease installation and improve sealing — avoid petroleum-based greases that can degrade elastomers.
- Replace O-rings at the first sign of cracking, flattening, or reduced magazine feeding reliability.
Compatibility Notes
These O-rings are designed for FX-manufactured magazines and will fit FX models listed above as well as FX-made rifles branded by RWS, Webley, and Logun where the 8-shot magazine geometry matches. Always verify fitment by comparing the original magazine O-ring size and profile before purchase.
Packaging & Guarantee
- Sold as a pack of 3 O-rings — ideal for keeping one on-hand as a spare.
- Each O-ring is inspected prior to packing for consistent quality.
- Satisfaction guarantee: If parts arrive defective or do not fit, contact us for replacement or refund.
