How to Load & Use (Quick Guide)
Inspect pellets: Choose undamaged skirts; keep fingertips dry and clean.
Pre-index if required: Follow directional arrows/marks; preload spring tension per your rifle’s manual.

Install the mag: With the rifle safe and unloaded, insert per the owner’s manual until positively latched.
Function check: Cycle the action to verify smooth indexing before live fire.
Care & Maintenance
Keep it clean: Tap out debris; wipe with a soft cloth. Avoid petroleum solvents that can affect plastics or seals.
Go light on lube: If needed, a tiny touch of silicone-safe lube on the spindle—never on the pellet path.

Rotate service: Mark your magazines and rotate usage to even out spring wear.

Frequently Asked Questions
Q: Will this magazine fit my .177 air rifle?
A: It’s for platforms that use the S/Roto Index system. Check your rifle’s manual or retailer listing for model-specific compatibility.
Q: Which pellet profiles feed best?
A: Most domed, wadcutter, and hollow-point pellets work well. Extra-long or unusually shaped pellets may reduce capacity or hinder rotation.
Q: Do I need to preload the rotor spring?
A: Some rifles require light preload. Follow your manual to prevent misfeeds and undue wear.
Q: Can I store the mag loaded?
A: For maximum spring life, store unloaded between sessions. If staging loaded mags, rotate which mag you leave under tension.
Q: What if indexing feels gritty?
A: Remove the magazine, clear debris, confirm pellets are flush, and avoid forcing rotation.
