- Slip-on moderator adapter for Air Arms S300, S400 and S410 with 10mm barrels
- Accepts any standard ½" UNF male-threaded moderator or silencer
- Approximately 55mm total length including the ½" UNF male thread
- Secured by two grub screws — adds approximately 15mm to overall barrel length
- Black anodized alloy construction for durability without excess weight
- Supplied with thread protector cap and Allen key
The Best Fitti slip-on moderator adapter lets you fit any standard ½" UNF threaded silencer to an Air Arms S300, S400 or S410 with a 10mm barrel. The adapter slides over the muzzle and is locked firmly in place by two grub screws, adding approximately 15mm to the overall barrel length. At around 55mm total length — including the ½" UNF male thread — it keeps the increase in overall length to a minimum while providing a solid, secure platform for your chosen moderator. Machined in black anodized alloy, the adapter is robust enough for regular field use without adding unnecessary weight. A thread protector cap is supplied to guard the ½" UNF thread when no moderator is fitted, and an Allen key is included for the grub screws. Straightforward to fit, this adapter is the tidy solution for Air Arms S-series owners who want to run a moderator for pest control, rabbit shooting or general plinking without permanent barrel modification.
