Tac-41 Medusa Hop wheel

An excellent quality hop wheel from Hadron Airsoft Designs & SniperMechanics.

Has a finer click than the stock Tac-41 hop wheel so allows for finer adjustment.

From the manufacturer:

The Medusa system is a fine pitch hop wheel conversion for the Tac41. Suitable for AEG and GBB Silverback hop units.

Medusa consists of a fine pitch adaptor, high tensile fitting hardware, and the laser engraved tactile adjuster wheel which uses the stock silverback detention ball bearing. The tactile feel of the Medusa is simply amazing, and intuitive. It's useable with bare hands to the leafiest ghillie gloves, yet still unobstructive to scopes.

Medusa conversion fits in seconds, removes in seconds, and can be removed if needed without upsetting the hop setting. Works fantastic with the stock Silverback nubs, the Chubb nub, and the Hadron Tac Nub.

Medusa applies pressure to the nub from directly above, and not from one side or angle. This flat pressure approach leads to more accuracy in BB trajectory, and tighter grouping at longer ranges. This must be one of the simplest upgrades for the Tac41 sniper series.
