Optimized Mamba Ø40 mm sound moderator: bigger, quieter, and lighter.
Equipped with several optimized chambers, this silencer is compatible with calibers 4.5 mm (.177), 5.5 mm (.22) and 6.35 mm (.25).
Its baffles play a key role in noise reduction, forming decompression chambers that slow down and dissipate the gases expelled when firing, while preserving shooting accuracy.
Designed for barrels with a 1/2 UNF male thread.
Be sure to check your thread before ordering. If in doubt, send a message with the name of your weapon.
For those who regularly disassemble and reassemble their silencer, adding the aluminium adapter, available in the shop, is a practical option. It allows you to preserve the 1/2 UNF thread of Invent3D sound moderators and facilitates repeated handling while ensuring a reliable and durable attachment.
