Upgrade your AB Biller metal speargun with the Generic B11 Muzzle in metal construction. This replacement part is crafted for DIY builds and field repairs, offering a secure fit and dependable performance when you need it most.
The reinforced nylon body is built to endure saltwater exposure and repeated cycling, providing resilience without adding unnecessary weight. The muzzle’s profile is designed to help maintain a clear line of sight as you track fast movement through the water.
Whether you are rigging your first DIY build or performing on‑the‑spot replacements in the field, this muzzle offers versatility across a range of activities from casual spearfishing to more demanding freediving sessions. Its universal compatibility makes it a flexible addition to a diver’s toolkit.
In practice, a well‑fitting muzzle can contribute to steadier handling and smoother transitions between reloads, especially under variable currents. The part is designed to stand up to regular dives and travel, helping you rely on your gear when you need it.
Important: Please place plastic parts (muzzle, grip, butt) in hot water for approximately 10 minutes before assembling to avoid damage to the plastic.
Q: Is this muzzle compatible with AB Biller metal spearguns of all sizes?
A: The B11 Muzzle metal is designed to fit AB Biller metal guns across sizes; verify your model for a proper fit.
Q: Should I heat the plastic parts before assembling?
A: Yes, soak the plastic muzzle, grip, and butt in hot water for about 10 minutes to prevent damage during assembly.
