AB SUPPRESSOR
The AB Suppressor Muzzle Thread Adapter M18X1.5 is a precision-machined adapter designed to connect your suppressor to firearms with M18x1.5 muzzle threads. If you're running a suppressor setup and need a reliable interface between your can and barrel, this adapter ensures your suppressor sits true to the bore—critical for both accuracy and longevity of your equipment.
This isn't a generic off-the-shelf piece: the M18x1.5 adapter is engineered so that all mating surfaces are finished in a single machining operation. That single-process approach means the seating surfaces are perfectly aligned and concentric with the bore axis, eliminating the misalignment that can throw off your zero and accelerate wear on suppressor internals. It's the kind of detail that separates quality suppressor hardware from something that merely screws on.
Whether you're building a suppressed hunting rifle, setting up a precision shooter, or integrating a can into an existing barrel, compatibility is everything. If your rifle or upper receiver is threaded M18x1.5, this adapter gives you a clean, repeatable connection point for your suppressor. Before ordering, confirm your barrel or muzzle break is indeed M18x1.5 threaded—it's a metric thread found on some European and specialty firearms, not the common 5/8x24 or 1/2x28 you might be used to.
| Thread Size | M18x1.5 |
| Brand | AB Suppressor |
| Type | Muzzle Thread Adapter |
This adapter provides the M18x1.5 connection point on the barrel side. Your suppressor must have a compatible bore-threaded interface to accept it. Check your suppressor's specs for the correct internal thread size.
M18x1.5 is a metric thread found on select European rifles and specialty firearms. It's less common than 1/2x28 or 5/8x24 in the US market. Verify your barrel or muzzle device is threaded M18x1.5 before purchasing.
Finishing all contact surfaces in one setup keeps them concentric and perfectly aligned. This ensures your suppressor sits true to the bore, supporting consistent accuracy and reducing wear on suppressor internals.
