The Kaw Valley Precision 13.5×1 LH to 1/2×36 Thread Adapter (brand part no. KVPADPT1313) converts a 13.5×1 left-hand muzzle thread, common on many AK-platform rifles, to the 1/2×36 pattern used by a wide range of muzzle devices and rimfire-adjacent accessories. Kaw Valley Precision machines this adapter to thread securely onto the factory 13.5×1 LH muzzle while presenting 1/2×36 threads on the front, letting owners run a broader selection of aftermarket muzzle devices than what’s built specifically for AK left-hand threading. It’s a simple, inexpensive way to expand muzzle device compatibility without cutting new threads on the barrel.

Frequently Asked Questions

Is 13.5×1 always left-hand thread on AK rifles? Many AK-platform rifles use 13.5×1 left-hand threading, but always confirm your specific rifle’s thread direction before ordering an adapter.

Will this fit a right-hand threaded muzzle? No, this adapter is machined specifically for 13.5×1 left-hand threads; a right-hand threaded muzzle needs a different adapter.
