The “LH” signifies that the thread tightens by turning it counter-clockwise. This configuration has typically been chosen to forestall the muzzle machine from loosening as a result of rotational forces of the fired projectile.
1.5×24 mm Proper-Hand Thread (RH)
This thread pitch is changing into more and more frequent on trendy AK-47 patterns, and might provide extra potentialities for the varieties of equipment that may be hooked up. On this case, “RH” means the thread tightens by turning it clockwise.
Past the barrel, thread pitches can be discovered on numerous parts all through the AK-47. The trunnions, fuel blocks, and even some handguard retaining rings make the most of threads. For instance, the trunnions – the center of the AK-47 motion the place the bolt locks in place – typically have threaded holes for mounting numerous parts. Equally, the fuel block, chargeable for channeling gases to cycle the motion, might make the most of threaded screws or different fasteners. The particular thread pitches for these elements are sometimes particular to the rifle design and may not be interchangeable between completely different producers or AK-47 variants.
