Yankee Hill Machine YHM-3250 Sidewinder 5/8x24 Direct Thread Adapter

The Yankee Hill Machine YHM-3250 Sidewinder Direct Thread Adapter converts a YHM Sidewinder, Cobra M2, or Cobra suppressor from its quick-detach mounting system to a fixed 5/8"-24 direct-thread configuration. The 5/8x24 thread pitch matches the standard muzzle on most AR-10 and .30-caliber rifle barrels, giving you a secure, repeatable mount on hosts where a QD interface is not required.

Machined from 17-4 PH stainless steel with a black oxide finish for corrosion resistance and long service life, this compact adapter measures just .375" long with a .735" diameter and weighs only 1.86 oz, adding minimal weight and length to your suppressor setup. The YHM-3250 is the factory-direct thread adapter for fixed-mount applications on 5/8x24 threaded hosts running a Sidewinder, Cobra M2, or Cobra suppressor.
