Yankee Hill Machine Co YHM-9389-SS suppressor gas block 0.750 bore 4140 steel

YHM Suppressor Gas Block (YHM-9389-SS)

Yankee Hill Machine Co’s Suppressor Gas Block is built for shooters who want an affordable way to tune an AR-style rifle dedicated to suppressed use. It uses a reduced gas port (50% smaller than a standard gas block) to help decrease “port pop” and mitigate blowback to the shooter for a more comfortable suppressed shooting experience.

Because barrel gas port size, barrel length, caliber, suppressor design, and ammunition can vary widely, you may need to fine-tune the port size to match your exact setup.

Product Highlights

• Reduced gas port (50% smaller than standard) helps minimize port pop and gas blowback when shooting suppressed
• Designed for a host firearm intended to be shot exclusively with a suppressor attached
• Constructed from 4140 steel
• Mil-spec phosphate coating provides a rugged, corrosion-resistant finish
• May require port-size fine-tuning to match barrel, caliber, ammo, and suppressor variables
