Yankee Hill Machine
The Yankee Hill Machine Co Black Suppressor Gas Block is built for AR shooters who want to optimize their setup for suppressed fire without breaking the bank. Unlike a standard gas block, YHM's design features a gas port that's 50% smaller, which significantly reduces the "port pop" and blowback that can make shooting with a can uncomfortable or unpleasant. If you're running a suppressor on your AR and tired of getting hammered by excess gas, this is the tuning tool that makes a real difference downrange.
Since every setup is different—barrel length, caliber, suppressor model, ammo, and even individual barrel gas port size all play a role—YHM engineered this block to allow fine-tuning. You may need to dial in the port size to match your exact rifle and suppressor combo, but that's actually a feature: you get the suppression performance you want without over-gassing or under-gassing your gun. Built from 4140 steel and finished with mil-spec phosphate coating, it's made to handle the abuse of regular shooting and last.
This gas block is engineered for dedicated suppressed-host rifles—guns you'll run with a can attached most or all of the time. If you're building or tuning a precision AR for hunting, tactical practice, or just quieter shooting at the range, the YHM suppressor gas block is a straightforward, no-frills solution to tame blowback and improve the shooting experience.
| Material | 4140 Steel |
| Finish | Mil-spec Phosphate |
| Bore Diameter | 0.750 inches |
| Length | 0.95 inches |
| Weight | 1.6 oz |
| Port Configuration | 50% smaller than standard gas block |
The Yankee Hill suppressor gas block is designed for AR-platform rifles running a suppressor. However, because gas port size, barrel length, caliber, suppressor design, and ammunition all affect tuning, you may need to fine-tune the port size to match your specific setup. It's built for rifles dedicated to suppressed shooting.
Due to variations in individual rifle setups, some tuning may be required. YHM's reduced 50% port gives you a starting point; you may need to adjust it to eliminate port pop and over-gassing on your particular gun.
The bore diameter is 0.750 inches. Confirm this matches your AR barrel before purchasing.
This gas block is designed for rifles that will be shot exclusively with a suppressor attached. It's optimized for suppressed shooting and not recommended as a general-purpose gas block for guns used both suppressed and unsuppressed.
