Aero Precision 14.5 Pin and Welds Available!
Pin and welds are sweet… until you want to change the gas block. Aero Precision has solved that problem by equipping their P&W uppers with a turned down Epsilon 556SL muzzle brake.

As equipped, feel free to swap your gas block to your hearts content. The heart wants what the heart wants. Typically oxygen and nutrients, I reckon.
Check out AP’s new uppers here. 15% off for a limited time when you throw one it your cart.
