Yankee Hill Machine - Barrel Shim Set 1/2" I.D. for 5.56mm

The primary function of the Yankee Hill Machine Barrel Shim Set is to ensure the correct orientation of a timed muzzle device. This is crucial for achieving optimal performance and alignment of the muzzle brake with the barrel. Proper alignment can significantly affect the accuracy and recoil management of your firearm, making these shims an essential component for precision shooting. The set includes various thicknesses to accommodate different alignment needs, ensuring a snug and precise fit.

The shims are made from durable stainless steel, which contributes to their reliability and longevity. Stainless steel is resistant to corrosion and wear, ensuring that the shims maintain their integrity even under harsh conditions. This durability is essential for maintaining consistent performance over time, especially in environments where moisture or other corrosive elements may be present.

Using a shim set with a 5.56mm Q.D. Muzzle Brake is important for ensuring the brake is properly timed and aligned.
