Strike Industries – AR Shim Set
- The Strike Industries AR Shim Set is a must-have for precision-minded shooters and builders who demand proper timing and alignment of their muzzle devices.
- Designed specifically for .223/5.56 (1/2″-28 TPI) or .308 (5/8″-24 TPI) threaded barrels, this shim set offers a dependable, reusable alternative to crush washers which can deform under torque and fail to provide consistent alignment.
- Ideal for applications where bore alignment and port positioning are critical, such as when mounting suppressors or compensators, these flat, high-precision shims ensure your muzzle device is securely and accurately timed.
- Each set includes a range of thicknesses to help fine-tune fitment without stacking multiple washers unnecessarily.
- Whether you’re building a new rifle or upgrading an existing one, the Strike Industries AR Shim Set gives you peace of mind with every installation no guessing, no warping, just precise, reliable alignment.
Features:
- Available in Two Sizes – Choose from 1/2″-28 TPI (.223/5.56) or 5/8″-24 TPI (.308) to match your barrel threads perfectly.
- Precision Timing Aid – Helps fine-tune the clocking of muzzle devices such as compensators, brakes, or suppressor mounts.
- Guaranteed Alignment – Ensures true bore alignment for enhanced accuracy and safety—ideal for suppressor and high-performance builds.
- Correct Port Orientation – Accurately position muzzle device ports to maximize performance and reduce muzzle rise.
- Reusable Design – Unlike crush washers, these shims retain their shape and can be used multiple times without loss of function.
