Strike Industries Mccircle Micro Threaded Compensator Steel 1/2"X28 Threads

The Strike Industries Mccircle Micro Threaded Compensator is a compact, minimalist muzzle device engineered to reduce felt recoil and muzzle rise on pistols equipped with 1/2"x28 threaded barrels. Originally designed for micro, sub-compact, and compact slides, the Mccircle's sleek profile redirects gas efficiently while maintaining a footprint slim enough to work with most production and aftermarket holsters—making it a practical choice whether you're running a carry gun or a range-focused build. Strike Industries' internal testing has shown typical recoil reduction in the 8–15% range, depending on your specific setup and ammunition.

Built from AISI 1144 steel and finished with a Quench Polish Quench (QPQ) process, the Mccircle tips the scales at just 16.3mm in length and minimal weight. The included O-ring system helps with timing and retention, and three spare O-rings are in the box. Because the Mccircle does reduce slide energy, recoil spring tuning may be necessary to ensure reliable cycling; this is a detail worth discussing with a gunsmith during installation. If your barrel lacks a shoulder, the O-ring method won't work—you'll need to secure the comp with red threadlocker instead.

This is a precision component that demands professional installation by a certified gunsmith and proper function testing before use. Treat it as part of your routine maintenance schedule, and inspect it regularly to ensure it remains secure and serviceable.

Frequently Asked Questions

Will the Mccircle work on my carry gun?

Yes—the Mccircle is compact enough (16.3mm) to maintain holster compatibility on micro through full-size pistols. Its minimalist profile is designed to work with most production and aftermarket holster systems, making it suitable for carry setups as well as range builds.

What do I need to do to install it?

Professional installation by a certified gunsmith is required. Installation must include proper function and safety testing. If your barrel has a shoulder, use the included O-ring for timing and retention. If your barrel has no shoulder, use red threadlocker (applied appropriately—not excessively) to secure the compensator. Recoil spring tuning may be necessary after installation.

What's included in the box?

You get one Strike Micro Threaded Comp—CIRCLE and three spare O-rings for timing and retention.

Does this work on barrels without a shoulder?

The O-ring timing system will not function on barrels without a shoulder. In that case, you must use red threadlocker to secure the compensator to the barrel, applied in an appropriate amount. A gunsmith can advise on the best approach for your specific barrel.
