American Precision Arms Gen 2 Micro Bastard Self-Timing Brake - Stainless Steel, 1/2"-28 TPI Threads, 1.86" OAL, .750" Diameter for 30 Cal AR-Platform & Hunting Rifles

The American Precision Arms Gen 2 Micro Bastard Self-Timing Brake is a compact muzzle brake engineered for AR-platform rifles and bolt-action hunting rifles chambered in 30-caliber. Built from stainless steel, this brake combines durability with a self-timing design that eliminates the need for careful indexing during installation—thread it on and it locks into the correct position automatically. The compact 1.86" overall length and .750" diameter make it a practical choice for hunters and shooters who want recoil management without excessive muzzle signature or unnecessary bulk.

Stainless construction resists corrosion in the field and cleans up easily after shooting. The self-timing feature is a real convenience: no need to count flats, measure how the vents align, or make multiple installation attempts. Unscrew, level, done. For hunters running 30-cal AR builds or traditional bolt-actions, this brake delivers solid recoil reduction in a footprint that won't snag brush or complicate your profile.

Threading is 1/2"-28 TPI, the standard for most 30-caliber rifle barrels. If you're considering a brake for a modern AR or a precision hunting rifle, verify your barrel threads before purchasing—a shop can handle installation and timing if you'd rather not do it yourself.

Frequently Asked Questions

Will this brake fit my 30-cal rifle?

The Gen 2 Micro Bastard is designed for 30-caliber AR-platform and bolt-action hunting rifles with 1/2"-28 TPI threaded barrels. Verify your barrel threading before purchasing. If you're unsure, a gunsmith can confirm compatibility.

What does "self-timing" mean, and why does it matter?

Self-timing means the brake locks into the correct rotational position automatically as you thread it on. Traditional brakes require you to count flats or measure vent alignment to install correctly—extra steps that can lead to mistakes. This design eliminates that hassle.

Is this brake compatible with my AR-15 or other .223/5.56 rifles?

No. This brake is chambered and sized for 30-caliber cartridges. It is not compatible with .223/5.56 AR-15s or other non-30-caliber platforms.

How do I install this brake?

Thread the brake onto your barrel's 1/2"-28 muzzle threads until it seats firmly. The self-timing design means it will lock into the correct position automatically. If you're not comfortable doing this yourself, have a gunsmith handle the installation.
