The Ultradyne Apollo Max 5.56mm compensator muzzle brake is engineered to tame recoil and keep your rifle on target through rapid fire. Built from 416 stainless steel with a salt bath nitride finish, this brake stands up to hard use in the field and won't let weather or carbon fouling compromise its performance. The 1/2"-28 thread pattern makes it a direct fit for most modern AR-15s and other 5.56 platforms, and the included timing nut simplifies installation while ensuring perfect rotational alignment with your barrel-mounted sights or optics.
Weighing just 5.2 ounces total, the Apollo Max extends 2.94" from the muzzle end of your barrel and won't throw off your rifle's balance. Ultradyne's design focuses on effective recoil reduction without unnecessary weight or unwieldy proportions—ideal if you're building or upgrading a carbine for faster target transitions or competitive shooting. The shrouded timing nut keeps the brake secure and makes timing adjustments straightforward if you ever need to remove and reinstall it.
This compensator is not recommended for barrels shorter than 16", so confirm your barrel length before ordering. If you're running a mid-length or rifle-length gas system with a properly sized barrel, the Apollo Max delivers the recoil control that keeps shots grouping tight when it counts.

Yes, if your barrel has a 1/2"-28 thread pitch (standard on most 5.56 and .223 AR-15s) and is at least 16" long. The design accommodates firearms with barrel-mounted front sights, so it will clear most sight configurations.
The compensator body weighs 4.4 ounces; the included timing nut adds 0.8 ounces, bringing the total installed weight to 5.2 ounces.
The shrouded timing nut simplifies indexing: thread the brake onto your barrel, align it as needed, and tighten the timing nut to lock the rotational position. This ensures consistent sighting geometry if you ever remove and reinstall the brake.
Ultradyne does not recommend the Apollo Max on barrels shorter than 16". Confirm your barrel length before purchase.
