ATI Outdoors Shark Muzzle Brake — Black Oxide Steel — 1/2"-28 TPI — For .223 Rem / 5.56 NATO AR-15 — A5102251 (UPC: 758152771094)
Tame recoil and add aggressive style to your rifle with the ATI Outdoors Shark Muzzle Brake. Precision-machined from heat-treated steel and finished in a durable black oxide, this brake uses the most common 1/2"-28 TPI thread for .223 Remington / 5.56 NATO AR-15 platforms. Purpose-built porting helps reduce felt recoil and muzzle rise, keeping your sight picture flatter for faster follow-up shots, more stable transitions, and improved control from bench to barricade.
Why Choose the ATI Shark Muzzle Brake?
Effective Recoil & Rise Control: Multi-port baffles redirect gases to counter rearward impulse and muzzle climb—ideal for faster splits and steadier strings.
Aggressive “Shark” Profile: Distinctive, serrated front adds a bold look that complements modern AR builds.
Black Oxide Steel: Tough, corrosion-resistant finish over a robust steel body for long service life and consistent performance.
AR-15 Standard Threads: 1/2"-28 TPI fits most .223/5.56 barrels for easy compatibility and hassle-free upgrades.
Range-Ready Durability: Built to handle high round counts and training days without losing its edge.

Key Features & Benefits
Flatter Shooting: Port geometry mitigates muzzle rise so you can keep optics on target, helping accuracy and speed in practical carbine drills.
Faster Follow-Ups: Reduced recoil impulse promotes better shot-to-shot cadence for competitions, classes, or defensive practice.
Consistent POI: Rigid steel construction maintains repeatable alignment for predictable point-of-impact after installation.
Clean Aesthetics: Low-glare black oxide pairs with nitrided or parkerized barrels and most modern finishes.
Easy Maintenance: Non-porous finish wipes clean after carbon builds up; no special tools required for basic care.
Ideal Use Cases
Range & Training: Improve split times and control during high-tempo carbine courses.
3-Gun / Competition: Keep the dot or reticle flat for faster transitions between targets.
General Purpose ARs: Add durability and recoil control to duty, ranch, or home-defense carbines (where lawful).
Compatibility & Fitment
Fits: Barrels threaded 1/2"-28 chambered in .223 Rem / 5.56 NATO (standard AR-15 pattern).
Does Not Fit: Non-1/2"-28 threads or larger calibers (e.g., .30 cal); always confirm your barrel thread and caliber.
Timing: Most users will time the brake so ports are oriented correctly; use included or aftermarket shims/crush washer as needed per best practices.
Installation Notes
Safety First: Verify the firearm is unloaded and remove the magazine; visually/physically check the chamber.
Remove Existing Device: Loosen and remove any old muzzle device and washer.
Prep Threads: Clean barrel threads; apply a small amount of high-temp, non-permanent thread locker if recommended.
Time the Brake: Install with a crush washer or shim kit to align the ports properly; torque to manufacturer guidance.
Function Check: Confirm clearance with handguards and verify bore alignment before live fire.
Pro Tip: If you’re new to muzzle device installs, consider a gunsmith for perfect timing and torque—especially on thin or lightweight barrels.
Care & Maintenance
Wipe exterior with a soft cloth and firearm-safe cleaner.
Periodically remove carbon from ports; avoid harsh abrasives that could mar the finish.
Re-check torque after the first range session and after heavy round counts.
Legal & Range Etiquette
Regulations vary. Check all local/state/federal laws regarding muzzle devices and overall rifle configuration.
Muzzle brakes can be loud and increase side blast—use hearing/eye protection and be courteous to adjacent shooters.
FAQ
Will this fit my AR-15?
If your barrel is .223/5.56 and threaded 1/2"-28, yes. Always verify markings on the barrel shoulder.
Does it require a crush washer?
Most brake installs use a crush washer or shim kit to time the ports correctly. Follow best practices or consult a gunsmith.
How much recoil reduction should I expect?
Results vary by rifle, ammo, and shooter, but users generally report noticeably flatter tracking and quicker follow-up shots versus an A2 flash hider.
Can I use this with a suppressor?
This is a muzzle brake, not a suppressor mount. If you plan to run a can, use the manufacturer’s compatible mount.
