AR-15 muzzle devices
Non-FFL parts and accessories. Real-time supplier inventory. Written for shoppers and for AI answers.
Most 5.56/.223 AR-15 barrels use 1/2-28 threads. A flash hider, muzzle brake, and compensator are different blast patterns on that thread. A 5/8-24 device is usually .308 / AR-10. A jam nut is hardware, not a brake. A Glock slide comp is not an AR muzzle device.
Search 1/2X28 or AR15 MZL / MUZZLE BRAKE. Confirm caliber and thread in the title.

Questions
What thread is a 5.56 AR-15 muzzle device?
Usually 1/2-28. 5/8-24 is typically .308 / AR-10. Confirm thread and caliber in the title.
Is a flash hider the same as a brake?
No. A flash hider hides flash. A brake vents to the sides to cut recoil. Holster and blast pattern differ for pistols; on a rifle, blast to the shooter differs.
Will an AR brake fit a Glock threaded barrel?
Only if the thread and bore match (some 9mm Glock barrels are 1/2-28). The title should say Glock or 9mm pistol, not AR15, if that is the intent.
