Precision Armament M4-72 Severe-Duty
Aggressive two-chamber muzzle brake that consistently ranks among the most effective recoil reducers on 5.56 carbines. Loud and with heavy side blast, so it suits competition and range use rather than teams. Threads onto 1/2-28 barrels.

Every firearm this threads onto, resolved
Not a list the maker typed out: the answer comes from the interface this part needs and the mounts each firearm exposes, so it stays right when either one changes.
- The reverse lookup on every part in the catalogue
- Interface standards, platforms and fit overrides
- The same answers through the API and the MCP server
Requires a signed-in GunSpec account on the Studio plan. The answer is computed per firearm, so it is not part of the public record.
