*Our barrels are ported conservatively. Paired with a heavy buffer, you may experience stoppages with underpowered steel-cased ammo. To guarantee reliability with all ammo types, use a standard carbine buffer + spring & run the system with a magazine of full power M193/M855, if new, before shooting steel. After an initial 30rd break in, steel-cased ammo can be used without issue.

This barrel is classified as an HBAR Barrel.
