If it's like 7.62x51, the blanks for grenade launching are hotter and not to be used with blank firing attachments.
These use a standard rifle cartridge.

It’s the bipod mounting stud. That’s a Colt HBAR m16, the model 606A.
Special grenade cartridge, you can use a regular blank but range is very limited, as an example with 30-06 using a regular blank you will get about 50 yards, with grenade cartridge you get up to 175 yards. A 5.56 regular blank would likely cause a "Hoist with his own petard" scenario.
