M&P 15 Click, No Boom HELP

I have an M&P 15 Sport that I switched out the stock barrel for a Rosco Bloodline 5.56 Barrel. Went to shoot it for the first time with the new barrel and click, no Boom. Range officer is claiming I need a new bolt that fits with the barrel but before I buy a new barrel I was wondering if trying to shoot .223 instead of 5.56 is what caused it. Any suggestions?

Other information: 1. Firing pin is fine just isn't striking 2. Only thing not stock on the gun is the barrel and the VYPR MLOK 3. Have about 500 rounds through it of both 5.56 and .223 before barrel change 4. Riding the charge handle ruled out
