No barrel nut or hardware - TRYBE Defense AR-15 Magnesium Alloy Ultra Function Lightweight M-LOK Handguard w/ Full Top Rail

When I received it it was just the hand guard and it’s seems good but can’t us it since there is now hardware or barrel but I let optics planet know and they said they can’t get the parts from the company even though it’s an optics plant house brand I believe so it weird I feel like I was blown off they told me to just return it so I am delaying my build even longer also they sell the barrel but separately I don’t know why they couldn’t just send me one
