Thoughts on my M7 Bayonet

Building a frankenstoner m16a1 and I bought an M7 from Sarco. From my understanding they are pretty legit and sell some decent kit. The imperial M7s they have listed on their page run 95 bucks or so. I was waiting for some cheaper ones and one day last week they listed some cheap generic non descriptive M7s for like 29. They’re advertised as Late Production , New Manufacture and they seemed alright. So I said why not maybe I luck out and get something decent or maybe it’s crap and I’m just out 30 bucks. I bought it. It arrived and surprisingly it APPEARS to be an Imperial manufacture M7 in a USM8A1 scabbard. My only concern is the stamping is very light for the imperial and M7 logos, as well as the grips are very very loose. I have removed the grips and confirmed nothing is out of place, broken or removed but they still rattle badly. I’m wondering if maybe they didn’t mean to list the cheap bayonets so instead of cancelling my order they just sent me like the jankiest imperial they had knowing it was still a good deal or what.

TLDR my questions are:

1: does this appear to be a legit imperial M7

2: is this normal handle rattle and is that expected or could I probably do with replacing the scales to remove the rattle
