Sniper qd flimsy and defective? - Sniper Heavy Duty Push Button QD Sling Swivels

Had finally put this on a qd mount that’s integrated within a slr ion ak rail, it’s quite wobbly while still being “secured”. When I was tilting the gun and fitting mlok accessories for the first time I had noticed what I assumed was a screw randomly fall out my gun; but closer inspection showed it was one of the small metal balls that makes up the quick detach. I have shoved it back in but I have no hopes that’ll it’ll retain itself.
