MP5K Loose Body Pin

[CzechMeOut]

So I had a magazine adapter jam inside the magwell of my CYMA MP5k.

Removed it but now the body pin is very loose which it wasn't before.

The little brass cyclinder that goes through the mag release catch falls out when it never did before.

I can put it all back together OK and the mag release works, however the pin is very loose.

Has something fallen out that I've missed?

Can anyone take a quick look at their MP5K please?

Thanks!

I’m pretty sure The brass cylinder is held in place when you put the lower receiver back on ✌?
