Tm AEP Usp No Longer Feeding Bb's

[Groot]

Hello,

Hope someone can give some ideas on what to try. 

TM AEP USP suddenly stopped feeding bbs.

BB's are of a high quality,
Mag has been cleaned and lubed,
Barrel is clear and air can be felt coming out,

Fired on every hop setting, it just won't pick up a round.

Having stripped the top section, I can see the round bobbling about when the trigger is pressed, this round drops out when the magazine is released.

Airsoft Guru's, the floor is yours. 

I thank you

Either the magazine spring has lost too much tension over time or the nozzle/tiny-weeny-tappet has bought the farm.

Most likely the 2nd
