Ares UMP 45 Blowback Fix?

[ieuanam]

So my blowback has finally broken which means its a time to upgrade. My question is, how can I disable the blowback and stop the plate from sliding back due to gravity? When I mean it has failed, I mean, the blowback still pushes it backwards but the string has gone so it cannot push itself forward again

Contact ares themselves.  Both my return springs snapped so the mock bolt wouldn't return forward. For £11 I managed to get 2 new springs shpiped out to me. Most of the cost was the shipping cost.
