Yes.
I had the same issue after 2 years on the stock sears.
Basically at one point the hammer rides the bolt, and releases just enough gas to jam the BB in the hop-up lip. The valve says half open and spews the gas.
Everything was working fine when outside the gun.
I swapped my whole trigger unit to see if it made a difference and it did.
Then swapped back and forth to find that the sears where just a bit too worn.
