Specna Arms Rra Sa-e11 Edge Double Loading

[Brye2112]

Hi all, 

Recently picked up a specna arms edge, works fine on full auto but when firing in semi it is double loading bb's and firing 2 at once. Tried with the supplied midcap, a ps midcap and marui hicap and getting the same result for each. Anyone any ideas? 

Thanks

Have you made any changes to the gearbox?  What battery are you using? What spring?  

2 complete cycles of the piston with 1 trigger pull, or 2 bb's loaded in the inner barrel?

I took the gearbox apart to give it a clean, no changes inside. Nuprol 7.4v 1450 lipo and stock spring that came installed in the rif.

Feels like 2 bb's loaded in the inner barrel

Check the tappet plate, nozzle, hop chamber and inner barrel, refit etc.  

Could be that first BB is getting stuck then the second is helping to push it out. Check the condition of the hop rubber.

Oh and check that your tappet spring is on correctly and in good strong condition.

So all parts appear fine. All fitted correctly, nothing worn. 

Gonna try an 8.4 nimh battery tomorrow and also try the other spring, see if any of it makes a difference
