A while back i bought an Umarex MP5 off moonbuns
This came with a gas leak which was very generously reflected in the price .
i have finally got around to taking it apart to see what the problem was, i have heard the valve system on these are a right pain to repair
so didnt have much hope ... HOWEVER lady luck must have been smiling as i found out the valve is in tact and it was the piston seal that had blown apart.
still an awkward fix but i purchased a complete piston assembly including seal from Bagnal & Kirkwwod so im now waiting for delivery.
As this is made of plastic i found it to be a little underweight so i beefed it up by prizing the rear stock apart and filling it with Plastecine
I also filled the mag, handgrip and fore grip and im going to find a way to fit a fake suppressor.
just hope i can manage to reassemble it correctly and get it going.
