G&g gc4 g26 30th anniversary

[Shamal]

Bit of a strange one this.

Have stripped gun and overhauled gearbox,lubed and reassembled.New ally nozzle fitted.

Cleaned barrel and renewed all hop parts. 

Put gun back together and run it through the chrono. This is where it gets weird. 

Gun was reading around 178 to 208 fps on 0.2 with a m100 spring and it was firing one bb and missing one.

I think that's feckin' mad, what's wrong?

I carried on firing through the chrono and suddenly it was giving a reading of 344,344,333,338,344... and no missed shots.That's when I noticed that the mag was resting on my leg.

When I held gun with no pressure on mag it returned to low fps again and alternately firing one and missing one.

I discovered that if I held gun upside down it fired faultlessly and with a very good(344....) fps.

I can't figure it out 🤔

Any ideas?

Thanks
