Added a small red dot to the GBB SD . Put a few mags through it yesterday and it shoots very nicely. Only did a rough hop set , but there is plenty of adjustment left so I can obviously go heavier than the .30's I run in all my GBB kit.
Chronod it , and it was a tad 'warm' that was outside with a mag that had been used once and refilled so the mag was cold and with red gas.
Fitted a spare restrictor disk that was in the draw and it was then at .90 j in a cold garage on green gas. So should be nicely skirishable at that. A warm mag or red gas will pop it just over the 1.0j mark . It's basically doing the same figures as my MP7 , so happy with that.
I plan to look at fitting a tracer unit into the front of the silencer, but will need to work out what length inner barrel I'll need as the existing one runs full length. That will be a project for over the winter, I'll run it as is for now.
Oh and ordered an AW drum mag for it from KY , will report on what that is like once it turnes up.
