Looking for a tech to do some work on my G&G GR15. Trigger tends to get stuck when on semi and is only fixed when fired at full-auto then switched back to semi. Also was only shooting at 320 fps with .20's, would like to get that up to 350 at least. Only used it once but purchased used and previous owner never mentioned any issues or if any work was done on it. Blowback seems weak but not sure how strong that feature was to begin with. Any assistance would be appreciated, thanks. Located in Litchfield Park btw.
