I recently started with airsoft. To that end I purchased a used G36 for a good prices as a project gun to familiarize myself with maintenance and modifications to an airsoft gun and the associated gearbox. I've had some issues with opening, shimming, etc. which the guides on these forums have been very helpful. However I haven't been able to find anything with the search feature with this particular problem. Safe works great. Semi works great. However the gun will not shoot in full auto. 1. When the selector plate is slide fully to the right, the cut-off lever does not move. The ramped up portion of the selector plate does not touch the cut-off lever. I believe I need to simply replace the cut-off lever with something like: http://www.airsoftgi.com/product_info.php?products_id=4275 which has an extra portion on the underside of the disconnector nub to contact that ramped portion. Is there a different approach I should be considering? 2. Now the interesting bit. If I manipulate the cut-off lever to the position where it would be under full auto, the trigger mechanism doesn't contact the trigger trolley, thus it isn't slid forward to connect the trigger contacts. I'm looking for a place to start troubleshooting this particular problem.
