Some pics on the way, lower is pretty much done now, was somewhat of a hassle to fit the selector switch. Used the pin from an iron airsoft MWS ambi selector and grinded it to the same specs as the RS selector switch pin. Worked out great, some minor filing on the trigger guard was required to align the holes for the screws, nothing major though and not visible when mounted on the lower.
Now its "just" the rethreading on the buffer tube thread left
Some parts on the parts, the modifications on the selector pin and then the lower.
Finally my MWS DMR build (semi locked high FPS), fielded for the first time this weekend and it sure did give the bolty snipers a run for their money xD
