Here is the URL to the video of my son and I at Airsoft GI in Plano showing them our shield we built. I had told them about it during its construction, and they said bring it by when it was done. Hoping to use it at Dagestan event if possible.
You will probably be able to use it with some restrictions. What those might be I have no idea. I would say if you don't get an answer here then bring it to Dagestan and see what they say. Sorry I could give a definitive answer. I saw your vid and it looks super cool. Hope to see you there.
