A set of calipers snugged up in the lower receiver pocket (where the handguard nub inserts) would confirm/deny. I'm interested, so long as it's a 1mm receiver gun. If you're ok with meeting up sometime this week I can bring a digital caliper and check it out.
Edit to add: It looks like a 1mm gun too, based on the dimples, but I'd still like to double check.
