“I don’t know how good Filipinos are at making guns,”
You will not believe this, but I was in Cebu city and Pangasinan a year ago (we have offices in Manila and i head there 2x a year), they have gunsmiths who can manufacture and copy semiautomatics within minutes. I saw it myself in Cebu and they made a copy of 50 caliber AND AR-15 which I tested myself. No misfire.
They are good!
