Some RAS are made with metric threads (for what guns exactly I can only recall as old Classic Army and ICS), while G&P, Systema and most others use an Imperial thread. In the past, I've used a metric thread file to re-work the threads enough to use those RAS with a gun that has Imperial threads. FWIW, real guns use an Imperial thread, and obviously real RAS will use Imperial threads also.

The thread pitch on the metric threads is 1.50mm/thread, so if you get a thread file at pretty much any place that sells tools, you'll be fine with that and about an hour of filing.
