PKM-AR 5.56 with Beta-C mag, Suppressed, and Super Safety trigger.

I built this PKM using surplus PKM parts and the cheapest AR I could find. I bought an Anderson Arms AR-15 for $$299 to use for parts. This 5.56 PKM uses an AR operating system salvaged from the Anderson Arms AR-15. It is shown with an old police surplus Beta-C mag and suppressor. The suppressor is direct thread and held in place by a retracting pin like the AK-47 brake.
