I am about to buy a Olympic Arms AR-15 chambered in 9mm. Is Olympic Arms a reputable firearms maker? How is their quality, service, fit and finish, etc.....
Haven't shot the Olympic Arms but I just picked up an American Spirit in 9mm. Your gonna love that rifle. They are a hoot to shoot. Most indoor ranges allow them which means the fun doesn't stop in the winter. Looking at your location that's probably not an issue.
9mm AR mags are getting tough to find and expensive. What does the Olympic come with? For $30 CDNN has the 40 round Argentine mags. I bought 3 and they work great in the ASA.
Good luck with the new rifle. Be sure to let us know how you like it.
Take Care
The Olympic Arms 9mm AR-15 uses Sten gun mags which are very cheap. Along with the Sten gun mags a "SOCOM block" is required which fits inside the rear portion of the magazine well.
