I, for one, am sad to see them go. When I was stationed at McChord AFB, and later when TDY there, I visited Olympic Arms. They were kind enough to show me through their entire operations... from the machining of their lowers and uppers, to their lathes where they created the barrels, assembly, the works. The folks were beyond nice. They took really good care of all the guys I knew who went in there.
As for their product, in the last decade I thought they put out some pretty good stuff for the price point. No, they were not LWRC, or LMT, or Noveske, but then you were not paying LWRC, LMT, or Noveske prices. Their creation of 22-250 and WSSM uppers were pretty ingenious. If it wasn't for the failure of the WSSM cartridges to stick (which is not their fault), I would view those options as a surefire way to get .243 and near 25-06 power out of an AR-15-sized lower, avoiding the weight of the larger AR-10 class.
Sure, their cast lowers were a problem a long time ago, but companies make mistakes and move on. As for their pistols in 7.62x39 and ensuing ATF issues, this is the first I have heard about it. How long ago was that? But haven't other companies done stupid things in the past? Ruger? Colt? Come on, gotta let things go! As was also said, if you don't like the laws, have you met with/written your congressman/woman or senator about changing them?
To echo smee's remarks, I see this as another group of Americans now out of a job... Not like there are a bunch of AR manufacturers in the Tacoma-Olympia area for them to move to! Then again, I wonder how much the ultra-left/anti-gun leaning area they are in contributed to their closing! Maybe Scorch could shed some light on that...
