It's understandable that a fellow S&W M&P 15 owner from California is a bit agitated. They have to live with that horrid bullet button & mags limited to 10rds. That's the price they pay for having decent year round weather.
All good-natured ribbing aside, the firearms laws in California are sure odd. I thought I had it bad here in NW Illinois, close enough for City of Chicago anti-gun sentiment to leak into the suburbs.
