Here in the failed Socialist State of Calizuela, by law we're not permitted to have standard capacity magazines. We're limited to 10 rounds. This evening I swapped out my Magpul SOE-SL collapsible stock for an SOE fixed, swapped out my Magpul pistol grip for a "finned" non-pistol grip with a right side "thumb rest", and replaced the birdcage muzzle device with a "thread protector". Oddly, muzzle brakes are still acceptable...but horrendously loud even with a 5.56 to anyone to the left or right of the shooter. The supplied crush washer was way out of time and I couldn't find my peel washers so the muzzle brake is still in the box. When I was much younger, my folks owned an armored car company in the South Pacific and we had class III weapons: Wire stocked Paratrooper M2 carbines with that weird front pistol grip. They were widely available from the Phillipines back then. Never had any trouble with robberies. Those were the days. Island life, cool guns, and all the mil surp ammo you could ever want. What a long strange trip it's been.
