Yay, a pointless quote with nothing attached.
If you're paying $900 for a stock WA M4, you're getting ripped. You're paying almost a grand for a plastic bodied gas M4, which might not work that well in a cold environment, with mags that cost anywhere from $50-150 apiece.
You, at 14, getting a WA GBBR for playing in the PNW, is either dumb or lol. Coming from me, that probably sounds weird, but just get a really nice reliable AEG and plenty of mags that cost $7 apiece and batteries that cost $20 apiece. And oh look, money to spare on a gun that will actually work all year 'round.
*hear-say begins*
From what I've *heard*, the WA M4 itself sucks anyway. Not the system, but the gun. I haven't ever actually used one, so whateva.
