I'd tend to agree with blue, mine is my first semi rifle...read through the threads here and went to town on mine. Never had a malfunction of any sort, shoots more or less where I point it...nothing at all complicated about tearing it apart, at least up to the trigger group which I have left alone - it's actually not half bad at all.
Spend a couple of hours in front of the TV running the mags in and out of it, and soon they will insert much more smoothly. Optionally, add sandpaper to smooth out the obvious wear marks on the mags, and a bit of oil.
I know mine's not as pimped as some - handguards, grip, some paint on the buttstock - but I'm happy with it.
