"I received the A&K LR/GR-300 for Christmas, for I asked for it. It is a fantastic AEG. The motor is quite loud, like most other A&Ks, but with some tuning, my rifle is shooting at a great RPM. (I don't want to give an inaccurate guess.) For a little under $200, you'll be getting yourself a fantastic AEG. My pros and cons include:

⋅fully metal
⋅folding stock (good for storage)
⋅totally customizable and upgradeable

⋅low rail space
⋅front wired (personal opinion)
⋅needed some tuning
