I finally bit the bullet(BB?) and ordered this as my first GBBR. I've put around 300 rounds through it so far, and I'm quite impressed. The quality of the components is top-notch. There is very little rattle in this gun, most of which comes from the magazine and stock. It feels solid, heavy, and tough, which is what a good airsoft rifle should feel like. It's easy to maintain, easy to upgrade, and if you have a shorter inner barrel kicking around, you can take the 4 outer barrel extension off, and make a 10 CQB rifle in about 5-10 minutes(the tools needed are included, which is a bonus!). The mag also holds a fair amount of gas, I can dump a full magazine, even in sub-zero temperatures. The paint finish in some places was a bit weak, and could even be rubbed off, but most people don't usually baby something like this anyway, so it shouldn't be a big deal. However, a buyer may want to invest in some RA-Tech locking receiver pins, as the factory ones tend to try and sneak out once in a while. All in all, it's not a bad GBBR choice, and with some RA-Tech internals, it would be a go-to choice for anyone that wants something a little more fun to shoot than an AEG!
