That is one of the few truly good uses for aftermath stuff. If you want something to learn the ins and outs of airsoft maintenance, repair and upgrade it's ideal. you don't risk a good high grade gun to newbie mistakes. In the end you'll have a good high grade gun and a very good knowledge of the workings of airsoft. It will be more expensive then just getting the high grade gun to start with, but in this case the gun is beside the point, the knowledge is the point. I did the exact same thing with a Kraken awhile back. Broke a few parts, made a few mistakes but I learned. Now I'm working on building a AK hybrid. I have most of the exterior parts in G&P, once I get some more funds I'll start on the interior stuff.
