JG GBBR???

Well, my B-day is coming up, and I've been wanting a GBBR for a while. The instintaneaos trigger responce and realistic action and bolt has always been a turn on to me. So im asking, should i buy the JG GBB? I've heard already thats it better than the AGM, and for $80 you cant really beat that...Im not asking for suggestions, im asking what would i need to replace soon enough? I've been looking at RA-tech's Products. And why do some GBBR actaully have Bolts while others seem to have just a little metal sheet that goes back and forth on what looks like a Piston assembly?

Thanks,
Ben

Before buying ANY new gun, let alone some obscure JG, you should follow the following steps;
1. Contact someone who owns it.
2. Find and read THREE reliable text reviews.
3. Watch THREE different videos. Can-shooting doesn't count, it has to be a detailed run-down.

My personal two cents:
At this point, GBBR's are still on the fence of skirmishability. They still have ridiculously high stock velocities, low reliability, and very little info on them. Spare parts and support are still scarce, too. If you don't already have a solid, reliable "premium" gun, don't get a GBBR. If you don't, it's a bad idea to skip from an MPEG to a GBBR. Even worse is to get a GBBR as your first gun. And the ULTIMATE offense would be to not have an Avtomat Kalashnikova

i told him that he should read some reviews but no.. lol
