Well, if you feel you're limited by your gun perhaps you'll be interested in upgrading. I hope this helps.

http://www.evike.com/products/66423/ I love my FAMAS, but it's a nightmare to disassemble, has a shorter effective range than I'd like, and is currently not in working condition. I've always been a fan of the SCAR, and the Bren is pretty much a cool improvement on that concept (plus it's cheaper than the VFC SCAR's). That doesn't mean I'm getting rid of my FAMAS, though. I can't get rid of such a memorable AEG. For $150 it's served me well over the years, and I'll get it in working condition again.
