I have been wanting a good and reliable GBB SMG to use as a backup to my GBBR M14. The idea is to have everything be GBB. I've looked into pretty much all my options as far as reliability, parts availbility and price, and the guns fps rating to actually be used as it's design intended which is CQB. Seeing as I now have 2 KWA G18C's that are both functional, the Magpul FPG seems to be my best option. It's super compact when folded and pretty light weight which is a huge plus for me when lugging around my ~13lb M14 and ~25lbs worth of extra mags. Has anyone had anyexperience with these magpul FPG kits?
