My G&P has an S-System. I got it because it was on sale and looked pretty sweet. But, after playing with the gun a few times, I notice that it is bulky and very front heavy. Are there any advantages to an S-System? I'm not planning on putting anything on the gun as far as flashlights or grips, so should I just remove the S-System and go for Magpul Handguards? Also, the S-System doesn't have a Delta Ring or the front piece to put in a handguard...is that a simple fix by just buying the parts?
