Finally gonna purchase my first "assault rifle" and I am dead split on either the Arsenal SGL-31 or the Colt LE6920. I can get both for pretty much the same price, but whichever one I go with I want to put rails, optics, etc. on it. I know the Colt will be more precise and accurate probably but I'm not looking for a sniper rifle, and I feel like customizing it will be quite a bit more than the Arsenal to get it how I want it. That being said, is the Colt just a flat out better rifle or will the Arsenal serve just as well as a defensive weapon? Any input is greatly appreciated.
