I am somewhat new to ARs and have a couple quick questions. I have a Colt 6520 Govt Carbine and am looking into putting on a new handguard. The main reason for this is to be able to put on a vertical foregrip with a light. I have been looking into the Midwest Industries Two piece Free Float and the two piece handguard. Would there be an advantage to going with one over the other. Any opinions and other options would be appreciated.
