I just bought a RRA m4 entry and the handguards have about a 1/16" of rotational play. I was wondering if there is way to tighten them? A couple of my friends have AR's Bushmaster's and Colt's and they don't have this problem. Is there any way to fix this and is it normal?

I want to put the m4 handguards on my ar....
was it a pain in the ass to get the old ones off.. do you need like a special tool to get them off???

The barrel nut teeth fit in a slot in the handguard.  Inside the slot are a couple dimples that are supposed to fit between the teeth and prevent rotation.  

Some put a small dab of silicon caulk or gasket sealer in the slot.



Handguards can be removed by hand.  I find it easier to separate the upper and lower.  I put the upper reciever on my desk with the barrel up and push down on the delta ring.  The first time will be awkward.

thanks
