I'm thinking about buying a Knights RAS for my M4. My question is: How can you make the bottom rail not move? I handled one at the local gun shop and like it very much except the bottom rail can move around.

you really can't keep it from moving. but it's not a big deal. it will wiggle a little. i am looking to sell my RAS and buy a Free float tube. want mine?

I tightened mine up a little with a light tap on the metal handguard retaining ring with a brass punch. Its held so far with some decent verticle foregrip torquing. Another option would be to buy the SAS lower rail that has the locking tab and screw.
