I'm sure this has been covered before, I did a search and didn't really come up with what I'm looking for. I'm wanting to upgrade my 7.62x39 ar with a new Handguard and optic. I have the basic plastic one now and would like to get a free float system. I'm not looking to spend a whole lot but $150 or so would be ideal. What do you guys recommend? Also any brands to stay away from? I've been looking at the diamondhead vrs series and also the ones Anderson manufacturing makes, which are all currently out of stock. Any help is appreciated. Thanks
