Question on AR-15 hand guard

[mallarddrake]

I just purchased a 300 black out 16 inch upper and it has a stock looking military 7 inch hand guard with a low profile gas block with rail and was wanting to replace it with a free float hand guar. question is do I have to use a 7 inch or do the ten inch fit over the gas block and what is the best hand guards to use Thanks for the help

As long as the gas black is a low profile gas black, you shouldn't have a problem with as long a hand guard as you want. As far as what hand guard to use, are you wanting lightweight? Or something with rails to hang lots of stuff on? Price range?

If the gas block has a rail on it the it most likely isn't low profile enough to have a free float hand guard put over it.

Would like to have top rail and maybe just a couple two inch bolt on for a bipod and sling Trying to upload pic but don't think it's working

Ok sorry it worked I may be a computer guru

Your going to need a low profile gas block if you want to go longer than carbine length. I'd recommend getting a Troy, they seem to fit inside of everything. As far as rails go, lots of different options. Troy also makes several rails that are pretty user friendly to install because they mount off of your existing barrel nut and do not require specialty tools.
