[AR-dawg]

Let me start by saying the AR is completely new to me. I got a new Bushmaster 6.8 (BCWA3F 16M468) about a month ago and now I'm looking to upgrade to a new rail system. My plans are to add a vertical grip (probably Larue FUG) and light (probably Surefire) in the new future. I'm looking for recommendations and advice. I'd like something that doesn't require me to do a lot of specialty work - I'm handy with tools, but not a professional. I was looking at the Daniel Defense Omega Rail 7, as it appears to be one of the best and easiest to install. What do others think?

What are the requirements if I go to a longer rail? I've read stuff about a low profile gas block, but I'm uncertain as to what that relates to.

Again, the AR is new to me so please forgive the newbie question. I do appreciate any help you can offer.

The Omega Rail is definitely the easiest way to Free-Float your upper. Another easy one is the Vltor CSV Handguard. The third easiest is the Troy/MI/Samson. Those you have to remove the delta ring, which is easy to do. Here is a video series on how to cut off the Delta ring and install the Samson Rail, which also applies to the Troy and MI. Samson also makes some rails that will extend over the Front sight base such as the Star CX and the Star CX EBR, which looks like this:

If you want the rail to completely cover the gas block, you can get a low-profile gas block that looks like this:

or you can actually get your front sight base cut/grinded down so it will fit under the handguards.

This is a picture of the handguards that go over the gas block:
