I have to be honest and say they look very similar to my eye. I have handled an Omega X and it seemed extremely light.

The other choice I am stuck on is whether to order with the fixed front sight or go with the low profile gas block and a flip up front sight. I plan on buying a Magpul rear flip up for sure and will eventually get an optic of some type. When I asked about running a fixed fsp with an optic at the local store, the gentleman there had the opinion that it cluttered the view in a SD situation.

Being this is my first rifle, it's tough to know what I want until I have bought and used it for a while and figure out my needs. Apart from range use and (hopefully not) SD/HD, there is a chance I might take some classes at a later date.

Thanks for any input you can provide, and in general as this forum is a great resource for a new guy like me.

Cheers,
Matt
The Lite Rail is slightly smaller in diameter than the Omega rails. It's thinner side to side making the shape more oval.

Both the Omega and Omega X have built in QD sling mounts on the receiver side of the rail. They are also removable for easier cleaning under the rails, if it needs to be done.

The difference between the Omega and Omega X is that the Omega is a drop in free float rail. It uses the standard barrel nut and delta ring assembly. The Omega X uses its own barrel nut and requires removing the FSB for installation.
