First let me say I’ve had 3 different RAS’s and have no complaints on them, and I currently have one on my LMT. I’m now looking to add a rail to my 6920. I will also add that I have several extra KAC rail covers and can get a RAS cheaper than the Omega. If I get a RAS, along with the extra rail covers I already have, I shouldn’t need to add anything else to the rail. So it seems the RAS has a slight lead already.
With that being said, I’ve heard a lot of good things about the Omega but I have zero experience with them. I do have a couple of questions about the Omega’s,
Will/can the Omega loosen the barrel nut? I know it can’t back out due to the gas tube, I was just wondering if this is possible.
Will/can the set screws back out, even with blue loctite?
For those that have an Omega what more can you tell me, especially anyone who has ran them hard.
I say, if you could get the RAS for less, I would just go with that. I have one myself, and they work as they should.
I can’t remember exactly, but I think the Omegas are free floating right?
I don’t personally own an Omega, but hopefully these set of excellent pictures of assembly process might help answer your question.
Thanks for the link, I had actually viewed that link before but had lost it. I’ve got it saved now. Yes the Omega free floats off of the barrel nut. I don’t know anyone who has one or ran one hard. I’m not sure how great it’s benefits are over the KAC to warrant a slightly higer price.
I’ve got a RAS and an Omega both of which I have used “hard” over several years. If I were paying for another rail between the two my money would go to the Omega. The RAS I have has become a little use after a few years and several thousand rounds, while the Omega has not budged. I have even moved the Omega to different uppers, and have never had any of the set screws back out under use. As with anything on a rifle with threads, blue Loctite is your friend.
However, if you have access to a RAS at a good price that may decide your choice. The Free float is an advantage but whether or not you need it is up to you.
Personally, I would go with either the RAS or the Omega X. I don’t like the rail extension on the standard Omega that bridges the gap between the upper and the rail.
The Omega X is harder to install the first time, but things are moving towards the more monolithic streamlined look of rails without a Delta ring. You can’t go wrong with any of the three, imo.
