hello and Question on rail

Hi,
I just wanted to say hello.
I am new.

I have a bushmaster XM15-E2S
I have always loved a bushmaster. I had 1 years ago 2003, never changed anything. I sold it. I bought another about 3 months ago, and now I am changing out a few things.

I am looking at 2 rail systems.
1 OMEGA 7.0
or the KAS M4 rail kit.

Originally I was looking at the DD EZ car 7, but it is a little wider than what I wanted. I think the DD Omega 7 is good, I was considering the KAS M4 rail kit, but I cannot find anything on how wide it is.
I was at the gun show 2 weeks ago and the width seemed good.
If I get the OMEGA, I am going to have to wait and try to find 1 used as dont want to shell out $250 for 1 thats brand new.
I saw some selling for $175 range, which is about what I want to spend.
Any thoughts on these 2?
Thanks
Chad

huh

buy once cry once, get what you want the price should not affect you that much, because if you get something you dont want you will regret it and sell it for a loss, and buy what you want paying extra.
