Ya know, I brought this up a few years ago.
I really wish Ultimak would make a gastube replacement with the rail milled in like they do for the other rifles.
I actually contacted them, a few years ago, and they seemed to think there was no market for it. I have recently come back to the gun world and as I look at all the posts and pics of SKS rifles I still think there would be a market for this. I think it would make the SKS a very viable pig gun. I mean, think about it. You wouldn't have to bubba up the gun and you could get a micro-dot with a co-witness and maybe even hang a light off the rail and you'd be set.
I know that Tapco makes one, but I don't like the plastic that is on the rail and the fact it will not co-witness. Batteries fail and I just always want the ability to use the iron sights without having to dismantle the red-dot when it does.
I wonder if we got up a petition and showed them the interest was worth their investment they would change their minds.
Just my 2cents worth.
