Chris,
I am using Corbon factory ammo. The subsonic uses a 220 grain bullet at 1040 fps (factory specs). My upper would not even work with the supersonic ammo straight from the factory. The overall fit and finish is fine, and I still think that for the money, it is worth the modifications necessary to make it work. It appears that it is manufactured with the standard .223 gas system/port location, etc.

I am still working the kinks out of mine to make it work.

I am in the process of trying to figure out how to fill the old gas port, and where to drill the new one.

From my research, any upper short of the SSK one will need these mods (Olympic being the only other one I could find, and they are currently out of stock)

Anyway, if you compare cost, the Model 1 is still going to come out ahead even after the modifications.
If you have the money, by all means buy the ssk. I did not, so I could not go that route.

And a little fiddling does not bother me to make it work. I like doing that sort of thing, and have a couple of friends who are gunsmiths who can help me with it.

I'll keep posting my progress on this forum.
