Hello Steve. It is good to see someone new doing integral features.
CNC certainly does level the playing field.
A couple of comments.

Since the parts are integral, there is no need for the associated bands with the sling swivel and front site. That being said, if it is a swap for the factory barrel and it fits the factory inletting it is understandable.
It wouldn't be difficult to strike that extra metal off for a restock or a custom build.

It looks like there is extra meat on the rear island and the front sight ramp which is great. Make sure the island is high enough to work with a stock with a higher comb. NECG express sights seem to be the go-to, but by the time you file them in the point of impact has gotten quite a bit lower. Easier to take metal off than to put it on.

Looking forward to seeing this progress.

Cheers,

Tom
