The only difference is at the back end.
The full auto carrier hasn’t been cut away, both lightening the SA carrier and removing the part that trips the auto sear.

Both work fine.
Depending upon what type of gun I’m building will depend on which carrier I use. It’s a balance thing.

Go with whichever is cheaper.
