The Summit can be used as an arbor press with RCBS kit or it is easy to make your own to use it as an arbor press.

The summit as an arbor press is like using a 10ton hydraulic press to seat bullets. Itll seat bullets fairly well with threaded dies and its good for decapping but sizing or anything else its pretty much useless. I use mine mounted on a piece of heavy channel to seat bullets at the coffee table- but i wouldnt ever buy one again if this one broke tomorrow.
I have two. One with a short handle to seat bullets which gives ME the best feel for seating than anything else.
I mentioned using it as an arbor press because it can be. I happened to make mine from a ruined die and two valve shims from a VW. But I did it because I wanted to as I have no use for an arbor press.
I size with the long handle in the other with NO problems BUT I only size up to 308. Since it is a single action press (?) there is a bit of effort required.
Anything else goes in the A4 which I could probably mount a tire on a rim... lol
