I don't own one, but like the idea of owning one. It's a neat, very niche, type of gun that would be more of a novelty than a practical rifle. Virtually all of my rifle training is combat centric, same with handguns. The pump action of the 7615 doesn't lend credence to a viable combat rifle as much as a semi auto. It'd be more difficult to operate from cover/ concealment, and from various shooting positions. I can utilize a semi auto with a single arm (simulated injury) by using a support, even if that support is my own knee in an awkward sitting position. The 7615 can do everything my AR can do. Once. Then it's time to rack the action and do it again.
As a hunting rifle, a 7615 with a 5 or 10 round mag would be a nice varmint rifle for yotes and such.
I tell myself I'd buy one if I ever saw one for a good price, but never actively look for one or research them enough to know what a good price might be.
Always been a little curious to know why they (Remington) never developed a 7415, semi auto version. Seems it would be on par with a Mini-14 as a viable alternative to AR ban states. The pump action is probably marginally better for hoplophobic juries, though, but that's hardly a good reason to consider when shopping for a home defense/ utility rifle.
If the charging handle for the AR is an issue, there are side charging handle uppers available, both reciprocating and non reciprocating versions, IIRC.
