I’d say go for it, you’re not going to hurt your bike unless your bombing off huge drops onto flat ground. Really the only thing you really need to worry about is your wheels and if they can stand up to the beating you’re putting them through. It’s not like riding trails you’re going to crack your frame in half cause you don’t have a rear suspension.
My hardtail has gone off three foot drops and rough trail and rocks and I’ve never had any issues. Bear in mind it would be comfortable and easier to tolorate on FS but your not gonna wreck a HT riding it hard, unless you got it from Wal-Mart 😼
