I had one for a few years and sold it because it did not fit into my shooting, but it was fun, and my first centerfire rifle. It was heavy but no more than any other SMLE-type. I ran 308 and 7.62x51 ammo.
Reliable with a couple exceptions. The mag latch on mine was worn, and the mag hung a little low so it would not feed reliably unless the mag was supported. Yes, I disclosed this when I sold it. Spare mags were hard to get so I did not experiment but should have been an easy fix. Also, it grouped ok, until the front sight blade worked loose. Easy to fix, just annoying when I shoot someone else's target at the range. Oops.
Too me, it would not be worth $350 as a shooter but it certainly has novelty value.
