I haven't had a chance to shoot it yet, but hopefully laterthis week I'll get some time to get to the range, so I'm not sure on the cyclic rate or how well it'll actually work. Lakeside has plenty of experience with miniture versions of the Browning 1919 design though, so I'm fairly confident it run well (though having some experience with .22 MGs, I wouldn't be surprised if it needs a little tweaking or break-in period to get running good. FWIW, it cycled perfectly by hand).

I don't think the bolt has a set number of rounds before it'll need replacement. It seems very sturdy. The face is (obviously) steel so the body only provides support for the bolt face and the track for the cam pin in the topcover (which operates the beltfeed system). The back side of the bolt actually seems like a fairly low-stress part, just there to actuate the feed mechanisim.
