    Default VZ58 stroke long enough to run a belt fed?

    Hi guys,

    I have been reading the MG47 threads and the issue of piston stroke keeps coming up as important in making the top cover cycle. I have been considering a VZ58 as a base for an MG47 type build. The VZ58 uses a piston system like a FAL where the piston hits the bolt carrie and is not attached.

    Anyone know if this type of system could run a belt fed?

    Thanks,

    JJS

    Personally I don't think so. Its not that it is long enough, the question is does it generate enough force so as to overcome the inertia of the feed system. I'm guessing not since the impulse is measured to the VZ feed system. It moves the bolt carrier to overcome the spring pressure, unlock the bolt, depress the disconnector, slide a round from the magazine, and that's really all it does. Maybe? Maybe with a larger gas volume?

    Thanks for the response. There may be only one way to find out - try. I like that it is a compact platform and that I have a partial kit I got cheap.

    It might work, though the bolt might be a bit light, remember it has to pull the belt into the gun as well as all the other feeding things. There isn't a problem I could see with the short stroke piston design, though, the piston on a long stroke design adds much needed weight to the carrier... You'd probably have to open the gas port a bit too...
