Id think the VZ58 would require very little "investment" to surpass the M10x. Really the only thing the m10x has over the VZ is an integrated optic rail, railed forend, better trigger? And a flash hider. Is that worth the $700 difference between the VZ? Meanwhile the VZ offers:
Better accuracy
Iron sights
Better mags
Last round hold open
BHO button
Better balance
Lighter weight
More part support
And alot more modularity.
I agree with Bfiles point in that its great to have another rifle here in Canada. But like most have stated, its hard to justify the $2000 price considering what it brings to the table. Hence why it aint so popular.
Once you modernize a VZ to a comparable level as the M10x you are well beyond M10x cost.
Just between RS Regulate and Magpul your going to spend $700 mounting optics and adding a magpul stock.
Then upgrading the front you will spend another $300 on a heavy quad rail, because an Mlok one doesn't exist.
Then expect to easily spend another $100 on a good comp.
Looks like another $1100 on top of a rifle worth $1380. So you get close to the M10x for $2480.
You still dont have the ability to use folding BUIS, and both your weight and balance arguments will be ####ed with the weight of your clunky quadrail.
Not sure why you think the M10x isn't modular, mlok is the epitome of modular, what part support does the VZ have that the M10x doesn't?
VZ mags are needlessly bulky and dont fit most fitted pouches, and while the VZ does have a BHO, what good is it with out a bolt release?
The M10x trigger and safety is better, and the CH is ambi.
Needless to say, I think one is
far better off with the M10x if you want a modernized x39 rock and lock platform.
