No i dont think so
for us the gun has to be rugged and robust. able to take punishment of the elements and its user should spend more time fighting the enemy rather than worrying for its service and jamming. there is always a trade off.. between over engineered and complicated machines that are high maintenance and expensive but offer benefits like accuracy and wide variety of use in different climates.
and then there are guns that are robust, require least amount of maintenance and dont jam and get the job done say at the expense of accuracy (AK47 family).
explain what was the marked differnce?
accuracy?
recoil?
jamming?
cleaning?
field stripping?
weight? size? assembly?
I have used CZ858 aka VZ58 around 6-7 times on the range. I own a similar weapon FA cugir Akm, the basic difference is milled reciever compared to stamped receiver. Although the system uses a short stroke and traverses less compared to AK47 stamped variant, recoil is still similar which IMO is attributed to entire gas pressure used for propelling the piston back. Although rearward force is higher, due to lower traverse of off center action, the muzzle climb is lower. The difference in recoil is negligible in both the system. Where VZ is better is accuracy, the VZ will hold a tighter group and have a lower muzzle climb.
As the last page has been in support of the vs, let me recommend a slight modification to regular AK. Adding a buffer tube to bolt which attaches to the back plate and installing a spring loaded buttstock (6 pos optional), will highly increase the effective accuracy of the AK. Another reason why most ak shooters cannot hold tight groups is because of non-existential cheek welds. Placing a cheek riser on an AK does improve consistence in shooting.
A lot of stamped AK have been constructed poorly and were meant for spray and pray, VZ 58 is a well made AK and does justice to the actual design. Does the milled receiver produce better results in operation? I dont know, but it surely does ensure the entire production run is of the same quality and the all parts are interchangeable.
Jamming? there isn't a gun that wont jam, VZ 58 will have the same probability of jamming as the one good quality stamped AK, but just like the AK it will be champion no hassle rifle compared to the M16's
Cleaning field stripping and assembly is similar but you will do need to train the troops about the short action, its pretty much like lego pieces, any one who knows gun, knows what to do.
Weight is more compared to a regular Ak but is lower than some AR 15 and FAL variants.
Size is same as regular AK.
Cost is more but the service live and ruggedness is increased due to the same milled receiver. It just might survive being crushed by Al zarrar!
