Is Saiga really like an AK . . . more or less so than a Norinco SKS Sport that takes ak mags or a MAK-90? Also how would these stack up against a Ruger Mini on the battlefield?
A Saiga, as noted, IS a Kalashnikov. Just has the trigger group moved back a bit to work with a conventional butt stock, different hand guards, and needs a slightly different magazine. All of these things are cosmetic and can be changed easily to make it the same gun as any other SEMI-AUTO version of an AKM.
A MAK-90 is a Kalashnikov, too. Just made in China.
An SKS is a totally different rifle. Just as reliable as an AK, but substantively different.
How would these stack up against a Mini-14 on the battelfield? Hard to say. All can have problems. All do have reputations for very good reliability. None have reputations for exellent accuracy.
What criteria will you use to evaluate them? How to they stand up on the battlefield? Well, if you stack them just right, I'd think they'd stand up for decades, at least -- if the wind don't knock 'em over...!
Seriously -- what's your measurement?
Is the Mini just loosely based on the m-14 but is really a hunting gun?
The Mini is loosely based on the APPEARANCE of the M-14. It is a semi-auto rifle in .223. There are better hunting guns. The caliber(s) available are somewhat limited. There are worse hunting guns, too. Same could be said about an M-14. What are your criteria? Accuracy? Ease of putting optics on it? Rate of fire? Mean rounds between failures?
Is a tactical Remington 700 just as formidable a battle firearm as the Ruger Mini then?
What is a "tactical" M700, to you? A M700 is a VERY formidable rifle, but it doesn't have the characteristic features of a main battle rifle or infantry rifle as adopted by modern militaries. As a highly accurate, long-range, anti-personnel rifle, they do get quite a bit of use by our armed forces. But not as a "battle rifle."
A Ruger Mini-14 shares a few features of many common infantry rifles/carbines. But, it isn't fielded by any military forces (that I know of) so it isn't much of a "battle rifle" either.
