to begin with, the m48/m48a is a fine gun. however, what myself and other milsurp enthusiasts object to is how mitchells tries to market them as. i'm sure you've seen the ads in various gunrags, for a 'WWII-era unissued German K98 M48'.
its misleading, as many people (do a search for mitchells here, you'll see that theres a LOT of other people who are lured in by mitchells advertising) assume its a rifle that *would* have been issued to an axis soldier.
now, others will correct me, but i was under the impression that all the mitchells m48s were made after the war?
peruse your local gunshops and pawnshops, you just might find an actual pre-WWII mauser in good condition. there are a couple of sources for them, the yugoslavians captured a bunch of k98s, wiped as much identifying marks as they could from the action, and put them in storage. these typically have etched on them 'M98' or 'Mod 98'. they are very nice rifles.
the others come from russia, who recently started selling off their supplies, and now theres a good amount of russian capture mausers available. they seem to have had more wear/tear, then again, they were surrendered by germans on the eastern front.
both the russians and yugos rearsenaled everything, and after they put them all back together, etched matching serial numbers on them. the russians did a slightly poorer job at this than the yugos, in my opinion.
personally, i like the idea of the history behind a german rifle captured by allied forces. theres usually a lot more personality in such a rifle, than a m48a that has gone straight from the factory to storage.
also, dimension-wise, the m48's were not exactly the same as k98s were. you'd almost have to hold them both to see what i mean.
