"shooter" Mausers
Tosi--I just browsed through my bookmarks of milsurp rifle sellers, and Auction Arms and Gunbroker. For the M-48, it would seem that the wholesale supply has dried up. AA and GB have M-48's at auction; they are individual sales. You pays your money and you takes your choice. Some would be in yr price range. FWIW, I've had good luck buying firearms from online auctions in the past. You do hear the occasional horror story, though. And what's available will vary day by day.
The following online sellers had Mausers in yr price range: (Be aware that shipping, and the fee for an FFL holder to receive it for you, will probably cost you extra.)
Centerfire Systems,
www.centerfiresystems.com has 24/47's for $149. They say the rifles are non-matching (bolt doesn't have same serial no. as receiver) but are XLNT condition. The 24/47 has a straight bolt.
Aim Surplus,
www.aimsurplus.com has RC K98's (RC=Russian Capture, prob. from the Battle of Stalingrad) for $219.95. None of the RC's have matching anything--the Russians disassembled them all and then reassembled rifles from the piles of parts. The Russians also left off the "capture screws," cleaning rods, and front sight hoods. Nice piece of history, though.
Samco Global,
www.samcoglobal.com has
several Mausers in yr price range.
J & G Sales,
www.jgsales.com has RC K98's and 24/47's in yr price range.
Classic Arms Inc,
www.classicarms.us has RC K98's they claim are in XLNT condition, at the top of yr price range.
The missing parts for the RC's are available, if they matter to you. None of the normally missing parts will keep you from shooting the rifle.
I'm sure there are other sources. Sorry I couldn't find a company selling M-48's--the advantages to those are that the bolt is already turned down, and it's a shorter rifle than the standard K98, therefore handier to the shooter. The disadvantages are: 1. The bolt is not turned down enough to just slap on a 'scope--you still must modify the bolt, or use a scout 'scope mount, and 2. The M-48 receiver is just a little shorter than a k-98's receiver, therefore, many of the retro parts made for K-98's won't fit an M-48.
IIWY, I wouldn't hesitate very long if I wanted a military Mauser. The sources of these seem to be running out, and as they do, the WWII-era milsurps will do nothing but go up in price.
