That's right you read it correctly, I am building a .45 acp Mauser.
I ordered the kit from Rhineland.
I had an ATI Mauser scout stock I had intended for another project but I decided to use it for this instead.
I have a ton of 45 brass and loaded ammo with only a Smith and Wesson 625 revolver to shoot it through, so why not a .45 carbine.
I am using a Spanish La Carona Mauser i got for $115. It had been radically bubbaized before I got it. The bore was rough and the stock had been hacked up really bad, however the action was nice and smooth and just needed to have all the crud cleaned out of it.
So I got the barrel off the action cleaned it out.
I Installed the Rhineland barrel and lock nut on the action following their instructions. I head spaced it with a dummy round. I will be going to a shop this weekend to double check the head space with a set of gauges just to be safe.
the two biggest challenges will be cutting out the bottom of the ATI stock for the magazine adapter and getting roll pins or some other type of pin to go through the stock to hold the magazine adapter in. Unless someone has the other version ATI stock that uses the metal trigger guard they are willing to trade for one with a molded trigger guard.
Here is where the project stands at the moment
So I think it is off to a good beginning.
