Good morning - hands down, this is the most informative source I've found on the Mauser M-66 SP. Prior to my simple NOOB question, I wanted to thank you all for your content. Difficult to source information for this rare model (360-500, in total).
Add me in as a grateful owner of this iconic former Italian Carabinieri rifle, from Atlantic Firearms, 4 years ago. It was in excellent shape, upon delivery, and only had a chance to oil it & store before I went overseas. Arrived home, and went to finally examine it closely. This was prior to finding this thread.
I easily removed the sliding bolt mechanism & it was well preserved (forgive me as I lack the proper technical terms).
I tried to reassemble it, unsuccesfully. I read the Mauser manual online and in this thread above. Figure #5 show armorer removing firing pin. As for assembly, it states to reverse the steps. That's it. I had planned to go to the range and waiting on someone kind enough to walk me through how to re-install the bolt carrier slide package. Any assistance would be greatly appreciated. Here are a couple photos, with bolt removed.
I am not sure if have to press in the firing pin (remain alert to spring tension) as I rotate the safety at rear, so it rotates the small fin pointing down. Fin is obviously blocking carrier from sliding forward. Yes, go ahead & say it, lol. I'm the numbskull that is dumbing down the gene pool. I Boy Scout promise I will educate myself further, take an armorer, find a local mentor and purchase proper tools. I need some help right now.
*Btw, I noticed the serial numbers were only 5 numbers away from the gentleman here that picked his up from the same source. I'm honored to be a student of this forum. Thank you.
