CMP delivery No. 2

This one came in new cmp wood. All the parts seem to be Springfield. The bolt drawing number, heat lot, and matching wear of the original finish leaves a strong chance it was original, or got lucky during arsenal rebuild.

After degreasing the barrel, I discovered that this rifle had seen some wet.
Attachment 115275
Looks to me like light pitting under the parkerization - possibly refinished and rebuilt after service in the Pacific?
While the muzzle and throat gauge much better than the first rifle, it's interior confirms it was neglected, or saw service in a very wet humid environment (I think most of these all came back from the Philippines lend/lease, so that could be it too). Here is the before and after cleaning of the bore.
crown, 12inches, 3inches from chamber, freebore, shoulder

Frosty but no cleaning rod damage at the crown like the last one.
Cleaning revealed the true condition.

The first pic is at 12inches, and is the average of most of the bore except for a couple "spots" of deep pitting. The second pic is a ring of previous corrosion about 3 inches from the chamber.

Maybe one of the Phillipine returns? Wouldn't CMP have corrected that rust issue? Especially on a service grade?

Some definite pits there. Might just shoot great though.

It's hard to see in the picture, but the "spots" aren't active rust. Its surface etching or small pits. I had the flash on to make sure the spots showed up well. I think whatever rust was there was corrected during one of the arsenal refurbishments, where it was re-parkerized.

Well, second rifle almost done and put back together without incident. Almost too good to be true...and it was up until the ejector wouldn't go in. The spring has a kink in it, and wouldn't fully depress - the edge of the ejector catches on the edge of the hole because the spring is kinked. I tried to work with it, and that's when the ejector and spring slipped and went flying across the shop. Found the spring. Ejector is unaccounted for. I guess it's a good excuse to clean the shop.

Thank you. It would have surprised me greatly if CMP had sent it out that way.

out of curiosity I did some digging on putting on a new barrel just in case this one doesn't shoot well. Criterions are backordered. Then I though...hey what about adding a mount? griffin and howe are still in business. what would that take?
late April 2017 cmp forum post...

...An alternate option is to ship your M1C barreled receiver to Griffin & Howe (as I did) in Andover NJ. They will furnish their mount and 1" rings for $375 parts + $46 labor to fit (1/2 hour) + return shipping + $9.50 insurance, a total of less than $500. My tab was $482...

hmmm. that sounds doable and in my ballpark price range.
Then I went to http://secure.griffinhowe.com/mountsandpads.cfm to check...
$775 parts + $277.50 installation.
Has inflation been that bad or am I missing something? Were they possibly using old stock in 2017, and the huge price hike is due to new manufacturing? But that doesn't account for the huuuge increase in labor. you'd think it takes the same to install one as it did in 2017.

new ejector and spring came in today. I tore apart (cleaned) the shop USMC field day style and couldn't find the original. probably slipped into a crack, never to be seen again.
Note to self...put the cleaning tool in the vise, and press the ejector in from underneath the bolt. All came together on the first try, and I disassembled and reassembled 5 more times just to make sure I wasn't lucky. no $50 tool needed.
it's much easier than reassembling the extractor onto a No. 4 bolt head, but that's a separate discussion...merica.
If it don't shoot well, I may go with the idea above, fit a new barrel myself and shoot it while I save up for the inflated griffin-howe price. even m1{c,d} clones are going for more than the total I would have in this rifle when it's done.
