Default 308 Conversion questions

I am about to order a CMP Garand. My first. I think I would like to convert it to 308 as I have several other rifles in this caliber as well as dies and reloading materials. I have a TON of 308 ammo stored. Mostly 168 gr. But I have other bullets of all kinds and weights.
My first question. Should I just order a field grade and then have the rifle converted ? Or am I likely to be much happier with a Service Grade rifle wood parkerizing etc.. I enjoy saving money as much as anyone but the price difference is not my main issue. I assumed I would get a FG delivered sooner and the wood would likely be good with probably a shot out barrel?

Second question. Who should I have convert it ? I want a shooter.

Krieger or Criterion ?

I believe there is an option to have the CMP put a .308 barrel on before they send the rifle to you. I don't know all of the details on how that is coordinated in the ordering process but I believe basically what they do is fulfill your SG order and then send the rifle directly to custom shop to do the barrel swap, and then the rifle gets sent to you. This may take awhile with the current shop backlog. But may be an option if you want a .308 directly from CMP. Others with more knowledge and experience with the CMP may be able to better describe this option.

"I assumed I would get a FG delivered sooner and the wood would likely be good with probably a shot out barrel?"

That is way too big an assumption. Read the FG specs and assume the worse. If anything, the good wood assumption might be a bit too high an expectation. Count on receiver putting under the wood line. Service Grades are a much better bet but, I read they are no longer taking SG orders.

There are also CMP rifles already out there. Put a WTB ad on the forum for sale list describing what you want & if answered require photos and answers to questions such as pitting/corrosion/parts ID/bore condition/ME/TE etc. CMP sold some Field & SG “Specials” several years ago barreled w/new or refinished parts & 0 MEs & TEs. I bought one from a forum member that’s like new. (Not for sale)

Most people consider all 3 grades (Rack-Field-Service) to be shooters. Sure, MW/TE is a primary part of the grading process but they are all capable of shooting and grouping to a reasonable level.
So many people get focused on "the numbers" and forget to actually "Choot It" before replacing a barrel.
This forum is full of posts where high MW/TE numbers shoot great.
Here's my rack grade Garand, 1st shots after I got it; stripped, inspected and reassembled, after a few clips it tightened up well.

Some suggestions:
1. CMP has a backlog now, will be a few months until they are ack to the several week delivery.
2. The CMP custom shop ALWAYS has a backlog. The have a good reputation, and it is convenient.
3. Swapping a Garand to a .308 is easily done by other M-1 specialist gunsmiths, and will be quicker than CMP if that is important. Several have been suggested above, plenty to pick from. If recommended here on the forum then just pick one, they all will get that done to the same quality, including the CMP shop. Many will also sell you the barrel, same as CMP.
4. CMP's 3 grades also reflect the parts condition to some degree (not 100%), so consider that. Rack grade parts will generally be more worn than a service grade. You may want to just get the best chance of the best parts, and address the stock separately.
5. CMP new stocks sell here regularly, and you may get a valuable stock to trade/sell/

Unless you make every decision to spend the least $$$ you can't really go wrong. Buy a CMP rifle or one off the marketplace. Buy a barrel, find someone to swap it. That gunsmith can also gauge most parts and advise you if any are near end of life.

Shoot whatever you get first, you may find it shoots great and you then must buy another Garand for your project. Shoot that one too. See where I'm going?

Know that within a month of completing your project CMP will announce a batch of .308 specials for sale.
Keep us posted

It's really a moot point right now since field grade is the only in stock option. A special rack grade in 308 would be perfect if they bring them back.

All of the recent Field Grades I have seen looked a little beat. You will have to get the entire rifle re-parked, get new wood, have a gunsmith install a new .308 barrel and then begin shooting. Try the Want To Buy ads. Good luck.

A rack special is what, $650?
$300 for barrel + swap.
Reparked, new stock; if the goal is a shooter that is a quick and efficient way for a great shooter.

Built a TIPO-2 rifle in 7.62x51 NATO. SARCO I think still has barrels. I do not know about the shorter op rods, though.

Here is, I think your best sequence of events:

Step 1: Buy a M1 in your price range on the Forum here.

Step 2: Send to Tim Shufflin (Google) in Michigan for barrel installation and if necessary reparkarization of metal on rifle, your call on that.
He does superior work.
Current turn around is 90 days (I checked).

Then you have an:

M1 in 308, looking brand new (metal) and you can consider changing stock if needed depending on what you originally purchased.

His prices are very reasonable, see his web site.

All the best.



If the take off barrel is good , you can sell it on the Forum to defray some of your costs.
