FWIW, if you haven't inletted one of these before, be sure you have clearance aft of the rear tang.

I was surprised, it was clearance for the tang as well.

I got one of the last ones out of e-store a week or two ago as well. I really wish the CMP would continue selling these out of e-store.

My understanding is there were too many returns. If that's the truth, what a shame. A "vocal" inept minority once again directs the way we all go. Seems to be worse than a plague in this country.

Yeah, I bought 2 stocks a couple years ago and had to do a little trimming, nothing that a chisel or a dremel could not handle, this one, no trimming at all, just BLO. All my 03's have CMP stocks now and all have a relief cut at the tang so I am set.

Yep, they drop right in, have plenty of clearance at the tang, and a 1/4 to 1/2 inch gap between the forend tip and the barrel. Sure looks good.

Unfortunately, the only way to get decent accuracy (less than 2 MOA) is to spend hours re-inletting the action or put a washer under the tang, which has been ruled as illegal for CMP match use.

Many folks with a lot of experience with these rifles have tried multiple CMP stocks trying to get to fit like a USGI stock. It isn't happening.

And absolutely no reason to be calling people "inept". Chances are they know quite a bit more than you do about what it takes to make a 1903 / A3 shoot.

Chances not.

Sorry you took offense.

I'm on #3 CMP A3 Stock in the past few years. We can trade scores/standings if you want to go there.

On my 3rd. After a lot of work, the first 2, a 1903 and a 1903A3, both have about 6-9# pressure forend-to-barrel.

What kind of pressure did you get with your "drop-in" installation?

I am the one who said "drop in", have not shot it yet, so I don't if it will need adjustment or if it is good to go. Sorry you had probs with yours, could be I got a 1 in a 1000

Also, if you have a newer stock the lower barrel channel was routed out differently, so there is less force bearing on the barrel.

I fit the first, a 1903A3 stock and had the gap at the forend issue. Later, I bought one for a 1932 1903 and had a HS44 barrel installed. Same issue. Contacted the CMP and they told me this was normal with those stocks and to shoot it, tightening the stock screws every 5 shots until everything seated correctly. That didn't work. Researching stock fit, the GI manual states there should be about 5# pressure on the forend tip. Match rifles are fit for more pressure, up to 10# for best accuracy.

Checking with some experienced 1903 gunsmiths, several have had a lot of the same problems with these stocks and will no longer take on jobs fitting them because most folks buying a drop-in stock, as these are advertised, don't want to spend hundreds of dollar getting them to fit correctly.

I did accuracy testing using handloads using the Nosler 168 bullet with 48 gr of 4064. The 1903A3/NOS HS 44 2 groove barrel, with the stock as received, handguard clamping the barrel to the forend, accuracy ran in the 3-4MOA range. Installing a washer under the tang, as my Greek 1903 was received, to achieve positive forend pressure, groups shrank to the 2-3 MOA range. Installing a thicker washer which gave me about 8# pressure, the rifle delivers consistent 1.5MOA groups.

I then did the same to the 1903 and that rifle, with a NOS 44 HS 4 groove barrel, dialed right in with about 6# pressure.

The A3 took a lot of work to get it bedded so the tang washer is no longer needed. Now it's legal for CMP matches. The 1903 I'm leaving as-is as it's set up for CBA shooting with a Lyman 48S and Lyman 17A up front.
