Got the parts in hand for a M40 build.

The preferred builder is no longer building.

Who can do a proper build these days? Who can cut a legit clip slot/thumb relief spec build?
M40 or M40A1?
Both can be done at GAP, but need to specify you want the M40 clip slotting vs the M40A1 if that is what you are looking for. GAP can also do the US stamp and proper barrel markings if doing a M40 build.

GA does absolutely supreme work. Feels like I just checked it out of the armory. And Iactually carried an A1 in Iraq. In 2005. That is until another guys Mod 0s’ mildots melted while still on the wire. So he got my scope. Everyone else had an A3 with USO Mods or Mod 1s. One guy actually Used his own Leupold M1 Mk-4 in country. I got mine for just over 5Gs already put together, GA rifle, correct ring/mount, MST 100. All never fired........I’m just a lowly swine. Never went to school. But, now I have a few rifles from when I used to be dangerous. After my children, my M40A1 is my most valued possession. If I were homeless and needed to eat, I would not sell it.

During the last MST-100 cycle I believe when you called USO's business number more often than not Becky answered the phone. Check out the USO website and dial up their main line.

How important is it to get the correct serial number range on the receiver?
Thats your call.

Its just numbers, there is no manufacturing difference really.

You determine whether having a G Code (M40A3) would cause you the stress of not having an E Code, other or 6 Digit.

I have a PWS built gun but its a G prefix.

Im happy.

Any details on the beautiful lady?
Takeoff stock, hardware and bottom metal, CMP acquired Unertl, Hart M40 profile barrel, 2man rings and base, the action was one of the Remington M40 commemorative clip slotted actions, all in all really nice build by IBA in 2014-2015. Have the tenbraex polarizer and the kill flash was on the rifle in the pic. Hardest part was finding the Marbles brass cleaning rod and the armory fabricated issue spanner wrench. Was going to strip the paint off the stock, but its a piece of history with the layers of paint on there.

I had a rifle built by Mark Williams at Raven Rifles, @Raven 6

Though not an M40A1 it is M40/A1/A3/A5ish. Had it out yesterday at Sig Academy......

Mark has studied the USMC details and according to those that know those details a lot better than me he gets it right.

You will have to wait, especially you will be in line behind me as he has all the parts needed to build me an M40 right now, but it will be worth the wait.

I luv it, but that scope is cheating. :)
