Bolt is serialized to the action, and has good headspace.' This barreled action appears to have been rebarrelled since the barrel does not have the typical Remington proof marks/stamps on the left side of the barrel, and has a recessed crown. Short action Remington M700, clip slotted and US marked.
This barreled action is serial number 6257239, and may have been an USAF rifle. ' M40 Sniper Rifle Barreled Action (serial #) 6257239 Information is lacking re the mysterious USAF M40 rifles, but I will note that CMP auctioned off one of these barreled receivers in 2015 (for big $$), that may have been transferred to them from the Air Force: ' I have 2 Rem 700 receivers the one I'm going to build on first is ser # 6,243,9xx does this number fall into the correct range for the m40'.Īs others have noted, that is not in the serial number range for USMC M40s, but apparently your serial # of 6.24M is kind-of close to some M40s reportedly used by the US Air Force (and for R&D purposes).
