    Default M1917 extractors

    image.jpgimage.jpgimage.jpgimage.jpgimage.jpg

    Here's some M1917 parts that have some obvious differences that could have caused interchangeability issues.

    The M1917 extractor on the left is a CV extractor. It is without a gas hole, is in unused condition and works very smoothly to extract a spent case in all modes.

    The one in the center is a Winchester extractor with a gas hole drilled near the claw. The claw is slightly worn on the left side. It still works well to extract the spent case from the receiver if the cartridge is loaded from the magazine but the bolt requires a greater amount of force to close on a cartridge that's loaded directly into the receiver. The difference in the radius that's cut into the leading edge is probably the cause.

    The extractor on the right fits a M1917 bolt but the claw is different and it won't close on a 30-06 cartridge. Does anyone recognize it? Maybe a P14?

    Yep. For the Brit 303 "rimless" cartridge.

    Thanks, i thought so. Are P-14 bolts interchangeable with M1917 bolts?

    Yes...........and no. Yes, it will fit into the receiver, BUT the angles on the bolt faces are different where they meet the face of the barrel. The cutout for the extractor (on the face of the barrel) is also different.

    I would say NO unless you are a gunsmith who has worked on these conversions. The compatibility of the M1917 bolts are OK. There was no compatibility between the three manufacturers of the P14 rifles on the bolts. Additionally the P14s were made in two different MKs, MKI and MKI* which involved two different bolts and barrels, so you are contending with 6 different P14 bolts that may not fit.

    Yikes. That means it would take some deep knowledge of the bolt variations in order to recognize and buy a replacement bolt for a P-14 and a Model 1917.

    Merc-- The M1917 bolt should be no problem as the US Army Ordnance insisted on compatibility. The P14 is a totally different animal. The Winchester P14 is notorious for being not compatible with anything. In any rebuilds stick with P14 parts and manufacturer's code. Each part of the P14 is marked with a "W" , "R" and "E". In the past two years I have rebuilt 4 P14 rifle projects where an individual attempted to just swap out P14 parts with M1917 parts and guess what it does not work.

    How do you identify a P14 bolt vs a Model 1917 bolt?

    Merc--

    The quickiest way is to check and see if the serial number was stamped on the bolt handle. The Winchesters were stamped on the top of the handle and Remington and Eddystone were stamped on the bottom. That's not say that the serial number has been removed by grinding which I have seen. As I stated before the P14 was manufactured with two different types of bolts, the MKI and MKI*. The main difference is a larger locking lug on the MKI*. The MKI* will not fit into the MKI rifles but the MKI will fit into the MKI* rifles. The MKI* can be identified with a * stamped onto the bolt handle.

    Below is an illustration of the differences between the M1917 bolt and P14 bolt
