Extractor cut for coned breached rifles with claw extractors. There are several differnet types of receivers that need extractor cuts such as this.
These include the M1917 Enfield, 1903 springfield, and the earlier or claw extractor M70 Winchester Rifles. This is just one way to make this cut.
The alternative with a mill is to use an end mill if you can tip the head, or a woodruff cutter.
A M1917 Receiver I did a few years back. I put a solid rail on this one to do something different. Still waiting for a barrel. This was a cut up M1917 Enfield that I reworked and made some of my own modifications to.
Most of the receiver has been trimmed down to cut as much weight as possible where not needed. Also A Timney trigger was added along with a Cock on Open conversion.
The front of the receiver ring has been squared off in a lathe and the bolt lugs have been lapped in place. You cannot square these in a lathe because they have canted lugs and are not square!
The trigger guard has been straightened along with a straightened bolt handle. The finish is a bead blasted and hot caustic blue finish.
You can do very similar conversions to British pattern 1914 receivers too! Very nice action and I can’t wait to get it all put together!
This is a few things I left out in the first video. This is a custom M1917 Enfield that has been fitted with a Hart barrel a Timney trigger, and a Richards Microfit stock.
