Ejector Screw

The following is from British Manual:

Précis No. SA/Rifles/2 (Dated March 1960)

EXTRACTION AND EJECTION

16. On raising the bolt lever, the bolt is rotated to the left, forcing the stud of the cocking piece from the long to the short cam groove and withdrawing the striker about 1/8 in. At the same time, the lug of the bolt moving in the inclined slot of the body causes the bolt to be withdrawn about 1/8 in, the claw of the extractor gripping the rim of the fired cartridge case effects primary extraction or the first loosening of the case in the chamber.

17. As the bolt is drawn to the rear, the extractor withdraws the cartridge case from the chamber and carries it to the rear. The case is ejected from the body of the rifle by its rim bearing against the ejector groove on the left side of the body. When unloading a live cartridge, because of its length, ejection is affected by the rim of the case striking the ejector screw.

18. As the bolt reaches its rearmost position, the compressed magazine spring positions the next cartridge ready to engage the bolt face on the next forward movement of the bolt.

The photo below is from the 1991 Canadian manual.

I replace the ejector spring on all my shooter Enfield’s, the spring spends its entire life under load with the bolt closed. Weak ejection and bolt jump can be caused by a weak extractor spring, also when you pull the trigger the extractor spring is holding the bolt in position or pushing the bolt locking lugs into the receiver lug recesses.

A strong extractor spring is your best friend, a weak spring accelerates wear between the bolt body and bolt head.

I have a problem... I too thought this hole was just a mounting point and thought nothing of it. My action came without this screw and the previous owner seems to have ruined some of the threads... What to do now?
Retap the threads and clean them up, below is where to get the British type taps and dies.

Screw, ejector = 3BA (Number three BA (British Association) Thread type)

Thanks for your help in a few of my post Edward. I ordered the 3BA Tap and two of the British Fasteners 3BA Cheesehead screws in 1/2 inch to cut down to size. I already eBayed an original ejector screw to use but got spares in case I have problems. I also ordered new Extractor and Firing Pin springs from Midway and a bolt tool (from gunbroker) to make this a completely refurbished gun. Thanks Again

Just remember you can always trust me I was in the Air Force, just watch out for those low life Marines in our forum they will steal you blind and blame it on the Navy.
