So I took my brand new baby to the range today (finally) to get her all sighted in. Well now...with or without the magazine, each and every round failed to properly extract. The casing was pulled out of the bore and then just "dropped" in the chamber. When I tried using the magazine (have 2, tried both, same effect) the empty casing just sat there on top of the next round.

I am a greenhorn with firearms in general and completely ignorant of Enfield operating principles. I hope I'm doing something dumb and it's not a problem with the rifle.

Suggestions? Advice? :confused:

The ejector is a spring loaded plunger on the bolt face. If you remove the bolt and push on it, is it functioning in and out and can you feel spring pressure?
I dry cycled some rounds though an AIA at the range and the rounds flung out very smartly, certainly far better than on a DCRA 7.62 conversion.
 
Take the bolthead off and make sure that the ejector plunger is completely clean. The preserving oil may be gunking it up a bit, just blast it with some brake cleaner and work it back and forth to make sure it moves freely. Lightly oil it the bolthead afterwards to prevent rust. It should eject casings smartly no matter how slow the bolt is worked. As a side note, The bolthead on the AIA is a different setup compared to the original enfield and is more akin to a Rem 700 pushfeed.
 
I pushed on the ejector spring and it's there, it works...it's just not ejecting rounds. I'll take it apart and try cleaning as suggested, and report back. Thanks guys.
 
I CLP'd the crap out of the bolt head and extractor plunger and it's still not working. It looks like the front end of the casing is catching on the bolt head guide near the front of the ejection port. Could this be an issue because I was using 180 grain rounds? Could the casings be longer than normal and catching maybe? I bought em because they were cheaper than others in the store (Remington Core Lokt something-or-other).
 
If you cannot get it to work without modifying the bolt head, get a hold of Marstar and take advantage of their warranty ASAP, the rifle will be covered under their "ironclad warranty". If you modify anything though you will likely be out of luck.
 
Probably just crud as the guys have told you. But Marstar will fix it for you, and the rifle is worth it, mine shoots really well.
 
If you have anything capable of recording video to your computer, video it and put it on youtube. If it's a user or easily fixed problem, we'll have a solution. If it's a missing or broken part, it'll be identified and you can send it back to marstar.
 
Here's a couple of vids (sorry, bad lighting):

Hrmm, the lighting in those vids is brutal...I may have to redo that tomorrow so that you guys can actually see something.

And thanks for the troubleshooting help guys!
 
You mentioned using a specific type of ammo...are you able to lay your hands on some more typical .308 ammo?
It might be an ammo specific issue. My guess...the bullet is a bit longer than normal and it's buggering up the extraction/ejection geometry.

As long as the extractor spring is strong and the extractor is strongly bearing on the case rim, and the ejector spring is working, the rifle should be working fine.
 
Videos didn't help too much due to the lighting, but pics show a bit. You said that you cleaned the ejector, but have you checked that the extractor is holding the casing against the bolt face properly? Why kind of spring pressure is there on your ejector plunger(can you push it down with your finger without saying ow or does it feel like 20lbs of resistance?).

One other thing to try, just because I noticed and it plagued me on my m14..... move that front ring further ahead so that the huge frikken bolt is not over the ejection port, brass may be bouncing off on it back into the action. I had brass bouncing off the scope turret on my m14, took forever to diagnose. Hopefully it is that simple.

Well the extractor is pretty easy to move with my finger. The ejector is quite stiff...should have more than enough oomph to launch a little piece of brass.

The head of the casing is not held square against the bolt face during extraction. The leading edge (lip where the bullet is seated) of the casing drags on the right hand side of the chamber as the bolt is drawn back. Is this normal?
 
Ooookay, I took your advice aric84 and tried taking the scope off completely. Hey, look at that, works fine! It was hitting the knob on the forward scope ring.

Ugh I am retarded. I guess I can fall back on the fact that this is my first rifle to save a little face...nah I still feel like an idiot.
