AAAG! Failure to eject! EA M15

GrassHoppa · 11-16-2002, 03:05 PM

Hmm, guys....if I can rattle your collective brains here to find out what might be causing this annoying problem with my AR15. I had sort of sporattic FTE with my new EA M15. It had never been shot so I don't think it needed cleaning

and I was using some 55g Winchester FMJ. I'm not sure what elese would be causing it to not eject some shells and once it got jammed on one cartridge but I think that was a fluke. As long as the spent casing got out, the next one loaded fine. So, what else could it be? I'm really a total newb with AR's so if anyone can throw in some suggestions, I'd be gratefull. Also I'm using the Mags that came with the rifle. These Armalite ones...look like they might be plasict but they're not. I also noticed that one mag is slightly twisted, could that be causing a problem?

Well, you may be right, it probably didn't need a cleaning, but i've found that NIB AR's tend to need quite a bit of lubrication. Enough that you would normally thing it excessive, particularly on the bolt and carrier. This will last until the gun has a chance to break/wear in. Once that is complete, normal lubrication can be resumed. Worth a shot at least, and should help diagnose whether or not its something else :>...

later,
AJ

Thanks AJ. I'll give that a whirl.

Just bought a NIB Colt HBAR 20" A2 and had a similar issue, but just once. I used Rem .223's for the first 100 rounds during break-in, cleaned after every 5th shot, then loaded up about 100 UMC 55 gr FMJ, and had one stovepipe. It does seem that excessive lube is called for at first. After 300 rounds it was cycling flawlessly. If you still have problems try different types of ammo until you get one that seems to behave itself.

THanks Mico! I have yet to get back to the range...

What are you using to lube your bolt??? I use wheel bearing grease or a light (and or) medium military grease. Maybe if you are just using oil, its not enough??? Are you getting everywhere you need to lube??? Just some thoughts...

Mico · 11-20-2002, 12:04 PM

That's a good point... been using break-free CLP spray, which acts as both a lube AND a powder solvent. I'm guessing part of the problem may harken back to the early days of the M-16, where a dirty chamber significantly affects performance.

I've noted that oil+powder residue = sludge, and even in minute quantities some guns become seriously unhappy when fed enough. Break Free overcomes the issue. Since I started using it on one gun, I now use it on all of them, about a dozen or so. It's fantastic stuff and may clear up the issue.

Hope this helps.

Break-Free CLP is good stuff--I use it on all of my toys.

Make sure the mag you are using has a good spring. After LOTS of testing,I've come to the conclusion that the military 30rd with the green follower are the BEST. I use MILTEC now on all my guns,and found it superior as a final assembly lube.:assult:

And don't forget the rule "a little goes a long way" when applying assembly lube.

Clean it! Lube it! And enjoy! When new she needs los of tender love and care. As was previously mentioned in the Colt post, clean her frequently after relatively few rounds. 20-25. After 100 -200 she should start to loosen up. however, next time you take her out she will be cold and may requiire more of the same treatment. After the first 1000 she should purr like a cat. Try to stay away from the grease. She wasn't designed for it and when it gets hot it liquifies and gunks up the lower receiver. Remember she is, after all, like a women and needs to be treated like a lady first.:assult:
