What ammo are you shooting?
youre trying to educate a bunch of people who believe what they heard on youtube more than simple physics.. you can overlubricate a rifle and then i get this line of misinformation about how the ar-15 is a "bearing" or some crap like that, not realizing you can put too much lube in a bearing too
i think they need to read up on a thing called hydrodynamic drag which occurs when bearings are over-lubricated which results in drag on the moving components that has to push its way through the piles and globs of dripping gun oil which can have as adverse of an effect as running dry
no, it shows one video, one magazine in a controlled environment and you assume this disproves documented physics because omg.. you watched it on youtubeOver lubing an AR with oil doesn't cause malfunctions

There is no reason to soak a rifle like this, but it shows that too much lube isn't the problem

you have way too much faith in youtube videos, i dont care if its larry vickers, santa clause, or jesus doing the youtube video, running weapons dripping wet with lube is bad information and telling someone to overlube it an attempt to fix the problem is just plain stupidThe video is only a sample of one, but it's an extreme sample, far beyond the amount of oil we're seeing in the photos posted by OldSchool. In fact, the amount of lube on the OldSchool's carrier is nothing compared to the lube and fouling I've had build up on the carrier of my own AR and it never caused a malfunction.
The video was made by Larry Vickers, a well vetted and trusted source of information and knowledge within the community. He has years of advanced training and experience and has been there done that. If you think the results achieved in the video is a fluke, then repeat the test for yourself and see what happens
Remove your gas block and check the gas port size. You can at least eliminate that and it's easy enough. When you put it back you have to make sure everything is aligned and the pins are installed correctly.
There's no reason he can't. But there's no reason he should. And a few reasons he shouldn't.is there any reason he couldnt stick a pipe cleaner or copper wire down the gas block from the front to probe the gas port hole?
its a used gun, who knows what parts have been replaced and of what condition those parts were, and what powder has been used in it in the past or how its been cleaned.. it would rule out that possibility with no harm to the rifleThere's no reason he can't. But there's no reason he should. And a few reasons he shouldn't.
same procedure checks and rules out both, once thats ruled out then you can be certain its BCG related.. thats all im saying, rule out the stuff thats easy to rule outThe only way I can see the tube and port being stopped up is, it was used only with subsonic that used a very dirty powder... but following up with supers should blow it clear... I would bet on an out of line gas block before a stopped up tube...

1) I like the accuracy I got out of it but it didn't cycle. The shop gunsmith took a crack at it and replaced the BCG group with a Nickel Boron one. It no cycles but not 100% of the time. He says he got 15 rounds cycling fully.
2) Ok, the gas tube got replaced with the BCG and it got a through cleaning.
3) Ok, this is an Eagle Arms AR15A2; 20" barrel (Rifle non-adjustable stock) the upper and lower are possibly the tightest I've ever seen on an AR. The gas rings in the BCG are in good condition. The rifle was extremely dry on it first run when it wouldn't cycle. I've never limp wristed a pistol but that is how I would describe the intermittent cycling I'm seeing now. When we shoot it and it doesn't cycle I can't tell if the BCG isn't coming back at all or just isn't coming back far enough to chamber the next round and is riding on top of the next round. Next I'm going to try drowning the BCG in lube.
4)Ok, still getting weird. Single round in the mag it locks back most of the time.
Running it wet with oil helped some. I wasn't real consistent with the ammo we were using so that is still a variable.
I was however getting these nasty jams more than I like Its almost like its not unlocking and ejecting properly. Listening to the buffer tube sometimes there is no recoil pulse(no spring sound coming from the buffer tube). I'm going to see if I can find someone local to me to look at the gas block and port alignment.
5) its a complete Bolt group there is just a lot of oil on it! Gas tube is new. I keep this rifle separate from my residence so unfortunately I don't have ready access to it for pictures.
So checking the gas port size is like an unnecessary medical procedure?Checking the gas port diameter and location are on the list of things to check, but they are down the list a ways for a reason. Those aren't common things to be wrong and checking them isn't trivial, plus there is the risk of collateral damage.
It's like going to a new doc for a checkup and before he takes your temperature and blood pressure he orders a barium enema. A barium enema can be a useful test, but usually he goes there for a specific set of symptoms.
I'm not seeing the symptoms that point to a clogged gas tube, or a misaligned and/or a undersize gas port. The symptoms and diagnostics as reported by the OP are:
Would you blame him? LOLWe won't know if the OP doesn't follow up with us ?
Has anyone suggested replacing the gas tube?I picked up an A2 style AR with a 20" barrel from a local pawn shop lets call it close to dirt cheap. I like the accuracy I got out of it but it didn't cycle. The shop gunsmith took a crack at it and replaced the BCG group with a Nickel Boron one. It no cycles but not 100% of the time. He says he got 15 rounds cycling fully.
I don't care to take it back again and its not going to be a home defense gun so perfect reliability isn't a concern.
Some thoughts; I'm using brand new 10 & 30 round Pmags. Would moving to a lighter buffer or spring help?
Thanks,
