    He has stated that it was the "standard" buffer from Vltor. According to their own site, they ship the kits with the "standard" buffer and only offer "HEAVIER" than standard buffers. So he already has the lightest A5 buffer Vltor offers.

    Problem is, if the carrier is traveling so far rearward that its hitting the rear of the receiver, im wondering if he was shipped a standard carbine buffer and not an A5. The shorter standard size carbine buffer stuck into the longer A5 extension would allow the over travel of the carrier and the resulting damage to the lower...

    OP can you supply a pick of your buffer? Can you measure the overall length as well?

    That is incorrect, and you have already been told that it is incorrect once before. Please stop re-posting inaccurate information. Vltor makes two buffers that are lighter than the standard A5 buffer. They are listed in the Vltor store.

    The OP already stated that he checked and this is not the case, but I guess you didn't bother to read that either?

    Clearly its "not the case", just look at his RE/lower pic that was posted...

I bought the VLTOR A-5 for a reason, and want to try to get it working that way first before I ditch the whole thing. If they mean just using a lighter buffer, then I'd love to, but VLTOR's buffers are impossible to find right now. I'm working on swapping out some weights in my A5H2 buffer to lighten it up, but I haven't gotten around to it yet. I've been on vacation for the past week.

    I also contacted VLTOR. After a few e-mails back and forth explaining the problem, I haven't heard from them in a few days.
    Do you not have the ability to utilize a "standard" receiver extension with a carbine buffer? As in; borrow from a friend?

    My advice to to do what they are telling you to do and if that does not solve the problem, get a return authorization so that they can fix their product. What you are describing does not sound like a receiver extension/action spring/buffer issue, however, you either play by their rules or take full responsibility for getting it back up and running.

    Adams Arms/VLTOR A5 fail to eject

    Yeah, I'm going to try to get ahold of a friend so we can go out and switch uppers and see what the deal is. I meant if that works, I'm not going to just settle for getting rid of the A5 and calling it a day. But that is a part of my troubleshooting plan going forward. Unfortunately I'll be lucky if I can get to the range this coming weekend... It may be 2 weeks before I can try anything. I appreciate all the help y'all have given me.

    Let me make sure I understand you:

    If you try the upper on a standard lower, and it works, you are not going to ditch the part on your rifle that is causing your upper not to run; because you believe that it is going to make the gun run better, even though you have no point of comparison?

    Pretty much, minus all the stuff about what I "believe". It's more like, this is the way I chose to build my gun, in theory it should work just fine, so I am going to make it work. Call it the engineer in me, but I'm not going to just drop the part because it's giving me a headache.

    Not to mention, just because my upper will (hypothetically) cycle on another lower with a carbine RE, doesn't mean my upper will cycle on my lower with a carbine RE. Could find out something else is wrong with my lower. Or it might not fire at all and be a defective upper. Time will tell...

    Good luck with that, and I mean it in a honest way (non-). I've learned things in this thread and I hope you do figure things out for the benefit of all of us gaining more understanding.

    I bet the engineer in you would like to find the real cause of the problem. The best way to do this is to isolate the problem component(s), starting with upper/lower swaps with a couple of known good guns. One of the lowers should have a carbine RE and buffer. Keep in mind, both your upper and lower could be at fault. Until you do this, you're running in circles and anything that fixes the problem would be blind luck.

    I hope this is a hobby gun for you, and you have the luxury of tinkering with it until it runs. If you want something that just plain works... you don't need to look far on this forum.

    One last idea, if your buffer and spring are the correct version for your A5 I have to wonder if the anti tilt skids on the rear of the AA bolt may have something to do with the abnormal wear in the buffer tube, all that contact/friction inside the tube cant be helping things and maybe the two just aren't compatible?

    That being said have fun with your "Project" gun and I hope it works out for you.
    We are all inclined to judge ourselves by our ideals; others, by their acts.

    Plenty of people have given you advice on how to troubleshoot this. If you choose to ignore it there is nothing more we can do for you.
