    There is something wrong with my ammo

    I've had my SR-15 for awhile, and have put only the same ammunition through it for that time. Approx 600 rounds. I've never had this issue before, but a couple of days ago, I couldn't get through even two magazines before my rifle got brass stuck in the chamber and when I looked the primer was out. I was able to get the brass out and fired a few more rounds before it did it again. This time I couldn't extract the brass. After finally gettin it out, it did it a third time this time the bolt was stuck and I couldn't get it out. I used a cleaning rod and was able to get it out. I kept the brass that was stuck and it looks squished toward the end with the primer. The primer had fallen out as well because the end was deformed. It had never done this before and maybe its my noob status, but is there something I can do? Or should I get professional help? Thanks.

    What kind of ammo is it?

    Sounds like an ammo problem.
    Popped primers is am indication of excessive chamber pressure or bad ammo.
    What ammo manufacturer and type?
    It is also potentially a chamber problem, but that's not the first thing I would be looking at with a KAC.

    Might be a bad batch of ammo. Did you take out the popped primer each time it happened?

    I'm using reloads from Tactical Ammunition in Oregon. I've bought from them and never had a problem....but that would explain, but not all of the ammo was doing it....here are the pics of the brass in question. The loads are 55gr FMJ in Lake City Brass loaded to mil-spec standards. If its the ammo, it would suck because I bought 500 of them

    Yeah I did. Of course it fell in to all the nether regions of the trigger group.

    Unfortunately this is what happens when you buy reloaded ammo. Whether you had issues in the past or not is irrelevant.

    I would contact them and ask if they have a guarantee.

    I would also go buy some small amount of milspec ammo (which I believe is recommended by KAC) and see what happens. My guess is that it stops.

    The biggest problem with reloads is a lack of consistency. I wouldn't fire another round of that stuff. You might just lose your $2K investment if you do. I would try the rifle with some known factory 5.56 pressure ammo from a reliable source and then probably contact the reloader for a refund. My guess is that your problem will go away with true, in-spec ammo.

    Also, you might also consider a new thread title until you determine the exact cause of the issue. Good luck!

    Yeah as far as there being something wrong with the gun I wasn't too sure, and in all ways I'm happy with it. I know I spent my money wisely and realize that its most likely not the rifle.
