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.
thread title change to reflect the true nature of your problem.-gotm4
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.
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
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.
If one of those primers fell into your lower receiver and you never recovered it then you need to take the hammer and trigger assemblies out and find that primer. If you aren’t trained on this then take it to an AR15/M16 certified gunsmith or armorer and have them do it. I had this happen to me once, I didn’t find the primer and it lodged under my trigger, between the trigger and lower receiver. This didn’t allow the trigger to work, dead gun.
Just looking at the brass it looks like it is way hot, were talking proof round hot, especially with the black scortching around the rim of the brass. I never shoot anyone’s reloads but mine. Like the other guys said, put some factory loaded ammo through your gun and I bet the problem goes away. I would also clean the chamber, bore, and bolt face, inspect the bolt lugs and the tip of the firing pin to make sure there was no damage done.
One rule of thumb is never shoot someone else’s handloaded/reloaded ammo–unless you trust them with your life and gun. Either there is something seriously wrong with powder/powder charge or that pocket is so loose there shouldn’t BE a primer in it…Send the remaining ammo back…And go factory or learn to roll your own
OP,
I had a similar ammo issue in my SR15 last week, while at a 2 day Tiger Swan carbine class. I had a blown primer, and the debris lodged in the firing pin channel in the bolt, locking the bolt into battery like a mug:mad:. I contacted Kevin B, who was most gracious and helpful (considering it was a Saturday AM), and managed to remedy the problem. The SR15 has 300 trouble free rounds thru it since last Sat, so I am once again :dirol:
The ammo in question for me was Royal Ordnance Radway Green SS109, 1989 manufacture.
I will reiterate what Todd.K said- DO NOT FIRE ANOTHER ROUND OF THAT AMMO!!
It’s showing dangerous high pressure signs. Not only was the primer blown out, the brass at the case head has flowed quite a bit. Not only has the primer pocket expanded but it’s elongated and the primer flash hole is greatly enlarged. By all rights that brass should have ruptured.
Be sure you inspect the extractor and bolt face for signs of damage.
The other possibility is an out of battery firing.
Either way, your Guardian Angel was working double overtime that day and you owe him a drink
For all that posted. Thanks for all the help. I probably have averted a catastrophic failure. I have contacted Tactical Ammunition and they are replacing all of it at no cost. They have great customer service. Thanks again, its why I love this board.
