Pennsylvania Firearm Owners Association
HB2011 and HB1243 Updates

So far, there hasn't been a 2nd Consideration vote on either of these bills. WE NEED TO KEEP UP THE PRESSURE, and continue to contact our legislators - ask them to tell House leadership to bring these bills to a vote! Ask them to vote YES on HB2011, and NO on the Universal Background Check amendment. In addition, the FOAC is requesting support for an amendment proposed to HB1243 (Mental Health Records for Firearms Purchases) that, if passed, will allow HB1243 to restore firearm rights to those who have recovered from a mental illness.

Default Brass ejection problems- AR-15

Good morning fellas, I'm having a slight problem regarding brass ejection on my AR-15. I've put around 1k ammo through it as of this writing- PMC Bronze and Prvi Partizan. For the most part, it runs fine with no problems. However, sometimes the brass will get caught in the ejection port and cause a jam. Usually its not a big deal, I safe the firearm and clear it out. Although something that truly frightened me happened at the range yesterday: The 2nd round in the mag flew out the barrel and the brass case became lodged above the bolt. This has never happened before. I put the weapon on safe, removed the magazine and took out the 3rd round that was jammed along with the spent brass. I then tried to separate the upper and lower half- to no avail. The charging handle was difficult to move back and forth because of the brass. After a few minutes of thinking, and staring dumbly at my wounded boom stick, I went into my range bag and took out my trusty multi-tool. I used the pliers to yank out(for lack of a better term) the dis functioning brass case. I'm sure all you other AR owners would have cringed when you heard that sound of scratching metal, I certainly did.

I maintain the weapon pretty well- regular cleaning and oiling. Is there anything else I can do to ensure this doesn't happen again? Did I load the mags wrong? Am I just retarded? I am very concerned about this. This firearm is my SHTF go-to weapon, the last thing I want to happen is an incurable jam in a life or death situation.

Sorry for the wall of text, thanks for reading. As always, any/all input is much obliged.

Sounds like short stroking. Check out this link and read.

I had a short-stroking issue due to my gas block hole not being lined up properly with the hole in the barrel. If it's short-stroking, it generally does it all the time, doesn't it? I know the test for it is to load 1 rd and fire the AR to see if the bolt locks back. That basically tells you if the bolt was knocked back past the catch.

Do you ever clean the gas tube or the tube on the top of the bolt (sorry for my lack of lingo) Perhaps if that area is dirty or not sealing well, it could contribute to an intermittent short-stroke. Also, have you checked the piston rings?

Check your gas key. It needs to be tight.

Don't shove anything down the gas tube....no oil there either.

If I read this correctly, was anything on top of the bolt damaged?

I am thinking also it may well be a shitty lot of ammo.

Thanks for the input. I'm heading to the range later today, I want to get there before it closes for a few weeks. Hopefully there will be no problems regarding brass ejection.

Forgive my ignorance but what is the Gas Key and how do you check it?

I had my Delton build at the range for only the 3rd time last week and had 3 instances of brass not coming all the way out and getting jammed with the next round. This only happened when I switched to standing shots. Limp shouldering?

Ammo was Remington 55gr UMC.

I also has problems with the Remington 55 grain. Two questions for ya:

1. What front sight do you have? Is it by any chance the YHM flip up?
2. When you look at the bolt face, are there flakes of brass on it?

I got a Del-ton build and my problem was due to intermittent short stroking due to my front sight / gas block not being lined up with the hole in the barrel. When I took it apart and fixed that, my AR has been awesome and reliable. Then again, I also only shoot Wolf in it now so there is no more brass flakes on my bolt.
