Hi.

I have a PSA AR-9 that has now broken the cartridge off in the breach twice. After the first time, I replaced the buffer with a long, 10.5 oz Spikes buffer but this last Saturday it did it again. I do use reman ammo - could this be the problem?

Any advice or insight appreciated because it sucks not finishing a match!!!

Thanks

Any issue I've ever had like that was bad ammo, only other thing I could think of is timing, maybe it's comming outta battery before the case has lost enough energy and is splitting case... Idk, I have never used it but they say palmetto has the best customer service... Maybe give them a shot

Have you tried using it with Winchester White Box ammo? I would try factory brass ammo before anything else.

PSA has a short chamber. Most factory ammo should be fine but reloads will have to be loaded short.
Is the bullet staying in the chamber when unloading or is the brass breaking?

Brass is breaking. Basically it is pulling the back off the cartridge, leaving a "brass tube" in the chamber. Contacted PSA and they want me to send it back so I assume there is something not quite right.

im sure that's the only way they can fix it huh...Like I said im pretty sure they have one of those no questions asked 100%warrenty..... Personally I would try diff factory new ammo in it first or try virgin brass reloads before I sent it in for repair

Probably stepped brass. There is a bunch of it out there. The brass has a thin area on the front and is thicker in the back. Tends to beak off at the step. Pretty common issue especially in reman ammo.

It’s either the stepped brass or rhe chamber os bad out of round. Leaning more to the stepped brass. Had a friend that had two of those separations in one match.

PSA is an incredible company that backs everything they sell. Contact them, and they will have you send it back to be repaired or replaced. They look at it as an opportunity for them to improve as well. I had ordered a side charging 300 BLK upper from them and it would jam picking up the next factory round. I took pictures, they said send it back and they had a new upper on my doorstep by weeks end. That gun is 100% with any ammo all the time. 110-220gr. Factory/Reloads... and very accurate!! PSA will take care of you!!!

Oh, your problem sounds like a chamber issue... possibly burs or something with the dimensions. (They will most likely swap your barrel.) My PSA AR-9 eats everything I feed it... even aluminum cases and spits them out with no damage.

Nope, nope and nope. It is NOT ammo related.

Been thru this already. Lemme find the thread. It’s the design, not the ammo.

PSA will in all likelihood replace the upper and pay for shipping on your return, etc.
the problem is the design. The bolt on these hybrids makes up the last couple millimeters of the *chamber* and that small gap leaves the case wall exposed enough to expand and rupture, due to being unsupported. I’ve gotten away from this design altogether.

Thanks Guys. PSA sent me a shipping label and my rifle arrived there this morning. They did not ask any questions so I assume, like Magdump said, it is a known issue. I look forward to hearing back from them.

Good luck man. I hope you get straight quick

Shout out to Palmetto State Armory for great service. I received my gun back yesterday. They replaced the barrel as well as the disconnector spring. Time will tell if it solves the problem but the no questions asked service is awesome

Glad they fixed your issue for you. Hopefully, all is now good.

On a side note I took mine out on Father's day and shot about 200 rounds of 147gr FMJ through it with the suppressor on it and it is Hollywood quiet all you hear is the mechanical noises of the gun and the thwack as it hits the backstop.

Gotta love that!

Glad PSA did right by you man. Only challenge is getting somebody on the line. After that, you’re usually home free.
