[2020 PSA AR-9 Misfeed issues]

sorry to hear this in a new rifle, but these often need deburring and smoothing of internal edges. Also very sensitive to bullet shape. Mag height should be ok. If it’s not I’d return it. 

 

It's interesting that they do sell a barrel that appears to be nicely polished and also has a smooth feed notch/ramp...

I am trying ETS 31 mag this week and also 24 and 17 round Glock mags

 

starting with mag troubleshooting based on comments, then move on from there

Never fired before, very well lubed.

Bullets were slamming into the bottom of the barrel and jamming the bullet back into the casings.

 

One thing I noticed that was after clearing the jam, if I didn't slam back in the magazine, it seemed to work better.

 

I will try the ETS mags.

 

I thought I had read that OEM Glock was the best, but now hearing that they hate 33-round Glocks.

 

 

[2020 PSA AR-9 Misfeed issues]

Just received a new PSA AR-9.

 

Cleaned and lubed, and shot CCI 9mm 115 grain in a factory Glock 33-round stick.

 

5 misfeeds in the first 10 shots.

 

Really disappointed, and I was using Glock factory magazines because I had read that they were the most reliable.

 

Please help.
