So let me give you a run down with whats going on maybe someone can help. The first trip to the range I fired 40 168gr FGMMs 50 magtech 150gr and 20 180gr Winchester just to see what it liked. Out of these I had 1 stove pipe. I didn't think anything of it because it was the magtech 150s. Being cheep ammo I figured it was something with the ammunition or maybe the spring was just breaking in.
After that my Magpul PRS came in the mail and I installed it with all DPMS buffer tube, LR-308 rifle length buffer spring and LR-308 buffer. The next few trips to the range I fired a total of 190 168gr FGMMs with 1 failure to feed where it mangled the round Like the one in the picture. Today I had 1 stove pipe and 2 failures to feed on 2 different types of ammunition and different mags. The Stove pipe was from the 168s FGMM in the Magpul Pmag and the FTF was from a Lake city 147gr in the Pof P25 mag and a 168gr FGMM in the P mag. Today I fired a total of 85 rounds and to have 3 failures is unacceptable. I can usually trouble shoot any consistent problems involving firearms but I am stumped on this one it just seems random to me... Maybe someone can help me out?
Along with this the brass ejection is erratic. Sometimes it will eject the same ammunition 10ft or just lay it on the table like you dropped it out of a bolt gun. Also I found out that it cycles without a suppressor with the gas plug turned on suppressed.
Here are pictures of the FTF brass.
There is a deep scratch on the case.
Deep dent in the neck.
Neck is bent to the point the bullet was easily removed by hand.
