Aero m5 build .308
I posted on this thread about 3 months ago maybe longer. Ever since then I have put so much money into this build I’m done with it. I’m honestly guessing my barrel is out of spec and the gas port needs to be opened up. It’s a 18in .308 m5 upper with a aero lower I have a geissele 2 stage trigger spike tactical internals a H5 buffer tube I’ve tried all the buffer weights a H1 H2 H3. I keep having FTF failure to lock back. I also have to mortar out each round when I chamber a round I tired the plunk test the bullet is seated in the chamber it doesn’t come out with out force . I’m honest fed up with this build. I did contact aero and I’m just waiting for a shipping label to get a brand new upper I’m don’t with this one. Does anyone else here have the same issues.
Edit: yes I clean the fuck out the chamber. Made it worse actually had to send it to a gun smith with a live round stuck in there.
