How did the bolt catch tab break off?
Just failed. I started to notice the bolt not holding open on empty, and then it stopped feeding the next round almost at the same time.
Got home, took it apart and you can see it was a poorly made part. Looks almost like pot metal and the tang just broke. I didn't realize it until I got home as I was with some friends setting up 2 new AR's he got. I posted a pic in my Mod2 review on here.
Weird part, I put the E3 bolt, cam and firing pin into my PSA carrier and it cycled just fine when at the range. Obviously with the bolt catch broken, it still did not lock back on empty, but started feeding correctly.
Not sure what is up as I still have to inspected everything to see if it's something obvious. I didn't want to hold my bud up with his new AR so I just stuck it back in the case for later and saved some of the brass to inspect just in case too.
I am mailing the lower back to Ayan as I figured he is certified so I don't risk anything with the warranty.
Just sucks to pay that much and deal with issues. At least my PSA ran fine as well as my friends two new Premium Mid-length PSA he put together ran well too.
Hopefully I can do some investigating this weekend sometime to trouble shoot what is going on.
Lastly, the FTF was with Xtac, American Eagle M855, and cheap Wolf my bud had. At least I can rule out ammo for the most part...lol
