Grrrr!!!! SO ANGRY!!!! I got my AR pistol put together but the POS BCG WON'T FIT!!!!!! It's like they took a perfectly fitting BCG and put on WAAAAY too much nickel boron coating! I tried working it back and forth a bit but only managed to get it stuck--had to bang it out with a brass punch! Waste of money! Lesson learned: if it says "PTAC" run the other way!

The BCG from my RRA fit no problem. The PTAC wouldn't fit the pistol OR the RRA. I HATE wasting money on junk that doESN't work. Thing is, I THOUGHT I was ordering a PSA NOT a PTAC at the time. Was looking at both and pushed "buy" on the wrong one.
