I have a Stoner BCG and PSA BCG , both unused and got them mixed up.
There are very little visual differences in side by side comparison to me, although one has numbers/letters rolled in top of gas key set screws. I know Stoner is 8620 vs Carp 158 for PSA . I want to send Stoner back to vendor. Can anyone help? |

My PSA does not have PSA logo engraved.
Also the BCG in pics above has only an M rolled into bolt The one I believe is the PSA has MPI rolled into bolt. Also note the number 5 between Gas key screws in pic, the letters rolled into screws appear to be YES or YFS, and a circle on that gas key at top rear of key. Here is pic of BCG's GAS KEY'S for side by side. http://i88.photobucket.com/albums/k197/bone2fish/gaskey_zps4adb834c.jpg Thanks |

for those that dont know YFS= cheap made in taiwan crap, not machined bolts!!! Quoted:

Stoner has no marks on top. PSA is stamped. operator.... Edited to add: PSA gas key bolts also marked YFS. for those that dont know YFS= cheap made in taiwan crap, not machined bolts!!! Does that just refer to the gas key? Or is the bolt really like forged or something? |

Depending on the description of material that is called out by either mfg, you could narrow it down by that. I don't know why people these days that worry about all the MIL-Spec stuff out there are accepting these gas keys that are flooding the market nowadays. Thank you, Mike in MN |

In reference to the picture posted above the Stoner is the top BCG and the PSA is the bottom BCG. |

Quoted: I just received an e-mail from PSA customer service stating their BGC is the one with no markings the top pic of side by side. I was hoping someone who owned a Stoner BCG could verify. Thanks, bonegunner Scroll down for picture of PSA BCG. |

my PSA Premium BCG doesn't have any markings on the top of the gas key or the screws.. PSA also sell P-Tac BCGs, i think those are the ones with the marked gas key Here is my PSA Premium (#1) and my PSA Blemished(#2) I ordered a few weeks ago |

After reading responses/links to my origional post, I e-mailed PSA CS to ask for help resolving my BCG issues.
I asked for a return to store for store credit. I told them that the BCG had never been fired or even put into a rifle. The gas key/staking is crappy with cheap YFS screws and my bolt is not MPI as advertised . I got one shipped with only M on bolt as some others did. Yesterday I got a reply from "customer service" stating that since I had purchased in April that there was nothing he could do to help me as they have a 30 return policy. He finished by saying that he appreciated my business and hoped I have a good day. Now that response shows some real customer appreciation. My reply was... Then your company policy is if you make a mistake and customer does not figure it out in 30 days ,then too bad for customer. I also asked for name of customer service mgr. Have not gotten a response yet. I will admit to being a newbie regarding AR parts I am getting educated quickly...at a cost of course. bonegunner |
