| I bought THIS barrel from PSA and it didn't come drilled for a FSB on the bottom, meaning I can only use a clamp on block now. Is that supposed to be that way? |

Damn, thanks guys. Now I need a new barrel, ADCO is backed up as it is so that would take too long. Anyone have any 14.5/14.7in barrels in stock? (Any style other than HBAR) Why do you need a new barrel? Do you have a FSB that needs to be installed? I would just put a set screw gas block and shoot it as is until things calm down. If properly installed they don't move. |

(Any style other than HBAR) you dont need a new barrel, if it was drilled, and you have a FSB that is drilled, they wouldnt fit anyway, they are drilled at the same time. |

I was under the impression that all taper pins on FSB were the same specs? (I have an A1 Slick Side upper and Non-F Marked FSB I wanted to use the barrel with) |

Some guys have gotten lucky, but it is very uncommon to get lucky and have a new FSB fit a barrel that has already been drilled for a FSB from the factory. |

The FSB would come with predrilled pilot hole for each pin. A fixture would hold the FSB on the barrel in the correct placement. A pilot hole is then dilled on the edge of the barrel. A taper pin reamer is then used through both pieces. There is not a exact depth set for how far you go which makes for a variation and each barrel/FSG slightly different.
Put a lopro on or purchase a barrel with a FSB preinstalled. |

You bought a Mid length gassed barrel- you can't put an Aframe gas block on them! They are made for low profile blocks!  It pays to read ! Apparently you are the one who needs to brush up on their reading skills. Gas block compatibility is limited by the journal size on the barrel; bull barrel (.936" diameter), standard (.750" diameter) and lightweight (.625" diameter). Use of an A2 or F marked front sight base depends on the application; obviously a FSB cannot fit under a handguard, but can be used on a barrel with carbine, midlength, intermediate, or rifle length gas systems as long as the proper length gas tube is used.

| Ha, I wish I would have gotten my barrel from PSA without a FSB attached. Then I could have sent it to ADCO to have them install the FSB correctly. PSA is a company with super shitty customer service. The barrel they sent me has a canted FSB that allows for almost zero windage adjustment. Whoever drilled the barrel and installed the FSB must have taken 5 Adderall, and shot a spoon of smack, before getting to their work bench to "drill" my barrel... |

(Any style other than HBAR) Where did you hear that? Last I saw BigBore post, he said, "We are still turning around 95% of all shop work in about week or less.". How is that backed up or too long? Send it to ADCO /thread
