are you talking about the std. A2 front sight vs the pic railed gas block where you can add on flip up/other front sights? if so, the cut railed block gets rid of the A2 standing sight for better use w/ optics (no blur of the FS in the view) basically, the rail gives you the option to add on a flip up/screw on front sight, but if not, keep the line of sight for optics clean and clear still there to secure the gas tube though... |

Ahhhh ok. So the gas tube just attaches to the front sight base on standard ARs? Sorry, but I just recently got into guns and I'm still learning :) |

yea, basically the gas tube runs through the upper reciever, through the bbl nut's notches, over the bbl, through the front sight base/gas block (gas tube's big hole on the bottom goes upside down over the hole on the bbl, and you align the 2 smaller holes on the sides w/ the holes in the FSB/GB and add a pin to lock it in) www.ar15.com/forums/topic.html?b=3&f=4&t=226782--check this out no problem  --learning is fun!(i'm still learning too--troubleshooting the AR  )

To direct gas from the barrel into the Gas Tube. W/O it the rifle is a single shot. |

For that condition send the upper back and have them fix it. |

might have to do that... home remidies (checking the bbl torque/alignment and mallet tapping did not apprear to work)  |

it`s shoooting a couple feet to the right.????? does your rifle have a flash hider? If so, it might not be on straight, perhaps canted. Look around inside edge of the flash hider for a shiny spot where bullets may be hitting it when exiting barrel? Use a magnifiying glass if needed. if so return to dealer/factory.

more likely a canted FSB I'd think. Pretty sure a round hitting the FH would cause a hell of a lot more problems than just shooting to the right.
