| Hello, will the battlesight on the 11” troy alpha rail be able to fold all the way down with a mid-length system using a low-profile gas block or will there be interference? id really like to avoid the 13" alpha option. any input would be appreciated. |

I can answer that for you. I purchased a 11" Alpha with integrated sight for my 14.5" mid-length build. I used a Troy low-profile gas block and the sight will not fold down. The top of the gas block sits in the area where the sight folds down. Crap. This was my idea for my 2nd build. Plan B... |
| Unfortunately the 11" Alpha Rail with the built in sight is not compatible with a mid length and intermediate length gas system and the 13" Alpha Rail with the built in sight is not compatible with the rifle length gas system. We do however offer both lengths without a built in sight that will work. Thank you! |

i just got my new Alpha rail and the 13" did not work with my midlength shaved FSB but just barely, so i was able to shave down the front of the FSB more to make it work. So instead of the FSB being square on both sides the front tapers down to the barrel now to clear the built in sight.
Hope that makes sense. And also not to hijack your thread but mine came with the front sight moving from side to side quite a bit so i am in the process of trying to send it back to them to get fixed. I already started a thread on this issue. Overall im kinda disappointed with this rail. Just wanted to share my experience |

Here is my rail. The front sight clears the gas block by quite a comfortable margin. http://i51.photobucket.com/albums/f392/BiteyMcClaws/IMAG0659.jpg http://i51.photobucket.com/albums/f392/BiteyMcClaws/IMAG0662.jpg Do you have any sort of side to side movement in your front sight when it is in the up position? Mine does and i have contacted troy and they said the movement is normal. i dont see how it could have movement but hold zero. i am going to be sending mine back for one without the built in sight |

That would hold it in place nicely. Maybe a plastic washer or bushing? That's what I'd do. The front sight is a huge bonus, and it saves you from having to buy a separate one. |
