I have one and it is great. Locks in place good and stays on during extended fire. The post is held in with a small pin, same as the A2

Rough,
I have the YHM rail mounted front on my "YHM" rifle. This rifle has the YHM front (quad rail mounted sight) and rear (A2 style) BUIS, YHM M/L quad rail and the YHM Harris Bi-Pod mount. It is a RRA A4 upper and standard lower. This one rifle gets a lot of looks and questions at the range. It has an EOTech on top. I could have sold it many times, one shooter had his check book out.... 77Bronc |

I don't recommend using a big ass screwdriver to tighten these sights onto the rail...I just found out the hard way that's NOT a good idea
 .I snapped the end off, with about 1/4" of the end still screwed into the other side. I had one of those "oh shit, there's $70 down the drain" moments, but I took a little drill bit and backed it out. Time to order a new screw. Guess this one really is "hand tighten only". |

Fenian,
I forgot to mention, I have changed all of the big screws to smaller Allen socket head of the same pitch and diameter, I think they are 10-24's. Cut down to the right length and cold blued. Dab of service removable Loctite. I do not like those big screws hanging out. 77Bronc |

Great guys this sounds like a good way to go
the replacement screw idea is a great one I may have to try that. |

apparently this has been a recurring problem, so much so that they went to a larger screw for this sight, about 4 months after it came out. I talked to YHM today...I had just ordered something last night, right before I broke this screw, so I called this am and they're hooking me up with a replacement allen screw that replaces the old thumb screw. BTW, for anyone who's interested, they have the gas block/flip up sight towers back in stock...EVERYONE has been out of these for the last several weeks...so I picked up another one of those. |

For those interested in allen screws vs thumb screws. The correct screw for the YHM flip front and rear sights (YHM-9584, 9627, 9680,9680-A1)would be a 10-32 by 1 3/16" which is hard to find but a standard 10-32 by 1 1/4" is available in most hardware stores for about 10 cents. |
