I just got a #40, and am getting ready to mount it. Question: I understand the large aperature is for 250yd and the small one is for 500yd. Now, how are you supposed to use the 'notch' on top of the 500 yd sight? And what do you use the 'horizon line' for? Regards, Jeremy |

I have wondered the same thing about the "horizon" line. I just figured arms just cut the top off the sight so that it would be flush when the sight is folded down. On the arms with the standard A2 sights, the small aperature sticks up alittle when the sight is folded down. |

Ditch the original Aperture and put a stock one in your 40. That's what I did... the Horizon line is gay and just a marketing tool to cover the fact they needed to shave it flat so it would not stick up when folded. And how many 500-Meter shots is a guy gonna make with BUIS on a 5.56m.... Don't waste you energy putting a lot of thought in to it..... replace and enjoy |

While I wont disagree that many have no use for the horizon line, I surely disagree that ARMS making it that was its some sort of "marketing tool". Why on earth do you feel they "needed top shave it flat", especially since they offer the #40A2 as an option? Trade apps if you like, but why in the hell do you make up your own story about why it was done. And if it isnt made up, please tell me where you got this info and how it is ligit? |

I have no concrete proof as to why they did it, Just my Opinion based on owning it and looking at the design of it. What other logical reason would any designer have to take a rear sight aperture and cut it in half. What would you call a "Horizon" line?? if not a Marketing tool.... We are still entitled to have our opinions.....or did I miss the memo on that one............ |

Harv, you are entitled to your opinion, so long as you remember thats what it is. There was no memo to miss on that. However, you must have missed the memo saying that if you have an opinion and would like to share it, it is unwise to state it in such a manner that may lead others to believe it is fact. For example: Hmmm, why did they make the horizon cut on the #40? Have you tried fitting an ACOG over a #40A2? chances are probably not, otherwise you would know it wouldnt fit. Have you tried fitting an ACOG over a #40 with the horizon cut? chances are, probably not, otherwise you might realize that the cut allows it to work. That's my opinion on one reason maybe they did it like that? Or who knows, maybe you're right. Maybe it is just a "ploy"  Happy Easter

What is the “horizon line” used for anyways? Celestial navigation?  Never mind, found it.

I agree with you that the cut is there for clearance and that is it's sole purpose. Where I believe the marketing comes into play is the fact that their are no Instructions on how to use this great feature that was Engineered for the sole purpose of assisting in lead corrections and to help prevent cant...... Anyone see the Instructions ?????? I must of missed them. Advertising a feature with out instructing the user as to how that feature works is a marketing ploy in my book. If it was milled simply for the purpose of allowing an ACOG to fit over it (which I believe it was) then why the extra added sales pitch for this "Horizon " line... I will add in my future post's that it is just my opinion as I Agree with you whole heartily that I need to back up a statement like that with facts and I do not want to mislead others.....my bad....
