| I have read a lot on this site about iron sights and the FAQ about BUIS. I think I have narrowed my decision down to the ARMS 40A, 40L, or the YHM flip up rear sight. I would like any input on these and why I should or shouldn't get one of these. Which one would you chose? Thanks for the help. BTW I am going to actually shoot with these sights for a while until I am confident with them and save up money for some better optics. |

Welcome to the site. Have you seen the Troy BUIS? They are nice. I have an ARMS 40L and it's been okay. I've never been too crazy about the spring activation though. I had a Bushmaster (YHM-made) flip-up that I like a lot. It just sat a little high when closed, so it wouldn't fit under the scope I wanted on the rifle. That's why I switched to the ARMS 40L. I switched all my flip-ups to fixed BUIS options on my rifles with Aimpoints. I like a fixed BUIS much better for these kinds of optics. If you go that route, the LMT is nice, but the LaRue is much nicer. If you do need the flip-up, you might want to also look at the Troy. Between the ones you listed, if the spring doesn't bother you, get the ARMS. If you want something that lock in place and you don't need to worry about a spring wearing out, the YHM will be just fine (and cheaper too, IIRC). HTH |
| The only flip up BUIS I have any experience with are the YHM front and rear. I like them both - seem to be well made, and I feel like I got a good value. Granted, I don't use my AR for combat or anything serious. I had the same problem as Bookhound and can't fit the rear YHM under my MR/T scope so I am looking for alternatives. |

I like the ARMS system. Their method of locking on the rail is more positive than the others (the sight needs to be slid on). Also once flipped up you can't knock it down (it will spring right back up). Both my ARMS#40s are the standard model - but if I were buying today I'd look real hard at the #40L - it lower and if Jack is right you can get it so the two apertures are on the same plane (which I really like). |
| I have a 40-L and it appears that the two aperatures are on the same plane. On the 40-L, the small aperature is simply a "cover" with a small hole that flips up in front of the large aperature. Next time I get a chance, I'll get the calipers out and see what the deal is. |
