Need to buy a backup pair but there are so many to choose from. I cannot decide.

I have only have used the MI low profile rear sight and the plastic magpul set.

What do yall think is the best? I would love to hear your opinions on:

1) Front folding site to go on a rail
2) Folding site for the rear.

Please give me the model type too so that I can track it down and purchase it.

Thanks

I would say the best is subjective, but to me it's probably the Troy BUIS set.

Besides the Troys, these are worth a look:

- KAC Micro BUIS
- KAC front BUIS

very subjective..

I have PRI front flip up on my SBR and my 18"SS (yes i know u said rail mount)

I have Wilson Combat BUIS on the rear. At the time, it was one of the only rear flip ups that had Elevation AND windage adjustments and it was the flattest laying site which is what I wanted.

Another vote for Troy. My MagPul MBUS set is also excellent if you're on a budget.

I like the KAC 200-600m for rear, and either KAC or Troy for front.

I have a Samson rear sight on the way. I have read good things about their front sight but I guess their rear sight is a fairly new product because I can't find any info on it. Looks comparable to the Troy. Anyone have experience with the Samson rear flip-up sight?

It's this one. Nice looking sight in my opinion.

Link Posted: 3/10/2010 9:27:41 AM EDT
I think the best rear buis is the GG&G MAD BUIS and if you don't you should try one... so solid, no play or side to side movement whatsoever. However I can not say the same for their quick flip front sight. It has a fraction of movement which equals a degree of inaccuracy. Sure does look nice though... a.r.m.s makes good buis. cant go wrong with troy. I like the troy's with Larue logos, would love ot have those

DPMS -rear sight is narrow , no sight obtructions . Front sight folds forward and has two hight ajustments for gas block or rail mounting . And I have a set for sale .LOL .

I am not trying to be a smart ass, but I never understood the whole flip up front sight thing to begin with. What is wrong with using a standard FSB? If using a magnified optic, you cant see it. It doesnt show up in the scope. If you are using a red dot, you can co-witness right?

I have put several scopes on rifles with front sight posts and had no problems. Am I missing something? I guess if you want to use a red dot, and not co-witness, then the flip up is necessary.

Someone let me know what the advantage of the flip down front is exactly please.

I haven't used Troy, but I like my YHM Q.D.S. (MSRP $207.00 from YHM)

If you need to mount a set under a big scope tube, they are excellent.

YHM is very proud to introduce the newest addition to our product lineup. The Quick Deploy Sight System features an automatic deploy system that springs the sight up with the push of a button. Both front and rear sights lock positively in the folded and deployed positions and are made from aircraft quality aluminum and hardcoated to military specifications.

The rear sight is available with either a single large peep, single small peep, or dual peep aperture. When folded the sight measures just .435 inches from the rail.

The front sight mounts on the same plane as the rear and uses standard hardware. It is available with either a hooded or standard stem. When folded the sight measures just .435 inches from the rail.

Personal preference. Some dont like the FSB in the picture with thier red dot or at lower magnification on thier scopes.

Troy hands down. They are $ though.

This.

KAC is my favorite followed by Troy.

thanks for the feedback, keep it coming. I'm googling these as people post more and more models. There are so many models available so you guys are saving me a ton of time. Thanks.

I guess I should have said that I was looking for the sites on 2 different rifles.

The SBR needs a rear BUIS. It has a fixed front sight post. It currently has an Aimpoint with the Larue LT-129 mount.

My 16" BM needs a folding front site on the end of its rail. Running an 4X optic on it.
Link Posted: 3/10/2010 9:48:57 AM EDT
What's the difference between the standard rear and micro rear sights? Its hard for me to tell by the photos in the KAC site. Is it the size of the aperture, the knobs, overall dimensions of the base? Just looking for clarification.

I dont like the looks of the FSB..Im also using a 1 x 4 power scope, so at 1 x it shows up, maybe fuzzy but still there. I also dont think an AR "Flows" looks wise with FSB and rear flip ups. FSB and A1 or A2 carry handle upper is fine. Also, I cant stand the looks of rail mounted Flip ups. it breaks up the flow of the rails also. IMO, it looks like it just doesnt belong up there.

Here is my 18" SS with PRI. but it really comes down to preference. The only advantage would be 1) wont be in the site picture , fuzzy or not and 2) wont snag on anything



Link Posted: 3/10/2010 10:43:40 AM EDT
Troy folding rear BUIS ,and I don't use front folding BUIS .

I prefer to use a fold down rear to get it out of in front of my optic ,but I always have a
standard A frame front sight .

Less to mess with if the BUIS are needed in an emergency ,less chance of a mechanical failure,
and less chance of having the combined movement of front and rear sights shifting your POI .

I personally prefer the Troy BUIS.

I have MI BUIS on both of mine but I recently came across a set of Troy's. I have no complaints about my MI BUIS but the Troy sight's just feel so much better. Next AR will have Troy sights.

Great price for Troy sights

The micro sights are smaller/lighter with a slimmer profile. I love them.

The micro is lower so it can fit under a scope.

You can't fit a 13" rail on even a rifle length gas system with an stock FSB, so flip up it is.

That and the origional FSB is heavy in comparison to a flip up, just more weight out at the muzzle end.

I've used a few different flip up sights both front and rear, Troy wins, but is expensive. Get what you can afford, it doesn't necessarily have to be the best or most expensive, it is a back up sighting system after all.

No, the micro is simply a smaller, slimmer version, mainly to provide cost savings to the customer (a KAC representative stated that the micros were developed to cater to the commercial market, to compete with troys and the like). The original KAC sights fit just fine under scopes.

explains why i cant fit a normal 600m under my scope, but a micro fits easily

Troy or KAC for folders... LMT for fixed BUIS.
Link Posted: 3/10/2010 2:54:31 PM EDT
Another +one for the KAC micros here. I like having the option to adjust elevation on the rear sight. I've fucked up a few front sight posts trying to adjust them.
Link Posted: 3/10/2010 3:39:28 PM EDT
Can the KAC micros take an impact like dropping the rifle and it landing on the them? Looks like they would get bent or maybe brake off. Just wondering how they would stand up to abuse or accidents.
Link Posted: 3/10/2010 4:11:26 PM EDT
Overall - Troy
Lowest Cost - MBUS
Coolest and Lowest Profile - KAC
Link Posted: 3/10/2010 4:34:41 PM EDT
Odd that ARMS isnt getting any votes..... I have an ARMS 40-L and I like it as much as my Troy BUIS. I dont have any experience with folding front sights as I like the standard FSB. If I were however, Id go with the ARMS 40 as it keeps the same profile of a standard FSB.

Dont get me wrong, Im not saying that Troy isnt a great set, I just like my ARMS set just as much.


Like someone else posted, Im interested in the Samson sight. Spikes is selling them, so I cant imagine that they are no good. I may pick some up for my next build.

Oh, and another set for a budget, aside from the MBUS, would be this new set from ARMS. It is a metal reinforced polymer. They are only $89 for the set. Dont have experience with them, but they look like they would make a great set. ARMS 71
Link Posted: 3/10/2010 4:38:06 PM EDT
I'd go Troy if the irons will be your primary sight, something more cost effective if they are backup.
Unless of course your life depends on that backup.

I've got a set of the MBUS and I plan to use on my SBR as back-up.

I second the YHM QDS set. For $143 (IIRC) from Bright Flashlights they have been holding up very well. I like them a lot. my next purchase will be the Troy fixed set.
