How are the magpul mbus front anf rear sights? I like their light weight and low price. Do they work well enough as my backup sights?

I think they are junk IMO. Get what you pay for.. And be careful and don't buy the airworthy ones that don't work for like half price like everyone else on here did thinking they found a deal a few years ago.

Yep, complete junk....8,000 rounds and 5 carbine classes later, they're still working fine as backups for me. UMMV.

They are good and tough little sights. Good value sights.

What I don't like about the front sight is that the protective "ears" are very thick. I suppose that's because they have to be, being made of plastic. But it makes for a crowded sight picture when trying to line up the rear aperture with the front post while also trying to find the target.

They're fine for a backup to optics but I wouldn't use them as my primary sights.

I wouldnt use folding sights as a primary period.

My only complaint and I have no Idea why they have never given me trouble is that the rear Peep is made out of plastic If It was made out of metal like the front post I would trust them 100%
An oh yeah Because they are plastic dont mount them on a railed gas block FS will Melt

these sights are not worth the trouble. Look in the marketplace to get a good deal on a better set.

I have them and have had no problems. I only used mine for a bit until I bought a scope and now they aren't even on my gun, but I liked them when I used them.

Agreed. They're junk. If your life might depend on them, spend a little more on metal.

They are better than nothing. They aren't great...if you are looking for battle (backup sights) there are better options. I like Troy folders

Sure looks like crap.

Honestly, the only bad thing I've heard bout them is that some of the earlier production ones had lower quality polymer and could melt during high round sessions. Course it still applies to the newer ones but its a little more durable. That said, I run Troy on mine.

Its pure crap, I took mine off on ar-15 and put it on another and it held zero. wtf, why would it hold zero? I was so pissed it held zero going from one gun to another.

Hey folks they're back up sights! Alternate, the scope broke, your friends scope broke, you dropped your rifle on it's head. BACK UPS!

I hate the rear peep. It's crappy to look through when using it with a FSB. They aren't that bad. They do exactly what they are supposed to be "back up sights" and they do that fine.

If you wanted to use them as a primary, I would not reccomend them at all.

They are a good cheap buy if you have a high quality optic that probably won't fail you, and you still want that extra insurance that you can still aim if your optic did infact break.

Mine have served me OK but the sight picture sucks. However, I don't use them much anymore after getting an EOTech.

This doesn't make since to me.. Why would you buy anything on your rifle you wouldn't trust for primary use?

If your optic goes down that is now your primary.. In other words you guys mean they are ok for a fashion statement.

Picking folding sights as a primary is a fashion statement.
You got it backwards.

I use 'em as primary sights on my 9mm AR that I use for plinking, but on my .223/5.56 ARs, I use the LMT tactical rear sight as my primary iron sight.

I think they make good backup sights. I have an eotech w/ an eotech Magnifer. I don't see why I would spend $200+ for Troy sights as a backup. If SHTF and my eotech fails and my backup mbus fails, then the AK will come out to play.

MBUS = (Magpul Back-Up Sight)

"Back-Up Sight" are the operative terms that apply and for which they do a fine job. I have no complaints with mine because their performance and price point have allowed me to buy more ammo, and do more shooting.

I dont mind them one bit, the only thing I would change is to maybe shave down the front outer peace of the front sight mainly because its kinda bulky but works fine. Got them installed on my Dissipator upper and does its job.

They are good enough as back up, but my SU top is too short for them.
I only wish that my SU has a longer top rail to install a pair of back up sights.

they should only be used as back ups.

I have both types.

The metal ones have a nicer feel. I love the sight picture of the Troy sights, and MI is nice too. I recently got to play with a KAC 200-600M (USMC) flip sight- that's a neat little thing too, though it feels more delicate than the rest.

That said, the Magpul ones work just fine. They don't feel as nice or look as fancy, but I see no reason they would fail.
The 2nd Gen magpul is much better- 1st gen might be a bit more durable (thicker), but the easily adjustable front sight of the Gen 2 is well worth the upgrade.

I respect your right to have an opinion.

However, that doesn't mean your opinion is right. In fact, it's wrong, and completely invalid.

Drop tests on Magpul iron sights compared to metal sights by major manufacturers prove that one drop on aluminum sights WILL break or bend them. Multiple drops on MBUS sights do no damage and did not throw off point of aim.

And be careful and don't buy the airworthy ones that don't work for like half price like everyone else on here did thinking they found a deal a few years ago.

Yeah - there's some exact airsoft copies that are incredibly low quality, and aren't worth buying. Unless you use them on airsoft guns, anyway.

They are an awesome budget BUIS. The price vs durability trade compared to Troy is great, they get the job done.

I have them and they were very easy to zero. I really want to know how many of you are taking your rifles into battle or entrusting your life with them. These arguments never stop. Sure I want a set of Troys because they of course will be bulletproof. But, I am OK with spending half the money for BACK UP SIGHTS for when or if the battery dies on my SPARC. I trust my MBUS's. Maybe you should try a set first.

They work. For a backup sight on the cheap, they do the job just fine. Yes, there are much nicer ones but I personally fail to see any flaws with them so far considering the price. The protective ears are a little fat but hardly a deal breaker... besides they are there as backup. If buying the mbuis frees up 50-100 bucks more so I can get a higher quality main optic(which I will be using 99% of the time), I don't see a problem there.

cpatbay,

Those sight are enough for a back-up sight for you. Allot of people bash them cuz there made of plastic but I never shot my rifles enough to experience any heat related issues. Besides that do you really think your going into combat situation???? Believe me dude buy them and use the saved money for other things you want.

I have no complaint. Sure, I would get Troy over MBUS if they cost nearly the same. But since they don't, they are fine for me. Rings the gong all day long @ 100 yds. Have the front sight on a gas block rail and no sign of melting.

Lifeon2whls
09-14-2012, 8:37 PM
My MP15 Sport came with the MBUS rear and I thought it was fine. Would trust my life to it if needed. I zero'd the rifle at 50 and then 100 yds and got some decent groups with little effort. I saw no reason why these sights would be considered "crap" or bad in anyway. I wouldn't use them in competition but that's not what they are designed for...they are made to get you on target and fold down when not needed...they do that perfectly.

It's pretty obvious that the people saying Magpuls sights are junk don't have a clue what they are talking about. Go ahead and smash a troy on the ground and try to operate it. If it does flip up, piont if impact is going to shift almost to the point of useless. Do the same thing to the magpul sight and your POI may change 1 moa. {Pretty crappy for a ****ty backup sight right?}

These plastic versus aluminum arguments remind me of the same arguments for and against the Ruger 10/22 plastic trigger guard. Some people are appalled at the idea of cheap plastic trigger guards. But if you watch this test you see they are actually more durable. (skip forward in video to 1:27).

biMkNYWAzIk#t=88s

I would imagine if you were taking your AR on a hunt in rocky terrain you would have a higher chance of accidentally dropping your rifle. If your scope got damaged in the process having back up sights that are impact resistant would enable you to keep going rather than giving up and going home.

I have a set and like them well enough for plinking. The apertures and adjustments aren't as fine as I would like on an irons sight that I'd use 100% of the time though.

edit: beware the fake magpul crap only buy from reputable online or retail vendors. Gun show sales I wouldn't chance it unless it was a seller I knew.

which is fine with me since i don't plan on adding any optics so fold down wasn't needed.

Yup that's why I dont swear by a glock and a crap ton of magpul furnature/pmags :rolleyes:

Has nothing to do with them being polymer..

But I've learned better than to argue on the internet, wont get anywhere and will be a different outcome in 2 weeks . And the only ones going to show up for this are obviously going to be the MBUS owners.

I run them on my class gun and they serve a purpose just fine. If you're in a position where your primary optic fails and outside the range of your secondary, keep shooting! You can use your EOTech/AimPoint as a big ghost ring.

Yep, the newer ones I believe are all now shipping with MBUS.

That said, my scope went to crap today at the range. Old scope and I started shooting all over the place. Next thing I knew, the cross hairs were an X and the scope hadnt moved. Popped off the scope, flipped up the MBUS and finished out the day...and did pretty well at 100 yards

who else would show up in a thread that is asking about the magpul mbus? non-owners who have no experience with the product and trying to pass of info they heard from their friend's brother's cousin's dad's second sister's grandpa?
