YHM flip up gas block sight

no just adding to my wish list of “toys” to get.

If you are still considering the YHM flip up FSB, take a close look at the design. It is 3 separate pieces for the gas block portion, held together by 4 screws. It relies only on clamping force to stay put. If those screws come loose your rifle won’t be working right anymore. It isn’t a confidence inspiring design.

Can’t say were not trying.
It really does remind me of Monty Python’s dead parrot.
As I was saying…:dirol:

No its why people don’t respond to questions the way they used to.

i like the KISS you know keep it simple stupid

I see where you are coming from .:smiley: Best way to go.

have you looked into a troy 2 piece …MRF (if i remember right) quad rail? You wouldn’t have to remove the gas block to put it on. So it’s lots easier to install than a freefloat.
For short ranges, you wouldn’t see benefits from a FF rail anyway.

Check them out. Might be right up your alley.

Way too many documented problems with them for those sights to be taken seriously.

totenkopf- Yes, I believe so.

Check this place out: http://www.ar15.com/index.html They might know about what you’re asking. lots of rangers there… And seals, and delta, and seal team 6, and chuck Norris, and other people who are trying to be “different”…:suicide:

I understand the want for something different than every other AR out there, but keep this in mind: Some configurations are very common because they are optimal for the roles that they fill.

Mr Blasty I know what your saying I,ve run into more Rangers since I got out then were in. I,m not trying to be different and I know that some AR,s are build by arm chair commando,s too. I was thinking of building a 3gun style but cant really decide on that yet… funds more then anything. I,m not going to put a YHM rail on I know there are WAY better … notice I didn’t say COOLER ones out there … Been doing my homework on what I want I know the good and bad parts in AR but trying not to go over board on cost if I had unlimited funds boys that would be different. But when you live n a Disabled vets pay well you have to make do. I,ll probably just upgrade the rail I have now and stay with the FSB. I have now the FSB does interrupt the red dot when "sighting through but thats not the reason I was doing an upgrade. I have a 2piece rail now and when shooting at night the rail moves when I push my light on with my thumb it makes the sight picture move out of zero when shooting. that’s why I was thinking one piece. Not going to say more about ARF.com Mr Blasty just know what you mean there! Ok guys I thing we,e run this horse into the ground … hope your ARnever runs out of “pointy” things when the SHTF. RLTW 2nd Batt 75th Inf

Seriously.
Clean up your posts.
They are very difficult to follow.

Also, if you have your optics mounted on your non-freefloat railed forearm, how exactly do you hold a zero?
It should be mounted on a flat top upper receiver.

There are mounts for your Aimpoint that will give you a lower 1/3 co-witness.
Meaning, that your front sight base will only be in the lower 1/3 of your sight picture when looking through your optics.
When you flip up your rear sight your dot will move to a absolute co-witness.
Meaning, the red dot will be positioned on top of the front sight post.

EMTS, do yourself a favor. Don’t but it. If you did, sell it or throw it away.

I say this because I HAD one, and it sucked from alpha to omega. I got sick of it quickly, and shitcanned it.

I respect many of the members opinions about subjects that are posted in this AR forum. But I really have to chime in with my 2 cents. First off YHM is not crap. They were one of the first manufacturers of rail systems in the now heavily saturated AR market. Do they compare to the likes of a company like Larue Tactical, no.

They are functional, can take abuse, and just plain old work without breaking the bank. To say the YHM front gas block/sight is junk is pure nonsense. To say it can’t be mounted firmly enough for rigorous use is pure hyperbole, or just simple stupidity (you choose). It might take a competent gunsmith to make certain it is mounted properly. The free float rail system works as intended, it has never moved or failed in any way, just like the gas block/front sight. Last but not least, the suppressor host. There was a time that the Phantom ruled the market, it isn’t the newest of designs but it works. YHM may not be the newest Gucci gear on the market, but it’s a far cry from the junk some of you posted in this thread.

I have one particular M4 type platform that has three pieces of YHM gear attached to it since 2006. This AR has seen 8000 rounds, which is probably 7000 more rounds than most AR’s in the picture thread. It is good enough for me, maybe some of you* need to get off of the if it ain’t so an so, it’s crap, you’re wasting your money. The continued bandwagon jumping disgusts me, we are one of many firearm’s communities that constantly eat our own. M4C thrives to be better than TOS’s, but it is quickly moving in that direction.

This was my first ground up build and every component will stay on it as I am happy with the setup. So now you can flame me about the B.A.D., Grippod, and KNS. EMT, you caved under the pressure of a few zealous Tier 1 only for me types. If you’re not certain about something research, research, then post the questions. My builds now consist of BCM, Spikes, LT and several other companies. You learn as you go, but it doesn’t hurt to try things that you like either. I love my CRAP build. I agree that you need work on your posting skills, they are almost incomprehensible. Are you sure you’re a former Ranger. Where were you stationed?

  • applies to 2-3 people.



Sw shooter : at some part I did give in but only to the end of not taking this to far. yes I,ve used YHM and installed YHM on my buddies AR and it looks great and function great. most of these guys out there didnt get what I was trying to say yes my nomenclature might not have been the greatest but one person got what I was trying to say. yes I was in rangers class 42 jump school at Benning right next to the OCS training center in the 70,s then dragon school for anti tank then to camp darby and the infamuos darby queen when the first thing you saw when you walked in camp …was abandon hope all ye who enter here in Black and yellow letters. so that alone should tell you this aint no arm chair commando and that alone should tell you I was there . oh by the way was the Quonset hut still there when you went through?

I was going to ask about the GG&G Bolt on Flip Up Mount
http://www.gggaz.com/bolt-on-flip-up-front-sight-gas-block-system.html

If this GG&G is also “junk” like others have said the YHM is?
If so… what would you suggest as a good flip up front sight/gas block to replace the stock one on a S&W M&P15??

In advance THANK YOU for sharing your knowledge.
(I’ve tried searching and reading around)
But thought i would “piggy back” on this thread in hopes to
NOT steal anything from the O.P. rather just add to this thread not just for me but others in the future searching YHM, GG&G flip up front sights so they might find this and learn.

First off, I am not trying to be a jerk, but what is the love for the flip up/ clamp on front? I don’t just mean you. I am not singling anyone out here. Don’t get me wrong, GG&G is good, expensive kit. But I just don’t get it. You are taking away the security of taper pins and adding a sling mount to pull on the already less reliable clamped on front sight.
This is why there are 1000 flavors of ice cream, but a riser on your RDS will get you over top of your FSP or a rail with a flip up front sight would be much more reliable.

EDITED

The sling mount was the first thing to come off of mine. Really no use for the bayo lug either, but it can stay.

I’m really curious about what you wanted to say Stick, you are very well versed with the AR platform and I respect your opinion.

2/75th was out of Ft. Lewis when I was there.

I have a RDS with riser for lower 1/3 BUT i also have a few hunting scopes in my safe i wouldn’t mind popping on but the one i tried the
stock pinned sight is just right there in the middle.

I like to co-witness my RDS but wouldn’t mind the versatility of being able to fold it down out of the way.

For now it’s just something i have been thinking about and by no means set in stone. (plus i found a deal on a USED but never mounted one of these with the Trijicon tritium front sight post installed)

That’s why i’m wondering if these are any good or if there are known “issues” and if there is who makes a reasonable priced one
that they have used and would use again in another build.

Thanks.

SW Shooter,

I am glad that you are happy with your YHM rail and sights. It doesn’t change the fact that they are shit. Their rails are known to be inconsistent, and their technology is old.

Their sights are fragile and anyone who considers them for serious use should use the SEARCH button.

EMTSmokeater13,

I suggest that you start using proper English and clean up your posts lest people decide that you are simply a troll and don’t take you seriously.

Also, every single Ranger that I know would be kicking someone in their balls if they didn’t capitalize Ranger. It’s kind of like saying “I was a seal” which will is also a good way to get called out.

As I mentioned before. Break your posts up a little and make them coherent to others.
