Guys,

Since I've finally been able to purchase the barrel I had been searching for, it seems my YHM15 rifle project is finally nearing completion. For those who are not familiar with YHM, I am building a Black Diamond Rifle which will have the following components:

YHM Upper/Lower Receiver
YHM BCG
Magpul MOE Buttstock
YHM 12.5" Diamond Series Rifle (4 rail) Floating Handguard/Forearm
YHM 20" Fluted/Threaded Barrel with 1:7 twist rate
Harris Bi-pod
YHM Phantom Comp/Flash Suppressor
EoTech MPO III

*BUIS??? Here's where I need your help. I've researched other brands and I've decided to stick with YHM. I am not sure whether to go with same plane plane flip up sights or flip up sights/gas block combo? Here's a couple links to show you the options.
Q.D.S. Same Plane Sight System. http://yhm.net/index.php?main_page=product_info&cPath=2_3&products_id=4
Front Flip Sight Tower (w/ gas block) with Bottom Rail http://yhm.net/index.php?main_page=product_info&cPath=2_3&products_id=11

This one is the way to go, IMO: Front Flip Sight Tower (w/ gas block) with Bottom Rail

Looks cool and it's functional, what more could you want? :)

Looks like it's gonna be a badazz rifle either way!

is there an advantage using a gas block front sight vs. just using rail'ed front sight? other than the gas block based front sight will be farther forward.

OP.. just make sure that front sight is for a gas block mount. i put a normal rail mounted front sight and had that post wayy high and ran out of adjustment. until the good 'ol' cgn members told me i should've had a front sight for gas block. LOL :)

The only advantage is it's an integral part of the gun - less likely to fall off AND like you mentioned, it *is* a touch farther forward (also, I personally like the looks.)

He won't have to worry about the front sight on the gas block mount, since the sight is *part of* the gas block. ;)

I agree, for some silly reason I do prefer the looks of the flip sight tower with the integrated gas block. I suppose the FSB is such an iconic image that when I think of an M-16/AR-15 I automatically think of a carry handle and FSB. Technically, this is not an FSB, but it does have that appearance somewhat when deployed.

Thanks for the positive feedback, I appreciate that. Also, YHM makes the same sight/gas block combo with a sling attachment and bayonet lug. There are several varieties to choose from. The one in the picture I thought would be good if I decided I ever wanted to mount a tac-light on the lower rail. Options...options...options. Oh what to do? What to do?

Look at Troy sights and look at the DI optic. The dimond back sight. I got one and pick up the sights so fast and easy. And it looks bad as* imo

You know, I thought about that and I contacted YHM and they told me that I would need to buy a riser in order to make the gas block rail on equal plane with the top rail, assuming I wanted to go that direction. So in that scenario I would have same plane sights, with the only difference being that the front sight would be attached to the gas block and not the hand guard rail. So many damn choices! Sheesh. :facepalm:

Buy a gas block that is the same height as the receiver rail and then you can go with the rail mounted flip ups if you like. This one for example:

Otherwise just go with the YHM gas block/flip sight combo. My rule of thumb is to always put the front sight out as far as possible.

^^^^ I would do this as well

I am not a big fan of YHM flip up sight/gas block.

Nice looking build BTW
