AR handguard help

[Mike D]

I finally got some parts in for my current AR project. Now I am looking for a specific hand rail but I'm not sure they even make it. I want a hand guard similar to this one:



Only problem I see is that this one is made for an M4 carbine and mine is an 18" SPR with a mid-length gas system.

I am wanting to accomplish some thing like this:





While using this type of gas block/flip up sight system (they make a model without the swivel and bayonet lug):



So, any suggestions?

Thanks Jamie, but they only have that one for the carbine length rifles. I need one for a mid length. I found one at Daniel Defense but HOLY COW they are proud of that puppy!

I would check with LeRue and Noveske. Both make their own from scratch....

Mike,

Have you checked out the Vltor?? This is what I plan to use for my next build.

That hand guard looks like a PRI, if I'm not mistaken. If you want something like that, then I'd suggest getting that one. However, since you have a gas block with the rail over the top of it, then I would suggest a midlength Troy MDF or a MI Midlength (9") so it goes right up to the gas block, but doesn't cover it up, since it's a flip up sight.

Samson Star has one:

Front-site Base w/o Bayo lug:


Front-site base with bayo lug:


Daniel Defense has a 12" Rail with Front Sight Base:

The Daniel Defense 12.0 FSPM Free Float Rail System features a cut in the front of the top rail to accommodate the front sight post and gas block of a mid-length AR15 gas system, while at the same time, providing much needed additional rail space along the sides and bottom rails.

Yeah Paul I looked at the Vltor, they didn't have what I was looking for.

If you are talking about the ones in my original pictures, those are a YHM fore end and FSB. They only offer that series in the carbine length though.

I saw the DD one you posted and regrettably that one is out of the budget at over $350.

MIke look at Wilson Combat....... I am really looking into the same design myself..... machined down with small rails on the sides and full rails on top and bottom.

I feel your pain. The most economical way to do it, and I'm in the same boat, is the Troy MDF *Modular* which is free float. The 9 will go right up to the gas block, and will allow your flip up to work effectively. Honestly, my choice is the low profile, and a rail that will go over it altogether, save that money and buy a "cheaper" front sight, like the Troy or Magpul. In fact, this is what I am talking about with the 9" and the low profile.

That was the route I had originally planned. I planned on a low profile gas block and a rifle length rail. This would totally cover the gas block and have lots of rail space. Budget wise that is what I am going to have to do unless somebody hurries up and buys my upper from the classifieds.

Actually I have already bought the gas block. I went with the Vltor GB-2CS and am still debating on the handrail. I will probably just go with a YHM diamond series like I had originally planned.

I still have to buy a couple of Larue optics mounts as well.

Mike I'm pretty sure that there is not a company out there that makes a railed gas block that install's even with the rail. The gas blocks are almost always about a 1/16 shorter and do not match up..

You can run pretty much do the same thing but will have to adjust a bit in your configuration. Go with a Larue Low profile gas block and then buy the handguard of your choice then install a Troy FSB....

On my Colt Im running something close but using a carbine gas system with e Larue low profile gas block with a 10 inch Larue rail system..with a Troy FSB...

IF I remember right the Larue 12 inch railed handguard is around 299.00, Larue low profile gas block is around 69.00 and a troy FSB will be around 120.00

Keep a eye out on the EE of at ARFCOM I picked up a green CTR for 50.00 the other day that was new in the box...

Mike,

Doesn't the Knights URX II have a flush flip up site?? From the pics I've seen, it almost appears as if part of the rail actually turns into the front site.

[Tuffbroadhead]

Here is a picture of the urxII it is one complete unit...

[Mike D]

Hmmm. Pretty slick.
