I cant say for sure as I have never handled one of the FIRSH forends, but by the looks of it from Olys' website, the FIRSH w/out panels looks fatter than the LaRue with a set of TangoDown panels mounted.

What would some of you recomend for a two-piece rifle handguard? I'm thinking about First Samco, are they any good?

I would say NO. Especially if you plan on mounting anything on the rails. Unlike their ads illustrate, I would never mount a optical sight on their handguards rails. The only thing that would be acceptable to mount on those would be a light...Maybe. If money is your main concern, I would suggest going for a YHM.

My main concern is getting a good railed handguard. I don't need the absolute best, but I would like a fairly good one. Thanks for your help.

I would say go with the Larue 12.0 then. Not cheap, but reasonably priced for what you get.

Can we get an update with the weight of the LaRue and Troy tubes???

Grant, you there?
Link Posted: 3/5/2005 8:06:03 PM EST
Could someone please add the LaRue weights to that chart?

7.0 - 11.5oz
9.0 - 13.2oz
12.0 - 16.5oz

For comparison here's DD

7.0 - 8.5oz
9.0 - 10.5oz
12.0 - 13.1oz

So I don't get it, if the LaRue rail is better, than why does a DD 9.0 weight less than a LaRue 7.0? Where does that extra weight come from on the LaRue's or should I say go on the DD? I mean 3.0oz's on the 7.0's is a huge difference!

I recently tried installing a Yankee Hill Manufacturing 2-piece rail fore end on my Colt M4 upper (M4 upper receiver, M4 14.5" barrel).  The only non-Colt part is a LaFrance gas tube system.  The YHM top rail assembly does not clear the sheet metal tabs on the front handguard mount - looks like the rail was not machined to fit.  My understanding was the YHM parts were mil-spec.  

Anyone else had this problem?  Looks like I'm going to have to mill it to fit.  Any thoughts?

The extra weight is likely from the LaRues steel barrel nut vs. DD's aluminum barrel nut.

Yep. They are designed to be tight.  I had a helluva time trying to fit mine, and I called YHM about it. Actually, I posted just like you, and a YHM rep IM'ed me through the board to call him. I sent the upper to them, and they installed it for me.

Has anyone here tried the Surefire M73 rails that are on the D.E.A carbines?

Are they steady enough to mount a red dot sight on and not move around?

How are these installed?

Are they one piece, two piece, do they require the barrel or front sight to be removed for installation?

Thanks for any help on this in advance.
Link Posted: 4/1/2005 11:43:35 PM EST
Problem resolved on the YHM foreend.  We machined down the front so that it would fit.  Very snug and rock solid.  My Surefire M900A foregrip doesn't have any discernible play.  Tango Down rail covers slipped right on and snapped in.

Paid only $100.00 for the YHM foreend, and it seems like a true bargain considering what folks are asking for a KAC RAS these days.
Link Posted: 4/2/2005 1:55:21 PM EST
I had the Surefire M73 handguards on my carbine. They were very solid, I would think an optic should be fine. They are two piece and easy to install. I got rid of them only because I sold the upper and got a mid-length. I'm going to put a FF rail on it. Still haven't decided whether to use the YHM or go up to the Larue.

I just bought an Olympic  K3BM4A3TC with the firsh handguards. They are fat and seem fatter than any other AR-15 free flaoted that I have held befor. They get even wider when you put the rail covers on. But if you have large hands they actually feel more comfortable.

I want to get a FF rail for my colt 6450 to mount my Trijicon reflex, but I don't know which one to get.  My reflex is in an A.R.M.S. #15 mount.  Will it sit high enough to co-witness the sights.  Which rail would be best?

I have a set of the new  MI 2-piece  4-rail hand guards  from Bravo Co. and they are really great . they fit tight. The best thing i like it that they are marked like the T-marked uppers they have  T numbers  on top R numbres on the right side and L on left side and B on the bottom rails. All for $120.00 great for the price i think.

Sorry if this has been posted before.
Does anyone know what is the absolute lightest option available for a flat top w/ free floated tube. (No rails necessary) I have been looking at Houges and Bushmasters V-Match. I need a 16-20" barell with a milled front sight, am considering fluted for less weight. Also need the free float. Any suggestions?
Thank you

I didn't see anyone list the Brugger & Thomet Quad Rails.  These are not free floating, but like the KAC RAS.  These are the handguards that will most likely be used by The Netherlands for their mid-life upgrade program for the Diemaco C7 and C8 rifles.

Weight for full length = 512 grams, or 18.07 ounces.
Weight for carbine length = 305 grams, or 10.76 ounces.

I like everything about it EXCEPT the weight.  It weighs more than the YHM and the KAC M5 .

It's installed weight is even more than my MFR-R!

Does yours have a raised rail on the upper receiver?  That would explain why ARMs would not work.

As far as anything else, I think it would be fine. My carbon M4 has standard handgaurds and I'm sure I could replace them with anything I wanted to (mine has a perm attached flashhider so most lightweight FF tubes are out of the running without a lot of work, and I don't want to add a lot of weight with the other HGs, so I'm just sticking to the original).

If you really wanted to put a railed handguard on yours I don't think you are going to run into any real carbon specific problems. The only ones that I am aware of are the raised rail (no ARMs SIRs) and that you have to be more careful with the threads on the upper when installing the barrel and nut.

Personally I would keep the Carbon 15. I love most everything about mine. My only gripe would be the upper receiver, and don't really care for the raised rail and sometimes you need to extend the feed ramps for reliable feeding of all ammo types. If I ever get fed up with my carbon upper or it starts having problems I'm just going to replace it with an aluminum flattop upper.
