AR-15s: Where to find extra-long quad-rail handguards??


October 2, 2007, 12:09 AM
I'm considering a new AR build for an "ultimate varmint rifle." White Oak has a very appealing 26" heavy barrel with a gas system that is 2" longer than a regular rifle-length system (the lower pressure appeals to me as I would be suppressing the rifle). However, it would look terrible to have 2" of gas system sticking out the front of a rifle-length (12") handguard. Does anyone have a source for quad-rail handguards that are at least 14" in length?

I STRONGLY prefer the "monolithic" style quad rails, ie the kind that leave no gap between an A4 upper's top rail and the handguard's top rail.

Thanks for the help!

13.2 inches is the longest LaRue has. If your interested here is a link.

I'd swear I'd seen either Larue or Daniel Defense small run/one off's that were 14 or 15". If you contact either of those companies, I imagine they'll be able to advise you further. I know Larue is good about special orders. Don't know if DD does custom, but they are good people and wouldn't hurt to inquire.

I'm still not seeing any indicators that some of these are more than ~14" long.

I have an Olympic Arms FIRSH quad rail that is 16 inches. I forget the model number, but here is a pic on a 20inch bbl.

Where did you purchase it? Their website only lists models up to 12.5"...

Ah, some googling pulled up the F8LCR as the model number. Does that sound correct? Hopefully Oly still makes it; I see it for sale on just a couple websites but who knows if they're in stock or still made.

I really couldn't tell you the model # anymore. I think it was called the XL. I bought it about 2 yrs ago. At that time, Oly didn't have it on there website anymore. They were of no help. I ended up calling Oly dealers around the country, got sent 2 incorrect orders until I finaly ended up with the right one. It cost about $200, I remember because I normaly wouldn't spend that on an Oly product.

Occasionaly (very) I see one go used on Maybe you want to post in their wanted section.
Good luck,

BucksDC's rail looks to be Yankee Hill Machine 2 piece rifle length handguard.

i think you should have a little chat with your suppressor vendor of choice to make sure they're cool with a 26" barrel. they may recommend you cut back to a 20" or so

The longer the barrel, the quieter the can, since the muzzle pressure is lower. K baffles do tend to be a shade better with high pressure, but even with 26" the pressure will be plenty high to make efficient use of K baffles, and the extra length will make up for any loss of baffle efficiency. Plus it'll be a custom can of my own design. Suppressors increase back pressure so it'll probably cycle like an unsuppressed Rifle-length gas system.
