Did a search and didn't come up with much. What's everyone's favorite rail and why ?
For an AR 10, I like the SWS rail...

I have the rifle version of the E1. Very solid rail, easy to install, and does everything I need from it, at a reasonable weight...
Thank you, that is a nice rail. That's probably in my top 3, along with larue and Daniel defence.
I have 2 of the rifle lngth SWS rails. Very nice, and easy to install, and solid. One is on an AR10 NM rifle and gets shot alot with a sling, and it takes the pressure, no issues. FWIW, SWS makes the rails Noveske uses. Comes with the Wrench to install it, and 2 barrel nuts so you can time to your specific rifle. And Art is super nice, we talked about 30 minutes about what I was going to do with it, what it could handle, etc. Slinging up can put as much as 70 lbs of down force on the rail. Never had an issue. The other one is on the Rhodesian AR10 Carbine
The tool and the barrel nut. All the holes allow you to align the rail up with its mounting screws to be perfectly in line with your uppers rail.The different nuts they supply have differently times holes, so you can find the one that torques up correctly for your particular rifle.
It may not look like it in the cell pics, but there is about a .030 or so gap. Even in full force, there is ZERO contact between the rail and gasblock. Its fit to that close of a tolerance.
The Rhodie
the Rhodie has an old style Armalite carbine barrel, which is of course a midlength, and the low pro gas block fits nicely under the rail with plenty of clearance. As you can also see, the rail is very light as well. ( well you can't see it, but you can see it has some lightening cuts. Not the same as a lightning cut, that would be cool in a way, but totaly different..

)Its sturdy and light. Not mucg more to ask for in a rail. Did I mention the mounting method is solid? Thats the part that impressed me the most. Especially on the NM rifle.
I personally like the PRI Carbon fiber forearm. I have not handled the 308 type yet, but got to shoot an AR15 with the Delta forearm which is triangular. It felt very solid and real comfortable in my hand. I saw a thread on snipershide.com where someone dropped their Armalite off the side of a cliff. The only thing that happened was his bipod broke and rifle got a little scratched. Forearm was good and he was stilled zeroed.
I just like the feel of the triangular shape more than anything.
SWS also does custom work if you got the money and the time. I should find out if I clear my security checks in December so I can go work in Afghanistan, and I was gonna have Mr. Art make me a triangular type rail just to have something no one else does. Every rail I have seen or fondled made by SWS has been second to none.
^^^^^^This......no question!
SWS... extremely well made. I love my Rev3 float tube.
