If they can keep the weight down I might have to ditch my DD rails for these.

Yes it's quite nice.

Bill Geissele is a mechanical genius, and wouldn't be coming out with a rail system if it was significantly different than the current players in that market like DD, Troy, Centurion, Larue, etc.

I think the larger barrel nut is a very nice feature that will allow for more contact area with the rail, and by extension this will yield more rigidity, and should also help with heat dissipation.

I have good faith in anything Bill makes, but I don't know that I'd be ditching anything for anything.

But then I'm still using my DD M4 rail on the same gun for the last 5+ years.

From the videos of the Geissele handguard he mentions not having to line up the gas tube notches, which in and of itself is great.

The fact that the Geissele rail got a mil. contract over other more well known rail manufacturers like KAC or DD says a lot. If anyone who is at SHOT gets a chance to handle these let us know.

The one thing I haven't seen about this rail is anti-rotation. He(Bill G.) mentioned the production version will have teeth that engage the barrel nut, but I don't see that as an anti-rotation measure.

Is the bottom rail removable?

I see the top rail is not taken to the extreme end which is also a negative.

What did they get a contract for?

With that in mind the Daniel Defense rail is totally drop in, and is so low profile and light it makes the normally boat-anchor-heavy 416 feel like a modern featherweight SBR.

ETA these comments are in regards to the 416 rail!

The 416 rail uses the standard HK barrel nut. The M4 rail uses the proprietary barrel nut
