Question for the AR Guys

[dubs chops]

Hey guys, I have seen a coupe of AR's that the upper rail goes all the way from the start of the upper receive to the end of the foregrip without stoping where most have the delta rings. WHat is needed to do this? Is it a fore end you can use or a whole other gun MFG, that dont use the delta rings? like the top one here

I'm not sure I'm understanding the question right, but it looks like that one is a monolithic (sp?) upper where the entire thing is machined from one piece. Here's another version from LMT:

The one in the pic looks to slide over the flat top. There are a few different ways it's done.

Oh OK, I didn't know the whole upper was one piece, How do the slide over ones work? Anyone have a link I could check out?

Several after market rail manufacturers offer free float rails that give the monolithic look. Daniel Defense, KAC, YHM, Midwest Industries and about 10 others.

The one you linked to is a POF Predator rail. Like 264 said, there are about a million different ones out there.

Let us not forget VLTOR...you don't even have to replace or uninstall the barrel nut / delta ring assembly.

ETA: FWIW, I still don't recommend placing optics on anything but the flat top upper itself.

+1 for VLTOR... I have one of the first one evr made, and I love it. I have sold a bunch of them also and nodody have ever said a bad word. I will put one on the 9mm carbine as well, as the weight is almost nothing.

Also you add a rail only where you want one, and it comes with 6 rails.

Daniel Defense Omega is the easiest/best one.

Daniel Defense Omega is the easiest/best one.

With the Daniel Defense Lite being the coolest looking
