is this rail made of aluminum or polymer?

defin. not polymer/hardened aluminum but can be purchased cheaper elsewhere as I found out after I bought it here.

I am almost positive it's aluminum. But I do not have it in my hand to confirm. It is very precisely made and well coated black. It also comes with a separate steel washer to sit flush against the barrel. I sent a few hundred rounds down range through it and it does not come loose. Just remember this is for the thicker bull barrel for smooth, flush look (or it will extend outside the diameter of the regular barrel).

You need steel rings AND a steel scope rail. You dont want any aluminum. It starts to shear with high recoil loads. I ruined an aluminum base in 10 shots on my .500 handi rifle, which is similar in recoil to a hot 12 gauge slug.

Best I can tell aluminum. At least the shaft that goes into the rivet gun is aluminum. Don't know about the expanding part.

It is metal and lightweight. So I assume it is aluminum. But I'm not certain, sorry.

T-6 Aluminium. I use nothing but their tactical scope bases. They also make very high quality rings

The one that I bought was 1 1/4" long. Also, the bottom piece is aluminum and the thin top piece is steel, not aluminum as advertised. I bought mine for a bipod mount and it worked perfectly, stayed on tight. I decided to go with a quad rail and took it off. I'll send you the one I have for free if you can find a way to get me your address without pissing off Amazon.

Metal; the second rail slips so I've had to use duct tape to ensure a good grip with the clamps; otherwise I like the racks

The rails are made of a high density plastic type material. They can be cut to any length. I have cut one of the rails in half for my personal installation.

It will fit on a picatinny rail and yes, it is made out of metal. I have mine mounted on a rifle and was worried about the recoil, but it has stayed true. I would buy it again without hesitation.

Appear to be high grade aluminum. I have 12 sets of these one set on each rifle and two of the rifles are 300 winmags. Have not had any problem with them. The two main features that I look for are: 1.) four screw lock down on the scope and 2.) lock down on the rings to the rail being nuts not screws. I have installed these as said on 12 of my rifles ranging from 17HMR to 300 Winmags. Hope this answers your question.

They are made of metal and easily to break during installation. The half were the screw tightens up on the rail cracked making it useless.

I'm not sure, but looks like gold aluminum. Works great and was a very good add-on for the price.

So far the answers I see are partially right. The main parts are aluminum, while most of the hardware type parts (the front sight post, the screw, springs and pins) are steel. I just checked with a magnet, which slid towards portions of the sight where a steel part passes through.

aluminum rails with a light metal connector. I have used various profile bars and found these to be good for the cost. One downside is the handlebars I have are sloped at the stem clamp site and found the bars did slide if not extremely tightened.
