Single Picatinny Aluminum Accessory Rail Set with T-Nuts & Screws, Wrench- Squared Corner- Aluminum

Just as described, and great quality!

Love this put them on my arp and ar-15 no problem at all and easy to install

They are as advertised working great

I'm modifying one or more of these, so my opinion is likely different than others. As someone else stated, these don't look like aluminum, or almost like pot metal, but I think it's because of the paint. I ground into one and they are solid aluminum. They could even polish up if one so desired.I just don't like the fitting "nubs" on the bottom, which is probably desirable for some uses, but not for mine. Otherwise, 5 stars.

They seem to be good quality considering the price

One rail section was mounted to an AR10 upper, and it fit the MLOK slot. Before mounting, the slot was stressed with pilars to force a twist, but the rail did not twist. An Atlas bipod, prev mounted to a Magpul rail, was attached, and no adjustment was necessary. At the range, performance was satisfactory. I would buy the product again.

This riser is just right for mounting an Ecotech Holographic sight on an AR platform rifle. Easy to install and use is great, solid built piece.

Added to my AR and everything so far is great.
