Well made, perfect length for my laser/light setup
This works great on an M-LOK compatible hand guard. This one has 7 slots and works for various 1913 picatinny rail mounted accessories. It is made of Mil-Spec anodized aluminum. The length is 3.3 inches. The distance between the screws is approximately 2.3 inches on center, so take in consideration of the location for mounting. I used it for a laser/light setup that I wanted to be able to mount and remove easily. It came with all hardware including nuts and bolts for the hand guard. It feels sturdy, with no wobble. It is made by Magpul so it is good quality. I did not have any difficulty with the installation.

Magpul is the best
This Magpul rail adapter is rock-solid once installed. The machining is precise with clean edges and perfect M-LOK alignment - no wobble or play when properly mounted. The aluminum construction feels substantial without adding unnecessary weight, and the anodized finish has proven durable against wear. Installation is straightforward if you follow the included torque specs. The T-nuts engage positively with a satisfying click, and the anti-rotation tabs keep everything exactly where it should be. The rail slots are properly sized to MIL-STD-1913 specifications, so accessories mount without any fitment issues. Important installation tip: clean the mounting surface thoroughly and use a torque wrench to avoid over-tightening. The included hardware is high quality, but you'll want to use a tiny bit of blue Loctite if you're planning heavy use. One note: while compact, double-check the length you need for your specific application - the rail section might be longer than necessary for some setups. The low-profile design keeps accessories close to the mounting surface, which is exactly what you want for most applications.

Quality that takes a beating
It looks like Amazon ran my package over half a dozen times before chucking it onto my porch. Thankfully, Magpul makes good stuff, so the rail is only slightly scuffed. The rail isnt bent at all despite the significant force put on it. Disappointed (as usual) with Amazon, quite happy with this product.

GREAT BUY. AA+
MAGPIL Makes excellent products all around, I have never been disappointed in any Magpul products, and these aluminum rails are no different, they have the polymer and aluminum rails and for most things the polymer ones work great, but for other things the aluminum rails are light and work terrific, reasonable price point. they fit perfect, the bolts are a little bigger (and come with threadlock) than most that hold the Mlok or keymod nuts. for a more solid and durable hold.
