West Lake Keymod Picatinny Rail Sections, 3-Slot 7-Slot 11-Slot, Solid Aluminum Single Dual Keymod MLOCK Compatible Multi-Functional Rails (Black)

I didn't expect much for the price, however, I was very surprised by the quality of the extrusion and the weight. I grabbed a magnet just to see if the rails were steel when I got them because they were heavy enough to make me think they weren't aluminium.SO far hey are as durable as any higher priced ones I've purchased and are actually better finished.

Excellent product and price, superfast shipping, AAA+++

These are made cheaply and it shows but I don’t need much to hold a 5 oz laser to a rail. These are perfectly adequate for ancillary accessories you may want to stick onto an AR.They are designed well. The pass through for a strap is a good idea.

This has went past my expectations the packaging included well made very sturdy arrived faster then I expected I will be buying more of these if you want my opinion spend the money, you are getting a high quality item for little money

These rails are perfect in every way for me. Excellent quality, heavy-duty but not heavy in weight. Now the part about these fitting M-lock & key mod. That's possible because there are 2 styles of nuts. Don't spend 10 minutes trying to attach these rails with the wrong nuts, like I did. The round nuts are for key-mod and the oval shaped nuts are for M-lock.

The overall quality and design are not bad. They certainly look nice, and I can't argue with the price. However, I purchased these with the intent to attach a quality QD sling and quickly found that the QD point on the shorter rail section is not built to specs. My QD sling swivel would not lock in place and would pop out at with the slightest amount of tension.

The only thing I dislike is that I didn't buy more of them! Smooth edges, no weird machining marks like the cheaper brands. Strap pass-under on one of the pieces is nice to have, the raised loop is beneficial as well. Bars also have raised notches on the back to prevent slipping when attached - recoil is a cruel mistress.

I was surprised when I seen the quality. As I was mounting them on the hand guard They fit perfectly haven’t had any issues with them coming loose or sliding. Definitely recommend.
