LONSEL 90° Picatinny Offset Rail Mount, 3 4 5 Slots 90 Degree Offset Picatinny Rail Mounts Aluminum Low Profile Adapter for Flashlight Laser Sight Optics

It worked well for my uses. No issues with it

If you’re looking for a solid mid-tier 90° offset Picatinny mount and don’t want to overspend, this LONSEL mount offers very good value. It hits most of the functional requirements—offset design, decent materials, clean look. I’m giving it 4 stars because while it does what it says, it doesn’t quite hit the premium “nothing else to improve” mark. Would I recommend it? Yes — especially for the budget-conscious builder who wants to add a side-mounted accessory and doesn’t need the most high-end brand. Just be sure to check fit/clearance for your specific rail and accessories, and take the time to align and torque it properly.

Good product at a good price. Never had any issues with these, they are as good as any name brand ones but are cheaper. Always packed good and easy to use.Will buy again and again.

Used these on my rock island arms vr80, great value and flawless fit for my build. Looks clean and installed fast. Very sturdy and versatile!

The finish is black matte anodizing, its commercial spec Type 2 anodizing and not mil-spec Type 3 hard coat anodizing. It also is not flat black matte like the pictures, it is black matte but its semi-glossy black matte. So if you were keeping with flat black matte mil-spec Type 3 hard coat anodizing this is not going to be that. Dimension-ally in terms of the 90 degree picatinny rail portion it meets mil-spec. But the clamp part, the 'V' valleys that grip the rail, although it does tighten down and stay put its very slightly out of mil-spec on angle and it looks like they used the weaver standard on this part. Its not a big deal but keep an eye on it when tightening to make sure your pic rail edges seats in the valleys before you tighten completely. Personally, I've decided to not use them long term. The only reason I got them was I needed something quick for short term use to set up a few IR lasers on a couple of rifles and zero them to evaluate while waiting for my mil-spec 90 degrees to arrive for the permanent install. Materiel and workmanship is good quality. I'm rating it 4 stars though for inconsistent dimension standards used - 90 degree pic section is mil-spec dimensions but clamp portion seems to be weaver standard and not mil-spec.

Good build quality, easy to install 👍

exactly what it looks like. Solid device made of steel. Fits a Picatinny rail very easy with no shaking. Holds a flashlight, and the rail holds the device solidly as well. Many aftermarket pic rail adapters or devices are too big or too small or otherwise out of spec. Both the rail grabber the right angled rail are in spec, and sturdy.

The mount is definitely low profile and to have it at a 90° where you can mount a light to that if you don't have picatinny or m lock on the side of your handguard is definitely a blessing, but the hardware is cheap and the piece that you loosen so that it can expand over top of your existing picatinny rail does not sit back flush with the rail and the mount after you tighten down the screws. The screws themselves don't stay tight. I bought loctite and I'm just hoping that I didn't strip the heads of these cheap screws too much to get it on my wife's tool the way that it's supposed to be on there. The mount and the route themselves are solid but definitely cheap hardware. They should include better screws and possibly a small tube of loctite
