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

Good works well on my ar. Want to try more from them

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!

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 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.

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 build quality, easy to install 👍

It works good. Likes: With a Leupold 3-9x 50 on medium height mounts, it can be installed/removed without removing the scope. Dislikes: The finish is poor. It’s not what I would consider a “gun grade” finish. If you don’t care about looks this is a good cheap solution. I’ve ordered a higher quality Picattiny offset adapter because I don’t like cheap looking parts on my rifle.

I use these to mount lights on the my PCCs, they work fine. They were cheap and they have held up so far.
