Review: Picatinny mount and don’t want to overspend - 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. ## Features - 90 Degree Offset Picatinny Rail Mounts: 90° Offset Side Rails Mounts allows the attachment of flashlights, lasers, red dot sights, optics or other. - Fits 21 mm Picatinny System: LONSEL Offset Rail base mounted on standard 21 mm picatinny rail platform, ensure mounting hunting accessory seamlessly. - 4 Slots Offset Picatinny Rail: 90° Offset Rail Mount with low profile & lightweight & hollow-out design to reduce weight. 2 Pack 4-slots 90 degree rails, with matched screws and 2 pcs allen wrench. 4 Slots weight: 1.04 Oz. - Stable Mount, Solid & Durable: Precision machining of high grade 6061 aluminum alloy in black matte anodizing finish, and high tensile steel screws, durable & lightweight, don't worry wobble or shake. - Side Clamp Block Design & Easy To Install: One side clamp block design with 2 built-in clamp fixing screws, easy and quick to remove or mount via allen wrench tool, It can be installed left or right, won't damage your rail. ## Technical Specifications | Specification | Value | |---------------|-------| | Item Package Dimensions L x W x H | 4.88 x 3.03 x 0.91 inches | | Package Weight | 0.07 Kilograms | | Item Dimensions LxWxH | 1.77 x 1.61 x 0.83 inches | | Item Weight | 0.06 Kilograms | | Brand Name | LONSEL | | Warranty Description | 6-Month Warranty | | Model Name | LS90DOPR | | Color | Black | | Material | Aluminum Alloy + Steel | | Suggested Users | unisex-adult | | Manufacturer | LONSEL | | Style | 4 Slot - 2 Pack | | Included Components | Allen Wrench & Screw | ## Images ![90° Picatinny Offset Rail Mount, 3 4 5 Slots 90 Degree Offset Picatinny Rail Mounts Aluminum Low Profile Adapter for Flashlight Laser Sight Optics - Image 1](https://m.media-amazon.com/images/I/618Kbtv6afL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good rails *by K***S on July 14, 2026* Good product at a good price.
