Want to try more from them ### ⭐⭐⭐⭐⭐ Custom gun build *by W***T on March 16, 2026* 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! ### ⭐⭐⭐⭐⭐ solid adapter that mounts properly and holds properly. *by M***H on October 14, 2025* 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. ## Frequently Bought Together - 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 - LONSEL 45° Picatinny Offset Rail Mount, 3 4 5 Slots 45 Degree Offset Picatinny Rail Mounts Aluminum Low Profile Adapter for Flashlight Laser Sight Optics - FENTUK Picatinny Offset Rail Mounts, 3 4 5 Slots 45 Degree Offset Angled Picatinny Weaver Rail Mount Aluminum Low Profile Adapter for Flashlight Laser Sight Optics --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/593933845-lonsel-90-picatinny-offset-rail-mount-3-4-5-slots](https://www.desertcart.com.pa/products/593933845-lonsel-90-picatinny-offset-rail-mount-3-4-5-slots) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-07-29*
