Too bad the tiny Phillips screw are soft metal and strip out easily which made one side non-functional for me after needing to reposition them. See pics. Need to look for a more durable option. ## Frequently Bought Together - WestHunter Dovetail to Picatinny Rail Adjustable Adapter, 11mm to 20mm Rail, 2Pcs - LONSEL Dovetail to Picatinny Rail Adapter 11mm Dovetail to 21mm Picatinny/Weaver Rail Convert Mount - Low Profile Scope Riser Rail Adaptor - Base Mount 3/8" to 7/8" Converter --- ## 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.co.za/products/227957066-westhunter-dovetail-to-picatinny-rail-adjustable-adapter-11mm-to-20mm](https://www.desertcart.co.za/products/227957066-westhunter-dovetail-to-picatinny-rail-adjustable-adapter-11mm-to-20mm) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-16*
