Im looking at acheiving an 15mm or 0.591" rise to bring my 3x magnifier and red dot inline** A: It raises roughly 2cm above the top picattiny rail, meaning anything you attach will have its base/bottom starting at 2cm above the weapons rail. I've done a video showing this. It's in one of my other answers to this question so help yourself visually. 😸 Tabi **Q: How much taller will scope become?** A: Hope these shots help. They were taken 30mins ago and are very clear friend. (Any wobble you see is due to my moggy playing with the shoulders trap, lol. She approves all my videos/pictures/activities 😸) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Value for money *by D***. on 4 December 2020* Very good, well made great finish ### ⭐⭐⭐⭐⭐ Affordable Picatinny Rail Raiser *by J***S on 6 October 2019* Is as described. Nothing of note to say, which is what you want for such a simple product. ### ⭐⭐⭐⭐ Good risers that do the job, but... *by M***R on 17 July 2020* I bought two of these risers to attach a Burris LaserScope to the Picatinny rail on a Tikka Tx3 Tac A1. They arrived a day early and on opening the package I was pleased with how solid and well made they appeared. I fitted them to the rails but I just could not get them to line up with any accuracy. Eventually I found that the flat lug which forms the securing screw, had been fitted just slightly proud meaning the bearing surface would not sit flat. I had to carefully file it down with needle files which unfortunately took off the nice finishing. It now fits and secures the scope very firmly to the rail. Overall I still feel happy with the risers, as they do the job and were good value. It was a shame that one finishing touch let it down. --- ## 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.jp/products/73555913-85mm-riser-mount-extension-picatinny-rail-scope-mount-base-adapter](https://www.desertcart.jp/products/73555913-85mm-riser-mount-extension-picatinny-rail-scope-mount-base-adapter) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-04-28*
