Review: Perfect for my setup! - Very well made and versatile mount. I have an unusual rear sight setup and this is what I’ve been looking for. I have my magpul BUIS mounted backward as far forward on the receiver pic rail as possible, then I have this mount with a Holosun 507c offset directly behind that and it’s perfect. My cheek weld and head position is the same for the iron sights or the red dot, I just slightly rotate the rifle for whichever I want to use. I could see an issue if I wanted to add a 3x prism scope (or any scope) with how tight to the rail the mount is, but for me it couldn't be better. Comes with pins and screws for all kinds of red dots. Would buy again 👍 ## Features - VERSATILE MOUNTING OPTIONS - The ADE HM8 optic mount allows the user to mount a varieties of Red Dots at a 45 degree angle alongside your primary magnified optic for optimal aiming versatility when the situation gets up close and personal. - RIGHT OR LEFT HANDED FUNCTIONALITY - The ADE HM8 optic mount attaches to either side of a Picatinny rail to accommodate left or right handed shooters. - FITMENT - Compatible with Any red dot with footprint of with Doctor footprint, such as Vortex Venom/Viper, Burris Fastfire, ADE RD3-006, RD3-009, RD3-012, RD3-013, RD3-015 red dots - RED DOT COMPATIBILITY - Compatible with Any red dot with footprint of Triijicon rmr footprint, such as holosun 407c/507c, ADE RD3-020, RD3-023. - COMPATIBLE MODELS - Compatible with Any red dot with footprint of Shield RMS/RMSc footprint, such as Leopold Deltapoint Pro, Sig Romeo Zero, Hex Wasp, Swampfox Sentinel, Burris Fastfire C, Holosun 407K/507K/ESP Carry. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B3Q6HQC7 | | Best Sellers Rank | #137,725 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #379 in Sporting Optics Mounts | | Brand | Ade Advanced Optics | | Brand Name | Ade Advanced Optics | | Color | Black | | Compatible Devices | Vortex Venom/Viper, Burris Fastfire, ADE RD3-006, RD3-009, RD3-012, RD3-013, RD3-015, Holosun 407c/507c, ADE RD3-020, RD3-023, Leupold Deltapoint Pro, Sig Romeo Zero, Hex Wasp, Swampfox Sentinel, Trijicon RMR, Shield RMS/RMSc | | Customer Reviews | 4.0 out of 5 stars 119 Reviews | | Field Of View | 45 Degrees | | Global Trade Identification Number | 00640978407731 | | Item Weight | 0.06 Kilograms | | Manufacturer | Ade Advanced Optics | | Manufacturer Part Number | HM8 | | Material | Aluminum | | Material Type | Aluminum | | Model Number | HM8 | | Mounting Type | Picatinny Mount | | Night vision | No | | Product Style | Tactical | | Reticle Type | Red Dot | | Sport | Hunting | | Sport Type | Hunting | | Style | Tactical | | UPC | 640978407731 | ## Product Details - **Brand:** Ade Advanced Optics - **Color:** Black - **Style:** Tactical - **Sport:** Hunting - **Item Weight:** 0.06 Kilograms - **Material:** Aluminum - **Compatible Devices:** Vortex Venom/Viper, Burris Fastfire, ADE RD3-006, RD3-009, RD3-012, RD3-013, RD3-015, Holosun 407c/507c, ADE RD3-020, RD3-023, Leupold Deltapoint Pro, Sig Romeo Zero, Hex Wasp, Swampfox Sentinel, Trijicon RMR, Shield RMS/RMSc - **Mounting Type:** Picatinny Mount - **Night vision:** No - **Field Of View:** 45 Degrees ## Images ![Red Dot Sight 45 Degree Offset Mount Compatible with Shield RMS/RMSc/SMS/SMSc, ADE RD3-018 Spike, RD3-021 NUWA, Holosun 407K/507K,Vortex Venom/Viper Red Dot - Image 1](https://m.media-amazon.com/images/I/71EwYsg0oeL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid build *by W***. on November 6, 2025* Solid mount, but would not fit with Sig MSR LVPO, on top rail of AR. ### ⭐⭐⭐⭐⭐ Perfect for my setup! *by E***H on December 8, 2023* Very well made and versatile mount.
