The Area419 High Profile Red-Dot Adapter Plate for Delta Point Pro is a precision-engineered mounting solution designed to put a red-dot sight or other tactical accessory directly into your sight picture on a rifle scope mount. If you're running a Tactical One-Piece Scope Mount and want to add a secondary optic—whether a red dot, laser rangefinder, or dope card holder—this adapter brings serious rigidity and repeatability to the job. Built to Area419's exacting standards, it's the kind of piece that justifies itself the first time you need to trust your zero under pressure.
Area419 machines this plate from American 7075 aluminum and applies Type III hardcoat black anodizing for durability that holds up to field use. The mounting system uses a patent-pending dual taper design that mates to the top of the Tactical One-Piece scope cap (or 35/45-degree offset mounts), locking everything down with zero wiggle. Captive hardware keeps fasteners secure and eliminates the nightmare of losing a screw in the dirt. At just 1.5 ounces, it won't burden your build, and the CNC precision means your return to zero stays true shot after shot.
The DPP plate footprint gives you flexibility: it's compatible with a range of modern enclosed-emitter optics, including the Holosun SCS 320, Leupold Delta Point Pro, Sig Sauer Romeo X Pro, Vortex Defender ST and XL, C&H Precision DMO, and others that use the Delta Point Pro mounting pattern. Whether you're setting up a DMR, a precision rifle with a backup dot, or a hunting rig where a rangefinder makes sense, this is a legitimate option for shooters who demand strength and accuracy from their gear.

The plate accepts any optic using the Delta Point Pro footprint. That includes the Holosun SCS 320, Leupold Delta Point Pro, Sig Sauer Romeo X Pro, Vortex Defender ST and Defender XL, and C&H Precision DMO. If your red dot or accessory uses that mounting pattern, it will work.

The plate weighs just 1.5 ounces including all fasteners, so it's a minimal addition to your rifle's total package and won't meaningfully affect handling or balance.
Yes. It's CNC milled from American 7075 aluminum and hardcoat anodized to military specifications. The dual taper mounting system and captive hardware are designed to maintain zero through hard use, and the engineering is built for repeatability shot after shot.
