Inteliscope was a phone-to-firearm-rail adapter paired with an iPhone app—not a conventional optical riflescope. The adapter held an Apple phone or iPod on a Picatinny or Weaver rail, while the app displayed a camera view with a digital reticle and other advertised tools. Its documented phone compatibility is historical; available sources do not establish support for current iPhones or iOS versions.

What Inteliscope was

The Inteliscope Tactical Rifle Adapter attached a compatible Apple phone or iPod to a Picatinny (Mil-STD-1913) or Weaver rail. The phone’s camera captured the view, and the app placed a reticle and other information on the screen. It was therefore a mount-and-app system, not a phone transformed into a conventional optical riflescope.

The original product description advertised portrait or landscape positioning, adjustable placement, quick-release mounting, reinforced polymer construction and the ability to view around obstacles. Those are manufacturer-promoted characteristics, not independent findings about durability or performance. [Engadget’s 2013 launch coverage]

What the app advertised

The version 2.3 entry in a third-party app catalog listed an “Intuitive Heads up Display,” 5× digital zoom, selectable reticles, ballistic drop compensation, video recording and playback, compass and GPS positioning, local prevailing-wind information, a shot timer, flashlight and strobe. A 2013 release notice also described a sight-in method that shifted the background video while keeping the reticle centered. These are historical feature descriptions, not independent validation of precision, ballistic correctness or reliability. [AppAdvice’s Inteliscope listing] [The Tactical Wire’s 2013 release notice]

Which phones and app versions are documented?

The third-party catalog’s version 2.3 entry names iPhone 4/4S, iPhone 5/5s, iPhone 6/6+ and iPod Touch. This is historical compatibility information from that listing; it does not establish that Inteliscope works with newer iPhones, modern iOS releases or an app currently available through Apple’s App Store. [AppAdvice’s Inteliscope listing]

Later reporting and a retailer listing describe an Inteliscope Pro intended for a wider range of smartphones. That does not guarantee that a particular current phone fits, that its app can be installed, or that the product is in stock. Confirm the exact phone dimensions, operating-system and app support, mount interface, included parts, seller and availability before relying on any listing.

What one review observed about the mount

In a 2014 review, Paul Helinski of GunsAmerica Digest described the phone holder as a screw-adjustable squeezing mechanism with rubber feet, rather than a clip. He reported that the phone could move unless the holder was tightened firmly, and that he needed time to understand the app’s sight-in control. Those observations apply to the reviewed product and experience; they do not establish how every unit or the later Pro version performs. [GunsAmerica Digest’s 2014 review]

Price and availability: historical figures, not a current quote

Historical launch figures differ: Engadget’s reproduction of a May 2013 announcement gave a $69.99 pre-order price, while The Tactical Wire’s 2013 release notice described the adapter at $99. Neither amount is a current price. A Sentry retailer page indexed within the last several months listed Inteliscope Pro at €180 including VAT, with shipping extra; that listing does not confirm current stock, official authorization or phone fit.

What the available evidence does not establish

  • There is no independent performance data here establishing accuracy, ballistic correctness, durability across phone models or suitability as a substitute for a conventional optic.
  • No current app-store availability or compatibility with modern iPhones and iOS versions is established.
  • A retailer listing does not by itself establish present inventory, official authorization or compatibility with a named phone.
  • No general legal conclusion is supported. Rules depend on location and circumstances; check current official guidance for your jurisdiction before use.

A 2013 Austrian review relayed a ministry view concerning that country’s law and a specific product-and-light configuration. It is dated and jurisdiction-specific, so it cannot establish legality elsewhere or current rules. [GunsAmerica Digest’s 2014 review]
