Best Scope Cameras for Recording Through a Rifle Optic

Buy the ScopeMate S28 Gen2 4K when your scope's ocular measures 51.6 mm or less. It records 4K at 60 fps, double the Triggercam 2.1's 4K frame rate, 1080p120 and 720p240 cover slow-motion review, and ScopeMate rates the replaceable 18650 for up to 13 hours, enough for a full range day. The cost is 280 g hanging off the eyepiece, and the standard S28 has no touchscreen.

The Triggercam 2.1 ($620) is the pick when you want capture on dedicated hardware controls. Its Quick Record sequence runs through the Power and Record buttons, it records 4K30, 1080p120, and 720p240, and it takes U3 cards up to 128 GB. Triggercam states 32 to 48 mm compatibility with 40 to 47 mm sleeves supplied, requires 37 mm of follower depth, and excludes Swarovski Zi scopes outright, so a scope that matches on diameter can still fail the fit check. The trade-offs are a 2.5-hour recording rating against ScopeMate's up-to-13-hour rating and a 453 g body, 173 g heavier than the S28 Gen2.

The ScopeMate S28-TSC Max (from $600) keeps the S28 recording menu, the up-to-13-hour replaceable battery, the IP64 rating, and the 280 g weight, then adds a touchscreen and a choice of Standard or FFDR (Full FOV Dual-axis Recording) configuration. Those are two separate configurations, not a mode you switch between, so pick the framing before ordering. Its stated ocular limit is 52 mm.

The ScopeMate S18 Gen3 ($350) is the lower-cost dedicated camera. It records 2.7K60 and 1080p at up to 120 fps, weighs 260 g, and runs the same replaceable 18650 rated for up to 13 hours. Resolution stops at 2.7K and its 36 to 48 mm eyepiece range is narrower than the S28 models. Its power-on recording option starts capture when the camera turns on, which removes one step before a string.

To record through a rifle optic, mount and zero the scope, match the camera or adapter to the measured eyepiece, center and focus the reticle in live view, confirm eye relief and clearance, and start recording before the first shot. The same seven steps apply to dedicated scope cameras and phone adapters.

1. 1. Choose the recording view. Use a dedicated eyepiece camera or a phone-to-scope adapter when the reticle and magnified sight picture must appear. Use a Picatinny or M-LOK camera only for a forward-facing point-of-view angle.
2. 2. Measure every mounting surface. Measure the ocular or eyepiece diameter and the straight clamp area. The Triggercam 2.1 also needs 37 mm of follower depth, and the G-Line adapter needs a cylindrical eyepiece with no buttons or bulges where it clamps. For rail cameras, confirm Picatinny or M-LOK and the camera's mounting interface.
3. 3. Mount, level, and zero the optic first. Finish the scope installation, leveling, torque, and zero before adding camera weight to the eyepiece.
4. 4. Set magnification and focus. Choose the magnification and target distance you will record at, center the camera on the reticle in live view, then focus the camera or phone on the scope image.
5. 5. Check eye relief and clearance. Dry-check the shooting position, eye relief, charging-handle clearance, cables, and controls before live fire. A phone mounted directly behind the eyepiece occupies the normal viewing position.
6. 6. Start capture before the shot. Start recording from the camera or phone controls before the firing string. The ScopeMate S18 Gen3 can begin recording at power-on, the Triggercam 2.1 uses its Quick Record sequence on the Power and Record buttons, and phone adapters record through the phone's own camera.
7. 7. Review and adjust. Record a short test clip and check reticle centering, focus, horizon, glare, and vibration before recording the full session.

The Side-Shot Phone Mount ($199.99) is the phone-to-scope adapter to buy when you want to keep looking through the scope while the phone records. It holds the phone beside the optic on a scope-tube clamp, leaves the eyepiece open, and includes a snap-on stabilizer bar. The kit ships with one clamp, chosen from 1 inch (25 mm), 30 mm, 34 mm, 35 mm, or 36 mm, so order the size that matches your tube.

The G-Line Sharp Sight Full Pack ($227.29) is the rigid behind-the-eyepiece phone scope mount. It ships with one eyepiece attachment, ordered in a 38 to 46 mm or 46 to 52 mm size, the universal plate takes a phone with or without its case, and the main structure is aluminum. It needs a cylindrical ocular: a button, bulge, or other interruption where the attachment sits prevents the clamp from seating, and the phone takes the position your eye would.

The Skopecam 3 Ranger Pack ($195) is the complete behind-scope kit: phone mount, stock extender, and a mount for a Picatinny rail on the scope, with three-axis adjustment and a tool-free quick release. It is built around a stated 25 to 30 mm scope diameter and phones with a corner-mounted camera or camera cluster, and it records through the phone's native camera app.

The Spectrum Optics Universal Phone Adapter ($25.99) is the budget digiscoping adapter. It clamps eyepieces from 1 to 2.1 inches in outer diameter, Spectrum lists rifle scopes among its compatible optics, and the body is aluminum with rubber-padded phone contacts. It is the lowest-cost scope camera adapter here, and Spectrum publishes no live-fire recoil rating for it.

A Picatinny or M-LOK camera mount records what the rifle points at, not what the scope sees. The camera looks through its own lens, so no reticle and no magnified sight picture appear. Use one for a forward point-of-view angle, and run it alongside an eyepiece camera when you want both views.

The RunCam Scope Cam 2 4K ($189.90) is the self-contained option, with an integral Picatinny mount. Four lenses set the framing: 40 mm and 35 mm for distant subjects, 25 mm for rifles and SMGs, and 3.6 mm for close range. It records 4K at 30 fps, 2.7K at 60 fps, and 1080p at up to 120 fps, and Flashback mode saves the 10 seconds before a button press and the 15 seconds after it. RunCam lists this scope cam in its airsoft category and publishes no recoil rating for powder firearms.

For an action camera you already own, the Samson Manufacturing M-LOK Direct GoPro Mount Kit ($52.25) is the rigid choice: a 6061-T6 aluminum base and mount that attach directly to a standard M-LOK handguard on the centerline and accept a GoPro in its factory housing. The Left Side Armory M-LOK Action Camera Mount ($14.99) is the lightweight alternative, a 24 g Nylon 12 mount with M-LOK hardware and a camera thumbscrew included, for GoPro, Insta360, and other two-prong action cameras. Both need standard M-LOK slots, and a camera without the matching interface needs an adapter.

Mount, level, torque, and zero the riflescope before a camera goes on it. A scope camera records whatever the optic shows, so a canted reticle or a loose ring ends up in every clip, and the dedicated cameras in this guide add 260 to 453 g at the eyepiece.

The optic mounting basics guide covers eye relief, leveling, and ring torque. Choose rings by tube diameter with the best scope rings guide; that tube measurement is also how the Side-Shot clamp is ordered. On an AR-15 running an LPVO, the best LPVO scope mounts guide covers cantilever mount height and tube fit, and the Skopecam 3 Ranger Pack's scope-rail mount needs a Picatinny rail on the scope itself.

Zero last, then leave the scope alone. The optic zeroing guide walks the process, and the optic zeroing simulator lets you rehearse the adjustments before range time. Once the zero holds, fit the camera, align it in live view, and recheck eye relief with the camera in place.
