BarrelBiter – Clamp-On Shotgun Holder for Beavertail Boat Blinds

This version of the BarrelBiter is 3D printed in tough, flexible TPU and designed to clamp directly onto Beavertail boat blind rails, which are covered in canvas and closely match our clamp size. It also fits bare 3/4" EMT conduit, since it shares the same outer diameter.

⚠️ This item is made to order and may take 3–5 days to process before shipping.

The flexible TPU material provides a secure yet forgiving grip on your shotgun barrel. It stays flexible even in freezing temperatures as low as -30°F.

The barrel lock portion slides off the clamp base, allowing you to collapse your blind without the clamp or holder interfering with the canvas. This helps prevent bunching or tearing of the material when folding the blind down. The clamp can stay in place between hunts, helping preserve your setup without damaging your gear.

Upgrading from one of our original ABS versions? The new TPU BarrelBiter is fully compatible with the original clamp base from our first design, so there is no need to buy a full replacement. Just slide the updated holder onto your existing clamp and you are ready to go.

Barrel Fitment Disclaimer

The BarrelBiter is designed to grip most 12, 16, and 20 gauge shotgun barrels, but exact fit will vary depending on barrel diameter and mounting position. Some barrels may feel tighter or looser depending on taper or profile. Supported barrel diameters range from 0.650" to 0.827" (16.5 mm to 21.0 mm). If you are unsure about fitment, reach out before ordering, or give it a try and we can build a custom fit if needed.
