Cool your barrel with ease.

A chamber flag with an integrated fan to cool your barrel. Cuts cooling time in half compared to regular convection, and the Caution Yellow paintjob complies with approved chamber flag color standards.

Keep your barrel cool, and your shots on target. Great for cold bore mapping, competition shooting, or any day at the range.


The ultimate barrel cooling solution.

Bring your rifle down to ambient temperature in 5 minutes flat.
Barrelcool works great, but when you need that extra boost, get yourself a BarrelBlizzard. Snap it onto your scope, and let the 2 fully 360° swivel fans cool your action, your barrel, or even yourself. It'll bring your gear down to ambient in 5 minutes, perfect for varmint hunting, load development, or just getting more time on the range.

Free shipping for BarrelBlizzard! Battery included.

BarrelCool RestEyelign


Makes front rest setup and alignment a breeze.

The easiest and fastest tool to get your front rest aligned dead on target, the very first time. Drop it into your rest, then use the holographic sight to align the rest to your target. When you place your rifle down, it'll be lined up with your target, no more setting and re-setting the rest.

Fits any 3 inch OR 4 inch front rest! Comes with OR without the holographic sight. Get to shooting quicker and use RestEYElign for your front rest.

Barrelcool Dri-gun


The 2 oz solution to shooting in the rain. Keep your action and chamber dry.

It starts raining at the range, so what do you do? Umbrellas are against competition rules, tarps get in the way of your scope adjustments, and letting your chamber get wet is NOT an option...

Use Dri-Gun! Just snap it on and you've got a scope-mounted rain canopy. Durable, lightweight, and stays out of the way. Forget about the rain and focus on your target.
