New Product: Chamber-Flag Fan Device Cools Down Hot Barrels

BarrelCool fan battery cooling safety chamber indicator flag heat pump

The BarrelCool is an innovative, compact barrel-cooling device that also serves as an empty-chamber safety flag. A small, battery-powered fan drives cooling air through the barrel’s bore. Yes it really works — manufacturer-provided data shows that BarrelCool significantly reduces the time it takes to cool down a hot barrel. Look at the chart above to see what to expect.

In the past, folks have tried various methods to cool barrels: water flushed through the bore, CO2 tanks, even battery-operated fish pumps. BarrelCool is a simpler, less costly, and much handier solution. Priced at $34.99, this small device can definitely save you time at the range. Potentially it can save you money by extending barrel life. To see how Barrelcool works, visit BarrelCool.com. There you’ll find video demos of BarrelCool units in both bolt-action and AR-type rifles.

BarrelCool Range Reports from Forum Members
“Early adopters” of BarrelCool have been impressed so far. Forum member Comrade Terry said: “At the range, I spend a good bit of time waiting for the barrel to cool between shot strings. I fired my usual 50 rounds today, and (though it was 85° today) I was able to leave the range 30-40 minutes earlier than usual thanks to the BarrelCool. I like it!” Another Forum member, J-Rod, reports “Did some load development on my new rifle Friday. This used to take forever due to the barrel heating up outside in full sun (90° ambient). I’d say this little gem cut about two hours off my normal shooting time. I got home early and the wife was happy — what’s that worth?”

How and Why BarrelCool Was Invented
BarrelCool originated from the idea that cease-fire periods would be a great time to cool a barrel. During cease-fires, most ranges and matches require empty chamber flags in the gun so that the range officer and everyone on the firing line can see visually that the gun is in a safe condition.

BarrelCool inventor Bryan Sumoba explains the advantage of Barrelcool: “The challenge with the previous barrel-cooling methods is one would have to be present to run the device, it required additional steps such as running patches down the bore, or it gets in the way of a required empty-chamber flag. BarrelCool now allows the shooter to cool the barrel down simply and easily while having the empty-chamber flag in the firearm.”

Sumoba says BarrelCool significantly shortens the time needed to cool down a hot barrel: “In controlled testing, it took about half the time to cool the barrel from 140 degrees F to 100 degrees F (more in some cases depending on the barrel contour/length and ambient temperatures). Our customers also report significant reductions in the time it takes to cool down a hot barrel. At a recent 3×1000 F-Class match in Sacramento, one shooter fired 25 shots out of his 7mm RSAUM and got the barrel to the point where it was too hot to touch. In most cases, the barrel would still be very warm/hot by the time the next relay started. We placed BarrelCool in his firearm and within 30 minutes, the barrel was back to near-ambient temperature. Other observers mentioned that the air coming out of the muzzle with BarrelCool in the firearm felt like a mini blow dryer.”

Using three (3) CR123A batteries, a BarrelCool unit can operate for 7-10+ hours. BarrelCool fits both AR-style rifles as well as most bolt action rifles. The Hi-Viz yellow color stands out on the firing line and BarrelCool is small enough to fit in most range or gun bags. Manufactured in the USA, Barrelcool can benefit competition, precision, or recreational shooters who need to cool down their barrels more rapidly, while displaying “safe condition” on the firing line.

Sling Shooter vs. Mechanical Rest — Man vs. Machine

Man versus machine USAMU AR15 M16 High Power National Record

Can a human, with a sling, shoot as well as a mechanical rest? The answer is “yes” (at least once in a great while) IF that sling shooter can deliver a record-breaking performance. Here’s an interesting tale of man vs. machine from our archives…

The USAMU posed an interesting challenge — could one of their shooters match the performance of a mechanical rest? Who would win in this battle between man and machine? You might just be surprised. At 600 yards, with an AR-platform rifle, the results can be remarkably close, based on targets provided by the USAMU. When clamped in a test rig, a USAMU M16A2 produced a 200-18X group with handloads. The USAMU says this was “one of our better 20-shot groups at 600 yards, testing ammo from a machine rest”. Can a human do better?

Remarkably, a human soldier came very close to matching the group shot from the machine rest. The photo below shows a 20-shot group shot by a USAMU marksman with sling and iron sights, using USAMU-loaded ammunition. The score, 200-16X, was nearly the same. As you can see, the USAMU rifleman didn’t give up much to the machine rest, even at 600 yards!

In fairness, this was no ordinary human performance. The 200-16X score was a new National Record set in December, 1994. This was fired by PFC Coleman in an Interservice Match at Okeechobee, Florida. Brilliant Performance.
