Much of the time spent at the range can often be waiting on a weapon to cool. With semi-auto triggers able to take weapons to near cyclic speeds or bolt-action barrels needing to keep cool to protect the barrel, heat is a major problem on weapons. Its why we have handguards.

Prior to the last few years, trying to get a weapon to cool was often just letting mother nature work. While various enterprising individuals rigged up pressure-hose systems, that same entrepreneurial thought has been slowly turning into marketable products like BarrelCool, and the Caldwell AccuMax, both of which have their weaknesses.

Seeing the opportunity and a better solution is the  Chamber Chiller. Announced originally in 2015, the product has been working its way through prototyping stage and is now into beta testing, where one can actually purchase one of the products including the latest iteration, the Beta 60. As the name implies, the Beta 60 is a beta unit using a 60mm brushless fan. Power comes from four AA batteries.

With a 10.4 mm nozzle, the Beta-60 is ideal for “battle rifle” calibers and up including, but not limited to:

.22-250 Rem, .243 Win, .260 Rem, .270 Win, .280 Rem, .30 Rem AR, .300 RUM, .300 Win Mag, .30-06 Spg, .308 Win, .338 Lupua, 6mm BR, 6mm CM, 6mm Dasher, 6mm XC, 6×47 Lapua, 6.5×47 Lapua, 6.5×55 Swede, 6.5-284 Norma, 6.5 Creedmoor, 6.5 SLR, 6.5 SAUM, 7mm Rem SAUM, 7mm WSM (+More!)

For those of us shooting AR-15s and intermediate calibers, the Omega-50 is the best bet with its 8.0mm nozzle.

.22 Nosler, .220 Swift, .22-250 Rem, .223 Rem, .243 Win, .260 Rem, .270 Win, .280 Rem, .284 Win, .30-06 Spg, .308 Win, 5.45×39, 6mm BR, 6mm CM, 6mm Dasher, 6mm PPC, 6.5 Creedmoor, 6.5-284, 6.5 Grendel, 6.5 SLR, 6.5×47 Lapua, 6.8 RSPC, 6×47 Swiss, 6×47 Lapua, 7.62×39, 7mm-08 Rem (+More!)
