It is well-established that mid-barrel tuners can work on rimfire rifles, and we also know that certain types of materials (such as rubber, cork, and Delrin) can have beneficial damping effects on both rimfire and centerfire barrels. Given these facts, we were quite interested in the new Flexi-Weight System introduced by AirForce Airguns at the 2010 SHOT Show.

The Flexi-Weight system consists of a cluster of 3 to 6 metal weights, held in place by a rubber O-ring. Multiple Flexi-Weight clusters can be installed on a single gun and the fore-to-aft position is easily adjusted. The shooter can simply slide a Flexi-Weight cluster back and forth along the barrel until he finds the optimal position.

We have no idea whether Flexi-Weights can improve accuracy on a centerfire rifle, but it’s worth a try. Flexi-weights are affordable ($29.95 for a set of five, 48 gram weights) and you can slip them on your barrel without cutting threads or making any other permanent modifications. The weights are designed to fit a 1.25″ diameter tube. For more info, visit Airforceairguns.com or call (877) 247-4867. Airforce Airguns is a U.S. company based in Fort Worth, Texas.
