Tuners work. So do muzzle brakes. But until recently, you had the choice of one or the other. Now with combo tuner/brakes you can tune the harmonics of your rifle barrel while enjoying significantly reduced recoil (and torque). This is a “Win-Win” for shooters of heavy-recoiling rifles.

Rifle accuracy and precision have come a long way in the past 15 years, particularly for long-range applications. The most recent tool to significantly improve precision is the barrel tuning system. The Rifle Accuracy System (RAS) developed by Precision Rifle Systems, incorporates a precision muzzle brake with the tuner. CLICK HERE for Product INFO.

This system potentially offers meaningful group size reduction through control of barrel harmonics. The RAS tuner/brake system was the subject of a June 2012 Precision Shooting (PS) magazine article, titled “Improved Rifle Accuracy” and was also featured in an article in the November 2012 issue of PS titled “Tuning with Confidence”.

Accuracy is the ability of a firearm to hit what it is aimed at within the limits of the precision of that firearm. Precision is the ability of a firearm to place successive shots in or near the first shot. A firearm that delivers one minute of angle (1 MOA) precision should, at 100 yards, place the bullet within roughly one inch of where it is aimed (actually 1.047″), or a sight adjustment should correct the problem. All the improvements in optics, manufacturing and components have allowed precision expectations to go from 1 MOA to 1/2 MOA or even sub-quarter-MOA.

What is the next frontier for the precision rifle? While all the other advancements were being made, advancements in the understanding and methods of managing the barrel vibrations were also being made. Once the rifle has been built and the loads developed, it is the management of the barrel vibrations that has the final influence on the bullet as it is leaving the barrel and the final influence on precision. The RAS has demonstrated with many different rifles and calibers that significant improvements can be made with a properly tuned barrel tuner system. What does this mean? Typically, there is a noteworthy improvement. In fact group size improvements between 30% and 60% have been observed with a properly-tuned barrel tuner system. This has been demonstrated on both custom rifles and loads and factory rifles.
