BOSS® and BOSS® - CR

BOSS® and BOSS® - CR

The BOSS-CR accessory offers all the accuracy advantages of the original BOSS device without the muzzle brake feature. By simply replacing the original BOSS forward weight and recoil reduction components with the one-piece, no-hole BOSS-CR accessory, only the reduced recoil of the original BOSS is sacrificed. The BOSS-CR accessory is designed to fit only BAR Mark II and A-Bolt centerfire rifles previously factory-fitted with the BOSS.

A key component of the BOSS is a muzzle brake, which reduces recoil by over 30%. Like all muzzle brakes, substantially increased noise occurs. Always wear hearing protection.

Browning's Ballistic Optimizing Shooting System (BOSS) is a patented breakthrough in rifle accuracy. When any rifle is fired, the barrel goes through a series of vibrations as the bullet leaves the muzzle. The variations of these vibrations greatly affect the accuracy of the rifle. Controlling these vibrations will greatly control the accuracy of the rifle. Browning's BOSS allows you to control the vibrations of your barrel so you can shoot groups you didn't think possible.

How does the BOSS work?

The BOSS simply tunes the vibrations of your barrel. This allows the bullet to leave the barrel the split second it is stationary. Your BOSS manual has a list of settings for each caliber and bullet weight. Adjusting your BOSS to these "Sweet Spot" settings allows you to find the instant your barrel is stationary. The result is accuracy never achieved before by an out-of-the-box rifle.

The BOSS has been available on many Browning rifles over the years but is usually found on only select models, sometimes not seen on the Browning Website. (By agreement with Browning,  the Browning BOSS was also historically found on some Winchester rifles as well.)

This type of accuracy has only been available for benchrest reloaders who spend hours developing loads that leave the barrel between vibrations, or custom gun makers who develop barrels for specific loads. But the BOSS gives you much more than just accuracy. Depending on the caliber, the Browning BOSS system can reduce recoil by a third. This is something you will really feel. Less recoil means quicker follow-up shots and more comfort in the field and on the range.
