I owned a boss equippedBAR in 7mmremmag for a short time.Accuracy was very good with very mild recoil due to the heavy weight and the muzzle brake.My rifle was very well maintained and properly lubricated,but it did jam onceon me in very cold wet weather.It also jammed once under similar conditionsforthe friend that I sold it to.The jamming incident was a little upsetting but not nearly as much as the BOSS.It often came loose which caused the point of impact to change.Also you must never fire a boss equipped rifle even a single time without hearing protection.The muzzle brake increases the noise to such a level that a single shot caused my ears to ring for over an hour.Yet another disadvantage of the BOSS equipped rifles is that they come with shorter barrels to compensate for the length of the BOSS.Cartridges such as the 7mmremmag and 300win mag really aren't a great advantage with the short barrels.In fact a 280rem bolt rifle basically duplicated the velocities that my boss equipped 7mmremmag produced.I might possiblyconsider another BAR rifle if my hunting conditions were less severe,but I will never own another boss equipped rifle.
