I had the BOSS system on one rifle, and I will never own another rifle with the BOSS. It took as many shots to dial in the BOSS , as it normally takes me to develop a load, and in the end, it was no more accurate than my other rifles. It also had a habit of working loose, resulting in the groups opening up, and the point of impact wandering slightly. It was extremely loud to the shooter. I fired one round in an open field without hearing protection, and then I sold the gun. Lastly, the BOSS equipped rifles have shorter barrels to compensate for the length of the BOSS, so they produce less velocity than the same rifle without the BOSS.
