Currently have a 22" barrel 6.5 suppressed with a rex mg7k. You get used to it way faster than you think. The only times I've noticed it is when I accidentally touched stuff near the ground with the muzzle. If you just carry it muzzle up you'll never notice. All that being said, my future rifles will have a much shorter barrel. I base the length upon the caliber but I'll float between 16-18 on most guns and maybe the occasional 20". It's not worth changing a good shooting rifle/barrel over but it is something I'll plan for in the future. I also would never shoot over 500 and try to keep it under 2-300.
