than start arguments. But I will mention this.The HK sniper rifle, the PSG1 uses polygonal rifling, as does the Larue Tactical Stealth sniper rifle, both considered a couple of the finest sniper rifles made, as do most HK handguns, as does the Glock 19 that our SEALS use. The polygonal rifling is known to be more accurate due to less friction and less deformation of the bullet, a better gas seal giving better velocities, longer barrel life due to less stress on the barrel and several other benefits. I own several Glocks and I plan on sticking with factory barrels. Why fix them if they aren't broken? Nuff said.
