Just a quick update regarding the muzzle tuner.......After spending more time with this set up, I ended up adding more weight to this tuner. The aluminum was just too light and would not perform as consistently as the rifle did with the factory front sight installed. Looking to get the weight as close to the factory front sight as possible, I bored out the aluminum tuner and inserted a 22mm OD section of phosphor bronze, machined to fit the barrel. This got me very close to the weight of the factory sight. Still needing a bit of weight, I added a 6mm tuning spacer, machined the same as the muzzle tuner with a bronze core. This brought the total weight up to almost 10 grams heavier than the factory sight. Keep in mind that the factory front sight has more weight forward with the aperture on the very end. The tuner is now extended 6mm beyond the muzzle with 6mm spacer at the rear. A second row of M4 grub screws was also added to increase rigidity.
Much nicer set-up with consistent performance on target.
So, if anyone decides to install a muzzle piece on their scoped 300s, I would keep the mass weight at least as heavy as the factory sight, preferably a bit more. The 126g factory steel sight helps to tame the muzzle. Just sharing my experience.
