Looking for some advice on a custom build. Rifle will be chambered in 300 WM and equipped with a Silencerco Omega suppressor. the only down sides of the suppressor are the added length to the rifle, and the rifle being muzzle heavy. On a rifle with a 24” steel barrel, when carrying with a sling, the rifle wants to flip over backwards, muzzle down. To solve this, I’m considering either a 24” carbon fiber barrel, or a fluted, Sendero profile barrel at 22” in length. Also considering going with an adjustable comb stock (Manners PRS2 or similar) to add a little weight to the buttstock end of the rifle, to provide better balance. Looking to maintain 0.5 MOA or better and greater than 3000 FPS with a 180 grain bullet. Which barrel option would be better, and why?
