I used a Yankee Hill Machine Phantom Flash Suppressor for my 10in barrel, 5.56 pistol build. It has proven to exceed my expectations. On pitch black moonless nights I’ve gotten zero flash signature, even with rapid fire. Based on that a .308 YHM Phantom Flash Suppressor would be a no brainer. Except that 5.56 is not .308. So I thought I’d ask the experts, those of you that have or have used a 308 YHM Phantom Flash Suppressor what your thoughts are. Direct comparisons with others you have used would be helpful as well. Thank you for your assist gentleman.
