My son has a Ruger 5.56 AR that says it has a 1/2x28 threaded barrel. My suppressor will not screw on his gun…about 1 revolution and it won’t go any further. His muzzle brake will screw on my guns but slightly loose. I measured his diameter and it’s about 5 thousandths bigger than my guns. Both have 14 threads on the half inch that is threaded. Anyone else experienced this?
Thanks
