Could use some help here.
16" mid length 5.56 sight in. I'm finally at the point where I think something is loose. Been trying to get a consistent string with various ammo. Here's what I get.. 3-1/2" groups with maybe 2-3 almost touching then one round fly's to left then group settles there for a string of maybe 2-3 then to the right same thing. Then one round fly's to top of target then another to bottom. I checked the sight and it is holding zero with different rifle. Get consistent strings with the other rifle and same ammo with lead-sled at same time so it's not a flinch. Looked at flash hider and no dings there. So I'm wondering if it's the barrel nut? Also using a lead-sled for all the sight in work, and like I said have used many different rounds with the same effect. Any ideas would be very appreciated. |

The bolt face is worn on one side only (compared to others and this was unusual) As well there is a worn away spot right in front of the Lug recess of the upper ( turned upside down it's on the right directly in front of the lug recess)
So does this possibly mean the barrel/upper/bolt&carrier are out of alignment? I know this would cause some problems. |
