I purchased a B14R 22LR and it grouped like a shotgun at 100 yards and would not fire 3 out of 5 attempts, (I used only Match grade ammo) how could this rifle get out of the factory like that? they have a sub-MOA guarantee, the best I could get it to group is a little over 3 inches. I sent it back to Bergara to be checked, that was 6 weeks ago. I called Bergara support to get an update at 4 weeks and 6 weeks and got the same response (it has been assigned to a gunsmith and should go out next week)
But it did not!
