I have been thru this crap with Remington and will never buy another one of their rifles without a custom barrel.
Mine needed the following
New trigger
new crown on the barrel
recoil lug was not centered
firing pin had slow fire a couple times in each 25 rounds fired, replaced.
Cases came out of the chamber like bananas.
New barrel, shoots consistently under 1/2"
Factory gun a tragic mistake by Remington as it was garbage.
