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.
