Called Remington this morning regarding my R51 that they have for repairs.
I was told that they are waiting on "updated" internal parts to be available so that they may "update" the gun before it is returned to me. Could be "several" more weeks.
My guess would be that they will be replacing the breech block and possibly the barrel, as well as the rear sight.
Makes me wonder if they have halted production on new guns until updated parts are available, and will production or repairs get the parts first.
Remington sure is getting a black eye over this gun.
For what its worth, I bought a Springfield XDs 9mm just 2 days after I bought the R51. Until I sent the R51 in for repairs, I shot both guns side by side, same ammo, and same number of rounds. The XDs has since doubled the round count and there have been NO problems.
