You can also order the factory vent liners from Savage as well, with a phone call. It really depends on how much shooting that you plan to do....The RW vent liners perportedly last quite a bit longer, but again how much are you going to shoot? I have just stuck with the one hole factories, as I shoot maybe 50 rounds downrange all year.
I didn't see them on their Savage Store. Will give them a call. Thanks.
