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.
Thanks for the tip Red Lion, I just ordered the Ventliners for $3/each from them, got 4 of them, that should last about a year I think. Guess I should have gotta Breach plug also just to have an extra handy, will do that next time.
