For you 464 owners out there who wish to mount a scope on your rifle, per Mossberg customer service, the recommended base is the Weaver 403. That's the front base for Winchester '94 angle-eject rifles. You'll need two 403 bases for the 464. Do not get the rear angle-eject base, just two of the fronts and you're good to go. I've ordered mine from Midwayusa.com and will mount a BSA 2.5 X 20 long eye relief scope and let everyone know how it works out as soon as I can get to the range. This particular BSA is an inexpensive ($40-50) fixed power scope that I've had for years. It should be fine for most deer or wild hog hunting situations. It's only a hair over seven inches long and very light and shouldn't detract from the 464's superb "brush gun" characteristics.
