First, my wife's Patriot Bantam came with what I'm assuming are Weaver 20 MOA mounts, not a rail, plus a really inexpensive scope. At the range we couldn't get the scope to zero at any distance. We had the elevation maxed out and were hitting about 2 feet under the 100 meter target. I just attempted to boresight the new scope (a Vortex Viper 6-20x50). Even with the elevation bottomed out I still can't get the cross hairs low enough to come close to the target. Is there a picatinney rail that fits a short action Patriot? I would prefer a 0 MOA rail, but would take a 20 MOA if that's all that's available. Thanks for any suggestions.
