Just ordered a nova liberty pcp and looking for a budget scope. Looking to stay under $150 preferably $100. Looking at hawke and discovery and looking for suggestions on those or other budget scopes. Not sure what magnification to go with but thinking something like 3-9. Just using this gun as a plinker and to shoot birds. Also need to know what height rings I need to clear the magazine, smae mag as the gauntlet and maruader.
