Need to upgrade from current scope on my 25 Bullpup. Have Hawke 4x16x44 sf 30mm compact. Not very clear & not enough eye relief. Need to be able to see pellet hole @ 50 yards. Considering Aztect Emerald 3x18x50 and Sightron STac 4x20x50. Side focus a must. Dont want minimum power above 4x or max more than 20x. Second focal plane is fine with some type of graduated reticle Thanks guys
