Aimpoint 9000L: Available with 2 MOA or 4 MOA dot sizes, this long version is perfectly suited for large caliber hunters looking for a red dot sight with a more traditional look. The 9000L is fully waterproof, has the same battery life as other Aimpoint red dot sights, and fits on any rifle with a 30mm mounting configuration. Aimpoint 9000SC: This red dot sight is nearly identical to the Aimpoint 9000L, but specifically tailored for shorter action hunting rifles with 30mm rings.
