I'm looking at getting a scope for a .22 I'll basically be using it for rats at night. So I'm looking for a scope that can focus at short range. I found two scopes that may suit my needs. They are very similar.
UTG 3-9X32 Compact CQB Bug Buster AO RGB Scope
UTG 30mm SWAT 3-12X44 Compact IE Scope
Now the Bug Buster shows that it has an Adjustable Objective and the SWAT has a Parallax Adjuster. Are these two features basically the same or do they perform different functions? I've did some research on the web but I get conflicting information. If they are different, then which of the two would be best for close range targets.
