AR removal and use the spring from the black one to spring double the other, that's what I'd do.

If it's an old Nite Finder, the AR is held together with a simple pressure fitting. If it's a new one, you'll have to boil it apart, or cut and weld it back together. Look for mod hints on YouTube.

(Edit:) If you have access to a wood chisel, you can just rock it back and forth over the posts that hold the AR in place. The knock out method, as Agent Zero noted, is difficult.
