Most Helpful Positive Review Battery cap
This cap fit perfectly on my aimpoint ACO and also my PRO. I used it to put the rubber strap connecting the adjustment caps and battery cap. Perfect fit. I also purchased new adjustment knob caps as well from here and all worded well.

Saved my optic

by kam, Verified Owner from SC, United States Written on January 21, 2025
Had a Comp M4 that was given to me but cap was stuck on from previous using owner using alkaline batteries. Cut the old one off with a dremel and put this one on. Works like a charm.

Aimpoint CompM4S

by Mr. Bear, from CA, United States Written on October 28, 2019
If you've ever had a catastrophic battery failure in a CompM4, this is the replacement for you. I had a AA battery commit ritual suicide, which apparently borked the *two* springs inside of the cap. I managed to pop the spiral spring up, but the flat-spring in the top of the cap was not so fortunate. Just replace the cap and you'll be fine.

Got here fast, came out of the plastic bag fast, installed fast. Don't know what else to say.

M2 battery cover / battery cap

by Legacy Reviewer, Verified Owner from MN, United States Written on January 25, 2011
Overall a nice little item, Aimpoint does not sell spare parts direct, they refer you elsewhere for parts, so I was glad opticsplanet had this piece, as it is actually a fairly difficult to find item. The piece fits easily and is typical Aimpoint - well made & reliable.
Pros: Great replacement
Would recommend: Yes
