Gen 2 WMW Battery Cap for Aimpoint T2 and Acro P2

6/7/25 Update: We have finished another batch of these caps. I know we have a ton of customers that have been waiting for a while. Due to this we decided to put this batch on sale for y'all being so patient. This will also be the last batch of these for a little bit as now that this is finished we are working on transitioning our CNC lathe to the new shop, so we will not be able to produce more of these until it is up and going again.

This is a replacement battery cap designed for the Aimpoint T2 and Acro P2 Optics. The WMW cap will replace your OEM cap and allow for you to store a spare battery in the cap. It also does not require a special tool to remove it, thanks to the radius knob design. It is made from 7075 Aluminum and finished with hardcoat anodized black. This is the most functional spare battery style cap on the market. It not only allows the optic to function without the spare battery present but the delrin insert also provides isolation between the two batteries, so you do not need to worry about orienting the spare a certain way to not make contact with the in use battery.

The gen 2 cap has been redesigned to allow the use with both the T2 and Acro P2 optics. This is done by two different delrin inserts that are included with every cap. The thinner insert will be used when installing the cap on a Acro P2 and the thicker insert with the attached o-ring will be used when installing the cap on a T2 optic.

The cap assembly includes: the battery cap, T2 insert with o-ring, P2 insert and external sealing o-ring.

Due to the plastic divider design, this cap can be used with or without the spare battery in place. We also added a hole in the plastic divider so that you can see if there is a spare battery present when you remove your cap.

**Please know, that with all anodizing, there are variations and minor cosmetic imperfections in the finish; we picked out the majorly cosmetically flawed caps and they will be sold as blems.**

**While this cap can fit several other optics, it was designed to work specifically for the T2 and P2 optics.

**Battery, Optic and Mount are not included in Sale*
