The Kastle Group BC-ACRO is a replacement battery cap built to fit the Aimpoint ACRO, and it is designed to take the place of the factory cap on the P-2 and C-2 optics. It adds a +1 extra battery storage compartment that holds an additional CR2032 backup battery, so a spare is ready on the optic if your primary battery dies or malfunctions. Plan on loading 2 batteries, because the cap will not function properly with only one installed.

The cap is machined from 7075-T651 aluminum and finished in black with Type III MIL SPEC hardcoat anodizing. An aggressive knurled edge gives you grip, so you can swap batteries without tools. Kastle machines it in its own facility and it is Made in the U.S.A.
