Description
The CVA AC1603 Breech Plug and Nipple Wrench is a solid steel service tool built by Connecticut Valley Arms for the complete takedown and reassembly of in-line muzzleloaders. Originally developed around the CVA Apollo line, this single-piece wrench is purpose-designed to fit CVA in-line rifle breech plugs and nipples, giving the engagement and leverage needed to remove and install those components safely.
Constructed from solid steel and finished in black, the AC1603 is a straightforward shop tool that belongs in any muzzleloader owner’s range bag. It is useful for breaking the rifle down for seasonal cleaning, swapping out percussion components, or freeing a fouled breech plug that has seized after extended use. This is the purpose-built service tool offered by CVA for their in-line muzzleloader platforms.
