Built specifically as a cap-and-ball companion to NAA’s .22 LR mini line, this revolver retains the familiar micro profile while using #11 percussion caps and 30-gr belted .22 lead bullets. The unfluted, five-shot cylinder is recessed at the nipples for proper cap seating.
The stainless-steel construction extends to the barrel, frame, and cylinder, with a matte bead-blasted frame and barrel paired with a brushed/bright cylinder and a polished knurled base pin (mixed stainless finishes). Dimensions stay truly compact at about 4.0 in overall length and about 5.1 oz in weight, with a 1.125 in barrel.
Operation is single-action only with a spur hammer. Sighting is straightforward, with a simple, minimalist arrangement in line with the NAA mini-revolver format.
The birdshead grip frame wears smooth, rosewood-toned panels for a classic look and secure purchase. A knurled, removable cylinder/base pin incorporates the factory bullet-seating tool, providing a handy on-gun loading aid for the included belted projectiles.
Manufactured in the United States, this Companion is cataloged under mfg part number NAA-22LR-CB. Companion percussion models typically carry a K serial prefix.
