The convertible two-cylinder system allows use of both .22 LR and .22 WMR. This example includes the Ruger .22 WMR fluted conversion cylinder in its red pouch, adding practical versatility for different rimfire loads.
Construction is all stainless steel with a satin finish across the frame and cylinder, paired with a 5.5 in cold hammer-forged stainless barrel. The 1:14 RH twist is well-suited to common .22 rimfire bullet weights.
Sights are straightforward and functional: a ramped black front blade and a fully adjustable black rear sight. Operation is single-action with Ruger’s New Model features, including a transfer-bar safety and loading-gate interlock.
The revolver uses a 6-round, fluted cylinder and smooth hardwood grip panels with Ruger eagle medallions. Two frame cross-pins identify the New Model lockwork, and the left-frame rollmark reads: RUGER .22 CAL. NEW MODEL SINGLE-SIX.
Made in the United States during the 1970s, this revolver aligns with an approximate ship year of circa 1978, reflecting the desirable late-1970s New Model production era.
