Description

Additional information

This is the ROHM RG Model 66 mainspring guide rod, for Röhm’s single-action .22 revolver.

The guide rod runs inside the mainspring in the grip frame, holding the spring in line as the hammer works against it. Röhm built the Model 66 at Sontheim an der Brenz and, after the Gun Control Act of 1968 closed the import route, at the company’s Miami plant as RG Industries. Guns carry either marking and often both.

Many Model 66s shipped with a pair of cylinders, one in .22 LR and one in .22 WMR, which is what the M designation refers to. The same rod serves either.

Included: Mainspring guide rod only, the exact part pictured.

Fits:

Röhm RG Model 66 single-action revolver, .22 LR
Röhm RG Model 66M, the .22 WMR and dual-cylinder version
Guns marked Röhm GmbH Sontheim/Brz. or RG Ind. Miami Fla.

Does not fit:

Röhm double-action revolvers — RG-14, RG-23, RG-31, RG-38 and the rest of the swing-cylinder line
RG-15, RG-16 and RG-17 derringers

Fitting: Have the revolver checked and function-tested on empty chambers after fitting. Confirm the hammer falls fully and the action returns each stroke.

Please note: Buyer is responsible for verifying correct fit for their specific firearm. Installation should be performed by a qualified gunsmith. Please review all photos, as they are part of the description and show the actual item you will receive.

Condition: Used, with the dark factory finish largely intact and an even grey cast over the flats. The rod is straight down its full length with no bend, twist or set. The hooked head is crisp and unrounded, the step at the shoulder clean, and the hole near the tail round and unwallowed with no elongation. Light scuffing overall. No rust, pitting, cracks or peening.
