For Revolver shooters who have longer barrel lengths, this extension rod for the Race Master Muzzle Support
Assembly, add another 1.5” (32mm) to the length currently offered as the standard set. With this rod in place, the
muzzle support with the revolver adapter will fit barrels of up to aprx. 7.5”.
NOTE: This is the extension rod only! It does not include the complete muzzle support assembly, which is sold
separately.
Required for S&W 929
The original won't support long-barreled revolvers, so this extension is a must for 929 and similar revolvers. Not needed for pretty much any semi-auto.
