- n. A lever behind the trigger guard of a rifle
Sorry, no etymologies found.
If you have a spring gun, it is either a breakbarrel, an underlever or a sidelever cocking mechanism.
It opens by squeezing an underlever-- extremely smooth and ergonomic.
I use a .22 underlever for rabbit & squirrels and find that 25 to 30 yards is about right for a 12ft/lbs airgun.
Also what is best, assuming .22 for bunny, break barrel, underlever or CO2?
