    ikibob29,

    I'm thinking we have a failure to comunicate. Either you are not writing reading or I am not able to read writing!

    Go to www.e-gunparts.com/ & check for a schematic/parts diagram.
    Once you have a parts list & schematic of your gun (by the way, you didn't hold the gun close enough to the computer screen for us to see which gun make & model we're talking about) your questions will be answered.

    Also, most makers will have an owner's manual avalible that also will have a schematic & parts list. Google your make of gun & see what is avalible on-line.

    If you are not able to locate a parts list & diagram, post your make & model; I'm sure one of our forum members will help out.

    The term sear is generic to the lockwork or firing mechanism of any non electric gun but sear lever isn't and may be nomenclature assigned by a maker to a specific gun part.
    There are disconnector levers as in the M-2 Carbine and trigger bars and trigger levers on double shotguns and Browning machineguns but I never came across the term sear lever.
    Do you have a specific gun in mind?

    There is a sear lever on automatic weapons that is used to engage and disengege the sear. The M14 has this lever as part of the trigger, the carbine although complacated has a arm that disengages the sear and I am sure that there are others. If you are working on a rifle and would post the manufacture and model number someone her might be able to help you.

    Simplifying, in any gun the sear is the part of the trigger mechanism that holds the hammer (or striker) back until the trigger is pulled.

    Pulling the trigger releases the sear and fires the gun.

    The sear lever, then, is a lever connected to the sear.

    Now, as to where the sear is, and how exactly it works is going to vary from gun to gun. Some guns can actually have more than one sear.

    The sear is one of the most critical parts of a gun, because motion of the sear is what causes the gun to fire.

    People spend a lot of time and effort working on sears to try and improve the trigger pulls of guns. For obvious reasons, you shouldn't try to modify the sear of any gun unless you know what you are doing because if you don't its very easy to mess up a sear and render a gun unsafe.

    This image shows the sear action of a 1911 pistol. The sear is the grey crescent-shaped part that connects the end of the trigger to the hammer.

    Edit: Thanks Jeff (below).

    To further answer the question, on many semi-automatic pistols (including the 1911), the little metal plate the back of the slide that holds in the firing pin and firing pin spring is called the "firing pin stop".

    This is a totally different part than the sear.

    You can remove the firing pin stop to get access to the firing pin and firing pin spring, if you need to clean the firing pin channel, or change the spring or pin.

    In the animated image above, you can see the firing pin stop as a vertical dark line that crosses across the base of the firing pin right where the hammer strikes it. Its cutaway in the animated image.

    This image of the 1911 firing pin stop being pulled out may help:

    And you can put the sear in a M60 MG backwards with some interesting results.

    bean,

    Could you be a little more clear?
    Seriously, that's an answer that even jeff can understand!

    Are you thinking of a specific gun - such as the Browning High Power?

    People here try to answer questions in good faith, but you need to do your part and submit an intelligible question. Your question is unintelligible.
    While some manufacturer may have called a part "sear lever",it is not a universal term and there is no such generic term as a sear lever.
