sear
That is the part which releases the hammer or striker to discharge the gun.
There is no best place to buy a gun sear since each state sells different guns and ammunition. The best options might be a local gun store, a sporting goods store, or a pawn shop.
It depends on which brand and model, but in general, it is inside the slide near the rear of the gun.
Do you mean Sears not sear. It would help if you stated the model number. Without that it is not very easy to answer your question, if it is a SEARS model. But I can give you this bit of information. It was either made by Daisy or Crosman air gun company. I suggest you do a search for "Air gun Repair" in Google and locate someone near you to repair your pellet gun.
The solenoid can refer to two things: The solenoid on electrically assisted sear tripper markers (like a Tippmann with electric trigger) the solenoid is an electro magnet that moves a long pole that trips the sear that fires the gun. A solenoid valve is an electronically controlled valve (like on a Smart parts ion, or any gun you don't have to cock) it uses electric current to open and close.
Because the electronic trigger runs on a battery, and without it, the sear will not depress and the gun will not fire. The only gun that can fire when its battery out is the Tippmann x7 phenom, and only in semi auto mechanical mode.
A homophone for "sear" is "sere."
If you are asking how to fix it: Unfortunately unless you can glue or seal it it, the gun will not work without the Black sear pin. You may have to buy a new receiver half.
the only legal way is to put in a registered class 3 auto sear
