About Us

Top Notch Top Ends is Firefighter and family operated. We have been open for civilian sales since 2010. All TNTE uppers are custom built using exacting tolerances by highly trained armorers. Your receiver and barrel are torqued to a spec of 55-65 +/- for best accuracy. Then your feed ramps and chamber are polished and de-burred. All uppers are checked for proper head-spacing and test fired to ensure reliability. Beware of sellers who refuse to tell you where their parts come from because all uppers are not created equal. We use only Milspec or higher quality parts for your upper. TNTE uppers are built with professionals in mind, we go through them with a fine tooth comb to make sure when you need it most it will be there for you. Feel free to contact us for quotes and to inquire about our Military, Law enforcement, and FD discounts or call us at 262.749.1370. Our stripped custom uppers are covered by a one year warranty. Complete uppers with bcg and charging handle have a limited lifetime warranty.
