Magpul Drop-In Complete Upper Receiver, 5.56/.223
This is a great upper. All of the parts are of the highest quality. We build these uppers and test fire them in house. We have these in stock and they are ready to ship.
TEST FIRE: Most other companies do not test fire their products, and if they do it is usually a "lot" test. We test fire each and every upper. We shoot three shots and do so in rapid succession. Test firing allows us to be confident that the upper we are sending you is ready to go out of the box. We do our test fires dry and recommend that you lubricate your upper prior to shooting it.
ALL PARTS ARE MADE IN THE USA.

Black Nitride/QPQ: This is an extreme case hardening process which turns the steel black and hardens the surface of the steel and extends the life of the product. QPQ stands for Quench Polish Quench. This process is now commonly used in the industry. Our Black Nitride products are coated by H&M who own the trademak, "Black Nitride".
