All of our uppers have had 3 rounds fired through them. They will come with some slight marks on the BCG and charging handle, rest assured all parts are new. We do this for several reasons, 1) to make sure the upper passes our function test, 2) see number one. The upper will not be cleaned after the 3 round burst.
*Lifetime Guarantee covers manufacturing defects in materials and workmanship, regardless of the age of the product, but it does not cover normal wear and tear. Wear and tear is damage that naturally and inevitably occurs as a result of normal use.
The use of reloaded or remanufactured ammunition will void the warranty, due to the unpredictability of the standards (SAMMI/NATO) adhered to, since reloads of poor quality ammunition may not meet (SAMMI/NATO) specifications, may exceed limits, and therefore may be unsafe.
