Montgo-9 (Black) BLEM


Our standard upper with a scratch or two (aka Blemished 9mm upper)

Sometimes the new guy scratches the receiver. The mail man dropped the box, or the coating just looks a little funky. Although this in no way affects the performance of the upper, visually it isn’t acceptable for a retail sale.  This is a great option for anyone looking to Cerakote or rattle can the upper to start. Save a dollar and purchase a blemished 9mm upper while we have them in stock. Blems, Scratches, and dents will vary but in no way will affect its ability to run.  We run these sales only when have enough collected parts so grab it while you can! Warranty still applies!
