Lower Receiver, Mk4/AR15, BLEM

When the goal is pure function without a focus on aesthetics, pick up one of our blemished Mk4 AR15 stripped lowers. Each blemished AR15 lower may exhibit some cosmetic imperfections but remain functionally unchanged.  Photos shown are not representative of every blemished lower available. All blemished lowers come cerakoted, but the color assortment will vary.  Most will be solid colors, but some may come in a pattern or multi-color variant.  This is an instance of, “You Get What You Get” as all orders are randomly picked from available blemished stock.

Blem lower orders are not eligible for cancellation or refunds. Each blem lower features dual CMMG engravings on the magwell.

Lifetime Quality Guarantee
