Meticulous Machining
We wanted perfection, so we teamed up with the folks at DRG Manufacturing Industries. DRG Manufacturing is one of the industries’ best kept secrets. And while we’d love to keep them all for ourselves, we can’t talk about the quality of this lower without giving huge props to their team. Lots of companies are known for their creative vision, others are known for their unwavering attention to detail. DRG does both, and they do it very, very well.
Made in the USA
Backed by the Dirty Bird Limited Lifetime Warranty

Dirty bird lower
Excellent experience. Quality product
USGood lower with a plus
Didn’t realize it came with a rear takedown pin fitment pressure pin. Fits lower and upper snugly together.
USGreat lower
Purchased this for a custom build. Tolerances were great and I really liked the way it fits the upper I purchased separately. OD Green is getting tough to find and I was excited to get this lower in the color I wanted. Shipping was abysmally slow but I am happy with the part I got.
