Dirty Bird AR-15 Multi-Cal Forged Lower Receiver - BLEM - D014-1B
Out of stock
The Dirty Bird Industries AR-15 Forged Multi-Cal Lower Receiver is a great starting point for your next build.
Start with Quality Forgings
All MCF-A lowers are machined from top-tier 7075 Aluminum Forgings from Cerro Fabricated Products. It is a common misconception that all forgings are created equal. Cerro Fabricated Products has been a leader in precision forging, machining, heat treating and more since 1915.
Meticulous Machining
We wanted perfection, so we teamed up with the folks at MVB Industries. MVB, best known for their innovative ARC-X PDW Stock, 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. MVB does both, and they do it very, very well.
A Quality-Control Centered Process
You’ll notice that in addition to ATF issued serial numbers, all of the lowers feature a unique identifier machined near the pistol grip interface. This is for tracking each individual unit throughout the production process. This added step allows QC staff to trace any potential quality issues back to an exact machine and a given batch, no matter how long it has been since that unit was produced.
Practical Improvements
It is one thing to add features to a battle proven design that is over 60 years old. There are some pretty crazy lowers out there, but are they practical? Do they sacrifice reliability? Do they make the lower more difficult to service or upgrade?
Self-Adjusting Receiver Tensioner
The MCF-A utilizes a spring-loaded plunger to reduce slop between the upper and lower receiver. No more tension screws or accu-wedges.
Lower utilizes oversized roll pins. A couple of these pins will be included in each lower purchased.
Made in the USA
Backed by the Dirty Bird Limited Lifetime Warranty
*Black color is type 3 hard anodized per mil-spec. Other colors will be Cerakote.

DIRTY BIRD IS THE BEES KNEES
I LOVE MY DIRTY BIRD LOWER. I use this for my 9mm build with the EndoMags and it is just butter. I bought the BLEM version, and to be honest I couldn't find any blemishes at all. The receiver is really well made and within tolerance to make your install a breeze. I wish they had more of these in stock because I am now hooked to this brand.
USA dinged up Dirty Bird
Part was excellent, good deal on shipping. So, what was the blemish? The bottom of the buffer retainer detent hole didn't get anodized.
