Dirty Bird AR-15 Multi-Cal Forged Lower Receiver Review
About Dirty Bird AR-15 Multi-Cal Forged Lower Receiver
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. 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.

Didn’t realize it came with a rear takedown pin fitment pressure pin. Fits lower and upper snugly together.

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.
Great

Exceeded expectations, shipped out 3 days after order! Well put together (I used their assembly service). Upgraded the internal parts and trigger. Loved the assembly tool to choose different compatible parts
Pleased

The only real reason I’ve given this four and not five stars is the fact customer service was great but their people who contact the ffl dealer was lacking in speed and communication.

Fast shipping. Looks great with midnight bronze upper and handguard. Haven't been able to take it out yet. Fits nice with upper, bought them separately on sale. No issues with assembly.
