Centurion Arms MK11 7.62 Billet Receiver Set - MK11-B-762-SET

The Centurion Arms MK11 7.62 Billet Receiver Set is designed for an SR-25 pattern semi-automatic rifle. The MK11 receiver set from Centurion Arms is designed to have all the features you need and none of the useless design aesthetic that drives up prices for no other reason than to stand out at the range. Machined from 7075-T6 aluminum and type III class 2 hardcoat anodized to military standards for a long service life of reliable use. The lower features a flared magazine well that isn’t so large as to get caught on gear when you are carrying it but will greatly increase your reload speeds. The enlarged, integrated trigger guard allows for use of gloves and eliminates a potential weak point. All sharp edges have been de-burred by hand for a smooth premium finish and all dimensions are inspected for accuracy. The Centurion Arms MK11 Stripped AR-10 Receiver Set is what you need to start your next build. Features: Knights Armament pattern CNC machined from billet 7075-T6 aluminum Class III Type 2 hardcoat anodized black Compatible with Mil-Spec parts Flared magazine well Integral winter trigger guard Receiver tension screw Fully de-burred by hand Dimensional accuracy inspected 90° safety selector markings Multi-caliber Slick side upper Picatinny flat top Made in the U.S.A. Weight Lower: 9.5 oz. Weight Upper: 11.3 oz. Another feature of the billet AR-308 lower receiver is the rear tensioning screw that takes out any wobble between the upper and lower for better accuracy and a more solid feel. The safety selector pictograph markings are designed for 90° safeties and is compatible with ambidextrous safeties as well as other Mil-Spec and aftermarket components. The upper receiver features a slick side design without the forward assist. All components, material, and packaging are made in the United States and the overall weight of this set is 20.8 ounces.

Dirty Bird AR-15 Multi-Cal Forged Receiver Set

Dirty Bird Industries AR-15 Forged Multi-Cal Lower Receiver: 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. Dirty Bird Industries AR-15 Stripped Upper Receiver: The Dirty Bird Industries AR-15 Cerro Forged Stripped Upper Receiver is precision machined to M16/M4 Mil-Spec using top quality Cerro Forgings. They are then finished with a uniform Mil-Spec Type III hardcoat anodizing. These units are quality checked throughout the process to ensure consistent quality from unit to unit. Builders know that not all mil-spec forged upper receivers are created equal. Sub-par forgings suffer from pitting and structural defects, poor anodizing can result in a purplish or chalky finish that doesn’t last and sloppy matching can result in mis-sized lugs, burrs or other machine marks. You have Dirty Bird’s word that these uppers will be free from excessive pitting, machined to spec and finished with quality (not purple or chalky) hard coat anodizing. Features: 7075-T6 Aluminum Cerro Forgings M4 Feedramps .250 takedown pin holes Port Door (Dust Cover) and Forward Assist not included 100% American Made Dirty Bird Industries’ Limited Lifetime Warranty
