Century Arms MB47: 7.62x39mm Precision Semi Auto Rifle

There are rifles that earn your respect for what they do on the range, and there are rifles that earn it for how thoughtfully they’re built. As shooters who value precision, reliability, and sensible engineering, we evaluate firearms the same way we approach a mission: methodically. This piece breaks down the features, performance, and real-world applications of a modern 7.62x39mm semi-auto that aims to bridge classic cartridge performance with contemporary ergonomics.

CENTURY ARMS SHARPS MB47

Built in collaboration between Century Arms and Sharps Bros, the CENTURY ARMS SHARPS MB47 is a modern take on a proven platform. Right out of the box it ships upgraded with a suite of components chosen for durability and shootability, and it’s chambered in the 7.62x39mm cartridge — a round that remains relevant for both recreational shooting and practical field use.

Design & Construction

The MB47’s receiver is precision-machined from 4140 steel, a decision that pays dividends in longevity and consistent fitment of parts. The use of a chrome-lined barrel enhances corrosion resistance and eases cleaning — a practical choice for shooters who want a dependable barrel life without exotic metallurgy.

Handguard, Stock, and Controls

Rather than a basic factory package, the MB47 ships with a US Palm freefloat M-LOK handguard and matching pistol grip that promote modular accessory placement while keeping weight in check. The Magpul DT carbine stock provides a familiar, adjustable cheek weld and length of pull for a wide range of users. These choices reflect an emphasis on adaptability and ergonomics.

Trigger & Compensator

Trigger feel matters. The MB47 features Khyber Custom’s new flat-faced variant of the RAK-1 trigger group, which delivers predictable engagement and a flat face that many shooters prefer for positive finger placement and consistent trigger pull. Century Arms’ Chevron Compensator reduces felt muzzle rise and helps manage follow-up shots — useful in rapid strings of fire during drills.

Caliber: 7.62x39mm — Practical Benefits

The 7.62x39mm cartridge remains valued for its balance of moderate recoil, effective terminal performance at close to medium ranges, and widespread ammunition availability. For shooters interested in affordable practice without sacrificing meaningful ballistics, this caliber offers an attractive compromise. It’s especially well-suited to field-style shooting, training sessions, and applications where robust performance inside common engagement distances is prioritized.

Ballistics and Applications

Expect manageable recoil that allows for quick follow-up shots while still delivering heavier bullet impacts than typical intermediate .223/5.56 loads. The MB47’s chrome-lined barrel ensures consistent harmonics and corrosion resistance, which is an advantage when running bulk ammo or when cleaning intervals are stretched during extended use.

Field Ergonomics and Handling

From a handling perspective the MB47 is tuned for intuitive control. The Magpul DT stock, combined with the US Palm grip and freefloat handguard, yields a platform that feels balanced at the shoulder and responsive on the draw. The flat-faced RAK-1 trigger improves perceived precision, and the Chevron Compensator helps the rifle settle quickly between shots.

Accessories and Upgrades

The M-LOK handguard gives you clean attachment points for lights, sights, and rail sections without adding unnecessary bulk. The receiver’s 4140 steel construction supports routine upgrades and customization while maintaining a serviceable base for optics and backup iron sights.

Performance Expectations

On the range the MB47 behaves like a purpose-built semi-auto: reliable cycling, consistent group potential when paired with quality ammunition, and a comfortable recoil impulse. The one 30-round magazine included is generous for range days and drills, and the all-black finish offers a low-profile, tactical appearance without flash.

With a retail price of $1500.99, the MB47 sits in a segment where component quality and out-of-the-box usability are expected. For shooters who want a semi-auto platform that doesn’t require parts swapping to be competitive, that price point reflects the upgraded parts and assembly that come standard.

Who Should Consider the MB47?

If you’re a marksman who values solid manufacturing, aftermarket-ready ergonomics, and the utility of the 7.62x39mm round, the MB47 is worth a look. It appeals to recreational shooters, collectors seeking a modern take on classic calibers, and users who want a semi-auto that’s ready to run without immediate upgrades.

Comparative Value

Compared against entry-level builds, the MB47’s upgraded components — from Magpul furniture to Khyber Custom’s flat-faced trigger — justify the price for buyers who want fewer initial modifications. The chrome-lined 4140 receiver and barrel combination also signals durability that should keep long-term ownership costs lower.

Final Assessment

We respect firearms that start with quality parts and thoughtful assembly. The CENTURY ARMS SHARPS MB47 blends a rugged 4140 machined receiver and chrome-lined barrel with modern ergonomics like the US Palm M-LOK handguard and Magpul DT stock. Khyber Custom’s flat-faced RAK-1 trigger and Century’s Chevron Compensator improve control and follow-up accuracy, while the 7.62x39mm chambering gives practical stopping power with manageable recoil.
