SHARPS MB47 MLLD AK RECEIVER 7.62X39
Sharps Bros MB47 MLLD AK Receiver, 7.62×39
So you want a milled AK receiver with real strength behind it. This is it. The Sharps Bros MB47, machined from a solid block of 4140 steel. Milled, not stamped. Built for 7.62×39 AK builds.
This is not a stamped sheet metal receiver. Also, this is not a budget casting. First, this receiver starts as a 15 pound block of US-sourced 4140 steel. Next, it’s machined down to its final 2 pound form. Finally, it’s heat treated to RC41 hardness for real durability under recoil and use.
Is this receiver a complete firearm?
Yes. So this matters before you order. This is a 100% complete, serialized receiver. Therefore, it must ship to a licensed FFL dealer for transfer. You cannot have this shipped straight to your home.
What parts kits work with this SHARPS MB47 MLLD AK RECEIVER 7.62X39?
Most stamped or milled AKM kits, with some fitting expected. So this receiver patterns after original milled Bulgarian designs. Also, it includes an integrated AR buffer extension, which is a unique feature for stock options. However, expect some fitting work, especially around the top cover and safety, when using a stamped kit. The barrel journal is cut to .9065 inches after heat treat, so measure your barrel before final fitting.
Why choose a SHARPS MB47 MLLD AK RECEIVER 7.62X39 over a stamped one?
Strength and rigidity. So milled receivers come from a solid block, not bent sheet steel. Also, this typically means less flex under stress. First, that can mean better long-term durability. Next, milled receivers often command more respect among AK collectors, since original milled AK-47s set the early standard for the platform.
What’s the integrated AR buffer extension for?
It expands your stock options. So instead of being locked into standard AK stock mounts, you get an AR-compatible buffer tube interface. Therefore, you can run AR-pattern stocks, including adjustable and folding options, on an AK platform. This is a notable upgrade over a standard milled AK receiver.
Who is this receiver best for?
This fits AK builders who want serious strength and modern stock flexibility. So if you’re building a 7.62×39 AK and want a milled foundation with AR stock compatibility, this is a strong pick. Also good for collectors who appreciate the milled-receiver heritage, and for builders willing to do some fitting work for a stronger end result.
