SHARPS BROS. MILLED AK47 RECEIVER 7.62X39MM MB47
The MB47 is patterned after the original milled Bulgarian receivers but, with the added feature of an integrated AR buffer extension. Each 2 pound receiver is machined in Sharps Bros Utah facility from a solid 15 pound block of US sourced 4140 steel, then heat treated to an RC41 hardness. The receiver is compatible with any milled AKM parts kit or any standard, stamped AKM parts kit. **Minimal fitting may be needed with the top cover & safety for the stamped receiver kits. This receiver also will work with both barrels designed for milled or stamped receiver kits. The barrel must have a 23mm trunnion journal and, the parts you populate onto that barrel must be for/from the type of kit you are building(stamped or milled). **If you have a stamped kit and a stamped barrel profile barrel, with 23mm barrel journal, that will work. Or if you have a milled kit and a milled barrel profile barrel that will also work.
