FeedsTheNeed Posted August 26, 2022 Report Share Posted August 26, 2022 Help appreciated in identifying these two items: One select fire lower assy. HK33 or MP 5? A3 stock assy Hk33 or MP5? Only markings I can find on stock are "II" as shown in pic. Thanks to all! Quote Link to comment Share on other sites More sharing options...
Side Arm Sams Posted August 26, 2022 Report Share Posted August 26, 2022 Both are 93/33 specific but both can be used for the MP5 as well. Jim Quote Link to comment Share on other sites More sharing options...
mattnh Posted August 27, 2022 Report Share Posted August 27, 2022 The SEF lower can be used for HK53/93 (since it currently contains a .223 ejector lever) or in an MP5 (if you swap out the .223 ejector lever for a 9mm ejector lever - trivial to do if you have one). That A3 stock contains a buffer - it is used for non-buffered 53/93 bolt-carriers. These aren't all that common (ie pretty valuable) compared to a run of the mill MP5A3 stock. A typical MP5 stock just contains a rubber H-buffer. Quote Link to comment Share on other sites More sharing options...

Got Uzi Posted August 27, 2022 Report Share Posted August 27, 2022 The lower housing is the give away for it being an HK93/33/53 given it is marked 0-1-25. Most likely was part of a Maylasian demil from years back. I’d be interested in these items and the mags we discussed, if/when you get time to discuss.
