Works perfectly.

I have not taken these to the range yet, so I have not used them yet. The quality seems good. I disassemble magazines when I get them to check them over and treat the internals with clp. Everything came apart and went back together as it should. I would buy these again without hesitation.

I like the magazines and work the best for my MAC5K. I do have trouble with magazines being sticky when removing them. I have to work at it to remove them. I always have to remove the coating with a sanding block. Not sure if it’s the mag well. Please let me know. However I will always purchase MAC magazines

Easy ordering, very fast shipping, magazines are on par so far with HK MP5 magazines once broken it , they are a little tight when new but i would rather have them tight instead of floppy or sloppy.

Since the magazines that came with my new MAC5 were 100% reliable, buying more was the obvious choice. Now that I have 5 mags that run 100% it saves time at the range.

Purchased 2 additional magazines for my MAC5. No issues worked as good as the two that came with riffle. Will purchase more!

Excellent quality just identical as originals, have you used it works great. I will be ordering other items from SDS..

I have 10 of these mags all function well fit and finish is A+ they look great! As of early 2025 the mags are laser engraved on the lower side near the floor plate end; both left and right with Bigger MAC logo 9X19MM 9JPQ6 in 3 lines. The bottom line is a US Govt Cage code to identify SDS IMPORTS LLC as a federal contractor located in KNOXVILLE, TN, a primary naics of 423910, cage 9JPQ6, and UEI HT53UTN9W455

They work and fit perfectly
