Just put a quick 50 rounds through my new MPX SD today and it immediately put a smile on my face. An absolute dream gun.

Average of 1048FPS with cheap over the counter 115gr without issue.

Conversion process was painless and within the estimated time window.

Ronin Arms RA9-SD K 5.75" Ported Barrel

5/5

Being one of the more expensive conversions, I had some high expectations, and Ronin Arms surpassed them. I’ve watched/read several reviews of conversions from other companies and saw things like the a few supersonic cracks from 115s, leaving the standard cocking tube, no refinish, etc. The work and attention put into my gun was well worth the wait and price. They gave attention to the small details like lining the cocking tube up perfectly, clean welds on the SD cage to spec. As far as the actual shooting, this is the quietest, smoothest MP5 I’ve shot. I ran 300 rounds of 115gr with no issues, and thanks to their unique porting, it’s not filthy at all. Highly recommend.

Also, I would like to thank you and your team for the incredible work you guys did! After shooting the MPX last weekend for the first time since the modifications, I can confidently say it’s become my favorite gun—quite a statement considering my collection.

I truly appreciate all your help throughout the process.

Wishing you a great day ahead!

If you don’t absolutely LOVE it, there is something wrong with you.
Quality work resulting in superior performance. I would not hesitate to do this again, as a matter of fact I’m debating a second one.
Sound suppression is phenomenal, especially when compared to end of barrel suppression. Night and day; don’t want, just get it. You know the saying, buy once cry once.
