RCM Inc. was the first company to produce a silencer completely compatible with the factory HK MP-5 SD. We also make the SD barrel that is compatible with our silencer and the German silencer.
With the current climate of many more states making it legal to hunt with silencers this makes for a larger market for silencers and makes them easier to obtain for the consumer.
We have made the MP-5SD silencer in both .40 cal and 9mm. We have made many other silencers of numerous calibers and requirements. Feel free to contact us on your production requirements. We have the ability to design and manufacture one that's right for you! Minimum requirements dictate quantity's of 100 unless it's a model that we stock.
