HK MP5KSD Barrel - 9mm - 4.89″- Threaded 18x1

HK MP5KSD Barrel - 9mm - 4.89″- Threaded 18x1

The RCM HK Style MP5 SD-K Barrel measures 4.890 inches in length and is constructed from 41v50 cold hammer-forged steel. It features a salt bath nitride finish throughout. This barrel is designed based on the factory profile but is shorter and has a unique twist on the ports. This design increases the flow rate through the ports, which, when combined with the RCM K Suppressor, effectively reduces blowback and lowers sound levels.

*THIS WILL ONLY WORK WITH THE RCM 8″ SUPPRESSOR*
