Frequently Asked Questions

What are the best modifications for suppressing an H&K MP5-K PDW?

For optimal suppressed performance on an MP5-K PDW, install an 80-degree locking piece to slow the action and use the H&K 'Gray' extractor spring for enhanced durability. These modifications help manage increased back pressure and ensure reliability during suppressed fire.

Why is the MP5's roller-delayed blowback system good for suppressors?

The roller-delayed blowback system keeps the bolt locked longer, allowing chamber pressures to drop significantly before cycling. This means more gas is directed through the suppressor, resulting in a quieter action and less gas blowback for the shooter.

What is the OSS RAD 9's 'Flow-Through' technology?

OSS RAD 9's 'Flow-Through' technology vents expanding gases forward through the suppressor. This design reduces back pressure and bolt velocity, minimizing gas blowback into the shooter's face, unlike traditional baffle suppressors.

Which mounting system is preferred for the MP5-K with a suppressor?

The iconic Tri-lug mounting system is strongly preferred for the MP5-K with a suppressor due to its quick-detach capabilities and secure lockup. While direct threading is an option, the Tri-lug offers superior convenience and reliability.
