FN 5.7X28 round

[Kelly Alwood]

This is the AR57 upper on a standard AR-15 lower receiver. This is the 10" SBR model with a 5.56mm suppressor on it.
Zero light signature. And more than quiet enough to shoot comfortably without ear protection.

This is the 5.7X28 against a Military Level 3 Kevlar vest.

[Kelly Alwood]

This is an FN FiveSeven pistol (5.7X28) with a .22LR suppressor on it. Listen to the difference.
You can comfortably shoot standard high velocity rounds with no hearing protection.
