First ever solution for suppressed VZ 58 platform while using supersonic ammo.
Developed for 12'' and 16'' variants of VZ 58 rifle in 7.62x39 & 5.56X45 NATO

These pistons are custom made  with smaller diameter head to bleed excessive gas and prevent abnormal wear / damage of bolt carrier group and receiver when not using subsonic ammo while shooting suppressed.

Works great on 7.62x39 platform with both Traditional and Flow-Through suppressors.

On 5.56X45 NATO platform Traditional suppressors preform great, set ups with Flow-Through suppressors required recoil spring to be cut down.

Made of 4140 steel and hard chrome plated.
