Wolff Extra Power AR Hammer Spring

Wolff Extra Power AR Hammer Spring

(5 reviews) Write a Review

Hammer springs available in factory strength and extra power. XP hammer springs improve common ignition problems when using hard primer ammunition.  Note: For use in semi-auto models only.  Not for use in full auto or burst fire models.

Faxon Factory Note- This hammer spring is recommended for the 7.62x39 kit. The increased energy is required for reliable detonation on some surplus ammunition. Those who ordered the caliber with their rifle will receive their rifle with this spring installed. It is not included with the ARAK-21 upper receiver only.

    Worked to fix fail to fires on steel ammo but at the cost of an 8.5lb trigger. With some work i got the trigger down to a safe 5.5lbs so it does come at a cost but product does work.

    Had issues with steal cased ammo light strikes on my 7.62x39 ARAK. This spring resolved my issue 100%. Went through 160 round of Tula with no failures, before was about 50/50 at best.
