Wolff AR15 Extra Power Hammer Spring

This spring works great for my ar 7.62 x 39 that shoots old Russian rounds. It hits the bullets perfectly and is everything I needed.

Built an AR15 chambered in 7.62x39 for a customer during the test fire I was having soft primer strikes. I ordered this spring it was super easy to install and it solved my striking issues. Would definitely recommend if building a 7.62x39.

The Wolff spring is great. No issues firing steel casing rounds. Highly recommend for all ammo.

What to say... I bought a 7.62x39 upper and I shoot Tul Ammo and wolf. had several misfires close together. A co-worker told me about these springs, as well as enhanced firing pins... no more misfires.. Run through as fast as the trigger can be pulled.

Got my.part super fast... and got a sticker with their logo for my collection.... definitely recommend

I have a BearCreak 7..62x 39 that was unusable, until I installed this spring, now I have a fully functioning A.R. and steel-cased ammo is no longer a problem! Thank you! Armory Dynamics
