Q: I currently have a Geiselle G2S and the 7.62x39 enhanced firing pin. Would this hammer spring be stronger than the one from the G2S?

Asked by: tcc13c - 3/22/2021
A: We can only assume Geiselle uses a mil-spec hammer spring so in that case this spring would be stronger. We have not gotten any reports that Geiselle hammer spring having light strikes so if you are having light strikes please give us a call for troubleshooting.

Q: Is the wolf spring stronger or less stronger than the wolf hammer spring. I have a lot of failure to fire issues using the 7.62x39 wolf ammo. I have your enhanced bcg in them as well do not sure whats going on, the ammo thats dimpled good shouldve fired, I can put them in my AK 47 and they fire away no issues. Not sure what the problems are but I run binary triggers and update the spring and Firing pins from BRA, And have a POF Renegade, doesn't seem to matter. The gun was sent to POA, of course like a new car, they never had an issue, funny it fails to fire for me

Q: Will the Wolff extra power hammer spring fit a remington r 25 r 10 lower trigger assembly? Will it help to fire wolf ammo?

Asked by: Wayne - 6/27/2020
A: It should, but because we are not the manufacture of said product you might ask Wolff for clarification as they have the R&D behind their springs: https://www.gunsprings.com/

Q: Why can’t these be used with full auto or burst fire? Can they be used with a franklin arms binary? Guess I will find out... these hammer springs were the only thing that made my 762 39 ar reliable so I used it on the hammer on my binary.

Asked by: Podesta art - 6/20/2020
A: Good day. This disclaimer comes from Wolff Gunsprings and our guess would be it puts too much stress on the auto sear due to the strength of the XP Hammer spring.

Q: Will this help with 7.62x39 hard primers in an AR along with the enhanced firing pin?

Asked by: Lorenzo Mata - 3/8/2019
A: Yes it will; however most of the time all one needs is just the enhanced firing pin, but many want the Wolff as "insurance" but we always say you can test without the Wolff XP Hammer Spring if you have the enhanced firing pin, many times the enhanced firing pin fixes the light primer strike issues.

Q: will this fit an AR-15 chambered in a 7.62x39? I'm attempting to shoot tula ammo but it's not hitting hard enough to set the primer off.

Asked by: joey - 2/13/2018
A: This firearm part is for the AR-15 platform including the 7.62x39 AR-15. What's more important than the Wolff XP Hammer Spring to set off hard primers of x39 ammunition is an Enhanced Firing Pin which allows for further protrusion to set off the harder primers of the x39 ammunition.

Q: What's the reason for not recommending this for burst fire? Is there a reason it wouldn't work with a Slidefire stock?

Asked by: Jeff - 1/16/2017
A: That is Wolff''s disclaimer/recommendation, not ours. You will need to contact Wolff Springs about their recommendation on this spring: https://www.gunsprings.com/index.php?page=items&cID=2&mID=1&dID=79#491
