Q: Will this fit my Windham Weaponry src in 7.62x39?
A: Yes you should have no problems with fitment. This spring will fit any mil-spec AR-15 Lower.
Q: Will this help with 7.62x39 hard primers in an AR along with the enhanced firing pin?
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.
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?
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
Q: Do you have the 3 pack of these? Thanks,
A: We buy these springs in bulk from Wolff and then separate them out. We don't have 3 packs currently, but I'll look into getting them up today for sale in 3 packs and 10 packs. Thanks for the tip.
