Enhanced Power Hammer Spring

A: Yes this will work with the larger caliber AR-10/6.5 Creedmoor

A: Without knowing if hammer spring is installed correctly or what fire control group you are using it's hard to say. If hammer spring is installed correctly and using a fire control group friendly to this caliber and you are using Tula then that could be your issue. If using Tula you might need the enhanced plus firing pin we designed for this particular ammo to allow for even further protrusion since we notice many are still having light strikes with this ammunition: https://www.blackriflearms.com/AR-15-762x39-545x39-Enhanced-PLUS-Firing-Pin-for-Deep-Set-Primers_p_883.html

A: Yes it is compatible with an AR-15 300BLK build.

A: Yes its designed to be used with the 7.62x39 caliber also.

A: Our enhanced power hammer spring was designed to provide approximately 1 lb more energy than the mil-spec spring and that in conjunction with our enhanced or enhanced plus firing pin has worked successfully for the harder primers associated with 7.62x39 and 5.45x39 ammunition. We designed our own as we didn't like the feel of the trigger pull of the other manufacturers' spring and we designed them with full auto in mind. We will send you bulk pricing in an email.

A: Our hammer spring is not going to provide any more strength than the Wolf Hammer Spring. Can you send a picture of your hammer spring in your lower installed so we can take a look to see if we see anything out of ordinary to help you. You can use our Contact Us page to send us an email with a picture attached.

A: Yes you can use it in the 5.45x39 AR-15 platform

A: Yes you can use it in an AR-10

A: Just try upgrading to the spring. The enhanced firing pin can cause pierced primers in the 5.56 caliber. You can also contact us through our CONTACT PAGE at the bottom with a picture of your lower receiver where we can see the spring to see if there may be a incorrect hammer spring installation, this is the #1 common cause of light strikes on 5.56 when using steel case ammunition.

A: Yes they are full auto compatible. We designed them to be full auto compatible as we run full auto and use this enhanced spring for our own full auto rifles.
