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.

A: Yes the spring is comparable to Wolff Spring, but designed it for full auto use since that is what we run. We run our Enhanced Spring and Enhanced Firing Pin on all our 7.62x39 rifles. When it comes to binary triggers we have seen some customers continue to have issues. If you have issue with enhanced spring/firing pin with a binary we suggest contacting your trigger company and explain your caliber and setup to see if they have a heavier trigger spring.

A: It could but the first thing to check is to make sure your hammer spring is installed correctly. Most times people who are having light strikes their hammer spring is installed incorrectly. If you are unsure you may reach out to us under our CONTACT PAGE and send us a picture of your hammer spring installed.

A: You will need to check with the mfg of your drop-in trigger.

A: Picture is the same as one picture will represent both springs as both springs look the same so no need for two different pictures. Color may vary slightly but that would be washed out in photo editing. Our spring was designed with less pull and it has a nicer crisp pull. We also designed ours to run full auto for those customers that have select fire.
