I can get my new 5.45x39 AR to fire. It hits the primer and dents it but not enough. Man these primers are solid! I tried a couple springs and no go. So what the strongest out?

Deadon,
Check the hammer angle hitting the firing pin it should be near 90 degrees also Check your firing pin also, could be filled with cosmoline. I don't have it handy (dimension) but you need to check firing protrusion.

The 5.45x39 upper I bought came with a hammer spring.

i have a wolf XP hammer spring in my gun and it works perfectly.... the standard springs as you know ,dont have enough force to ignite the primer consistently..

Just wanted to update this. Installed the Wolf spring and BINGO all is great! Thanks guys, this is a awesome little rounds and you just cant beat the price. Its nice to be able to shoot it out of a AR.

Yeah, I finally got my 5.45 upper built, and I need to finish building the lower tonight. Mine came with the extra power hammer spring, but I was waiting on a few other parts. I used the upper on a regular lower, and I ran into the same problem. I have more wolff springs coming, so I should be able to upgrade some of my existing lowers as well. The one for 7.62x39 especially comes to mind...

I thought I needed an extra power spring. Putting one in helped, but didn't entirely fix the problem. Take a look at this thread about my issue:

Popped Primers in x39 AR (Wolf Ammo) (http://www.calguns.net/calgunforum/showthread.php?t=497925)

If your problem continues (or resumes) check the firing pin channel for tiny brass disks. Then check your spent cases for some with holes in them. If you find any of those (brass disks in FP channel, or round holes in primers on spent rounds) you are likely getting "popped" primers. About $12 worth of gunsmith to the bolt face fixes the issue.

Primers looked great. It was just the stock AR hammer spring that was the problem.

ive never had issues with the milsurp ammo, although accuracy is better i hear.
