Building an AR10

[Weber]

Nope, not one failure.

I'm using the lighter JP springs, and have not had to cut the hammer. I run that on all my AR's and have not had to cut any of them. I have heard others always cut the hammer down.

These are the springs.

Kewl. I noticed on my Bushmaster LR308 MOE when I was installing a RRA two-stage that the hammer spring was a different gauge wire than the standard AR15. So, I decided to use the original OEM spring with the new hammer.

The lighter gauge on the spring lowers the pull. Some guys like it lighter, others like a little more. It's all about shooters preference.
