Was it tricky to install?

I hate all those pins and springs that go sproing!

The manufacturer has very good illustrated instructions.
(He even gives you warnings for those step where springs and parts can go flying.)

I took my time and did a little fluff & buff on the trigger bar since I had it entirely disassembled. It took me close to 3 hours. I could probably do another one in less than an hour now that I'm completely familiar with the design and parts.
