seeking USGI hammer and trigger blueprint

AR/M4 AR Technical Discussion

I want to measure the trigger and hammer I recently put in my first AR build. Does anybody have a CAD drawing or other file with measurements? A disconnector blueprint would also be great.

I did a search on http://www.3dcontentcentral.com/ for “AR 15 hammer” and “AR 15 trigger” and it seems they do have the 3D parametric file.

If you have access to SolidWorks (parametric CAD program) you can download the files & view them in SolidWorks to get the dimensions you need.

I hope I didn’t confuse you too much. Good luck! :slight_smile:

The dimensions I’m interested in would be easy to see in a simple pdf file. I don’t think I have the software to read the stuff you suggest. I’ll try and see.

Nope. It’s not going to work.

Thanks. That’s the kind of drawing I’m looking for. I just can’t find drawings for LPK parts.
