Machining an AR15 lower receiver

[Highpower]

Thanks guys. She's not perfect, but hopefully the next one will be.

The funny thing is other guys at the range will often come up to me asking about it, because they aren't familiar with the rimfire conversions. I always ask them if they would like to shoot it, and I've never been turned down yet.

And what is the one thing they comment on the most????
The nice trigger break? - No.
The accuracy? - No.
The smooth function? - No.

The serial number..... 0001
