As-arrived, after opening. Snuggly packed.
The goods
I didn't try this alone - had help!
The sight - until I pick up a handle or BUIS
The upper
The Mag catch together - that Youtube vid, and my daughter as holder, worked GREAT!
Trigger assembly
All done!!
Truth-in-lending. It's NOT together yet.
Rear Detent Spring LAUNCHED like a Saturn V. I have yet to find it.
(sigh)
