80% 9mm lower

[Rthomas]

Would anyone here know why we would have to epoxy a part of the polymer lower for the lower. E P ARMORY EP80-G CLOCK STYLE 80

Appears the extractor ejector is steel, and for whatever reason couldn't be cast into place in the polymer, so needs to be added after machining out the pockets?

See this (metal) 80% lower for an example of how it'd normally be attached with screws:

I’m not sure and this is my first build . So I’m hoping for some insight . Thanks

Probably because if it came installed it would be >80% lower?

Sorry

I found it much easier to use an AR15 lower with the TorkMag glock magwell adapter. It has the ejector built into it. Pretty cool.

INSTALLATION OF THE EXTRACTOR:

1. Use heavy duty epoxy and set extractor in place
2. Align the extractor in place and draw line on extractor. Apply epoxy, install the extractor. Allow curing time.

Get a BCG with the M4 style extractor and you can just leave it out. I had to take it out of my lower (not polymer) so the drum mag would lock in.
