Marine Tex

As mentioned on the parent page, I chose to repair the riser area below the ejection port to restore the "original" look and configuration to the rifle.

I cut the "cover tab" from the TN / BMP AR magwell and used this as the filler.

I used liberal amounts of Marine-tex:

The tab is thinner than the receiver, and so I put a second layer of Marine-tex over the top, like cake icing.  This was very difficult because I cut the riser "wide" in that the tab just barely touched the receiver edges. 

In hindsight, I would not cut as much from the receiver or use some ABS plastic and cut that to shape.  After I did all of this, I realized that I had plenty of ABS material from which to work... I have some ABS tool boxes and storage crates that I could have cut the material from.

Smoothing

I milled the bottom so it would be level with the top of the receiver.

I switched between a common wood file and an orbital sander with 220 grit sandpaper.  The sander worked surprisingly well. 

EPOXY DUST IS TOXIC - IF YOU SAND IT, WEAR A RESPIRATOR!!! 

Safety first - 'nuff said!

It took the RIT Dye very well... follow the link to this page to see the results!
