The thing with epoxy is that the two halves don't do much on their own, so if some leaked into the breech section... etc, then it would need the other half to actually set, so you've got a better chance of not messing it upYep, is a unitec
Sheared at the thin black bit (the back), just above the threads and yep, the red part is the front/inner
And yep, the stuck part doesn't protrude from the gun and is probably about 4/5mm in
I was tempted to try inserting the front, didn't think of using epoxy (never used it before), with superglue and using it to unscrew the thing but the front is still in leeds so couldn't try it until i get back and i was worried about glue leaking over onto the gun threads or into the breech...
Or so I believe...
