For what its worth, I looked a long time to find mine for my latest build to celebratete the death of the LGR!!
It would seem that NEA has shifted much if not all there resources toward their AR line of products.
As a result supplies of their 858 accessories and kit are dwindling and getting harder and harder to come by.
For what it worth I have had both NEA and BC extended bolt catches in the past and I ended up going with the BC Extened Mag and bolt release set.
If your still looking, The Calgary Shooting Centre had one NEA extended bolt catch left when I was there on the evening of Dec 11. (I took their second to last NEA ambi selector!!)
While both will work, my preference at this time is for the BC Tactical items.
While a bit off topic, I also just ordered and received my BC tactical hand-guards. While I have not installed them yet, I really like what I see.
Think KAC RAS for the 858 platfrom.
There are a couple of minor annoyances from BC tactical.
First is that they only sell there extextended mag release and extened bolt catch as a set, (they can not be purchase individually)
Second the BC tactical handguard set come without the upper handguard cross pin, and you must use the one from your existing hand guards and swap out the pin.
Its no big deal, and I undesstand why they have done it this way, but both are still a PITA
Any how these are just my thoughts.
