There's one thats been on the EE on ar15.com for months. Its got a tube extension, mesa shell holder, enlarged bolt release (not sure what brands), a few hundred rounds through it, 2nd owner, and he was asking $1850. Still not sold AFAIK
I tried posting the link here but can't due to low post count. Google "site:ar15.com beneli" and yes "beneli" is intentionally misspelled in the title (might be why nobody can find it).
EDIT - My bad, its not an actual M1014, just an M4 with the collapsible stock. NEVERMIND
