Looks to be a stock photo, as it appears to be the same photo whether looking at the stainless Mini 6.5 Grendel, the 1500 stainless 6.5 Prick, or the stainless 300 Win Mag.
exactly my thoughts also
as soon as someone confirms they should head to 6.5 Grendel forums where Jefferson is hokeypokeykid and advise stainless coming and they will sell like hotcakes so start planning on hinged bottom kit runs with silver finishes lol
happy to do so if someone gets that confirmation just let me know and will let him know
