USMCSGT0331, thanks for those pics, that's a crazy collection of Mk 13 stocks, and it looks like you have take-off bolts for many of them too(!).

One question/favor: In the 2nd pic of the left side of stocks, the tan stock 3rd from the top (in the 2nd column) appears to have 4 separate 'dope' cards attached to the side of the stock. My assumption is that all these rifles when in service used the Mk 248 Mod 0 ammo (190 SMK bullet), and thus I am curious about any details re dope cards on that particular stock - so any close-up pics of that particular stock's dope cards would be appreciated. It would be interesting to see if a different dope card existed for a suppressed Mk 13 (ie, Mod 3) vs an unsuppressed rifle (ie, Mod 0), or if that stock was perhaps used for testing the later Mk 248 Mod 1 ammo (circa 2009-10), or perhaps another ammo type of 300 WinMag ammo?

Fwiw, attached is the dope card on the stock I got from you last year. It shows a (presumably) 100 meter zero, with drops out to 1200 meters, which was the 'official' max effective range of Mk 248 Mod 0 ammo of the era, but the later Mk 248 Mod 1 ammo has an official effective range of 1500 meters, hence I was curious if any dope cards on that one stock got out to 1500, etc.

(Also, just curious if any Mk 13 Mod 0/3 stocks you have, or sold, had the last 4 digits '**3981**' or **4378**' - a long shot of course, but have to ask...)
