note that they are very careful on their wording that those are not truly dragoon mosins. they are dragoon era mosins. during the war, or just after, these "older" guns were updated to the more modern 91/30 sights (front and rear) and sling swivels.
These are what are referred to as ex-dragoons, or updated dragoons. these are much easier to find than a real dragoon. It took me over 3 years of looking before i found the dragoon i have. the ex's are cool too, but nowhere near as rare, they usually bring a 10-20% premium. If you put one next to a 91/30 you will see that the ex-dragoon is slightly longer as shown in my pics above.
any mosin questions, let me know. im up to around 25 of them now.
RIP Mark 1977-2005 I miss the hell outta you bro.
