Yep , it could be that to . But then this wasn’t advertising , but what the original poster was told when he called them up .
I cold also see them using a different harder tang and maybe even hook , on conical barrels then on RB barrels . A few hours reading internet forums about insanely high conical loads ?
Not to mention in this day and age all it takes I one person with an issue and suddenly the internet is flooded with people and their opinions. No mater for right or wrong ..
that’s one of the reasons they changed their adjustment screw on their set triggers
.
The other issue is if the tang is hand fitted . Im not saying it is . Im not saying it isn’t . just raising it as a consideration .
I have fitted alot of standing breech setups through the years . both forged and cast . there is allways fitting involved , if you want the two to mate properly .
Thus the tangs are then , for the most part not capable of being enterchanged.
Now if it were me . I would buy the barrel and the tang as they suggested . Then check it out for
Yourself . Try the barrel with your existing tang and see how it fits . If the tangs are hand fitted then you will know right away .
If the tang is harder or not , probably wont be as easy to tell ..
Then if you decide nothing is actually different and they charged you extra , send the tang back and chalk it up to advertising hype
