byf Toggle Chamfers

[sheepherder]

...or bevels...whatever...

I bought this receiver/toggle train from a respected (and feared) forum member a year or so ago, intending to mount a 4 3/4" 9mm Tikkakoski barrel on it...I finally got around to it Sunday...Barrel is all mounted and timed and headspaced...

...But as I was doing this, I was reminded of some of the discussion surrounding friendlyfred's Spandau Luger toggle...

Look at these chamfers/bevels [whatever] on this byf toggle...Have you ever seen such extended chamfers??? The toggle looks positively skinny...

And the bevels/chamfers are rounded, not a 45º bevel/chamfer...

It doesn't look altered...

...Just...weird...

Comments???
