How much material are you guys removing when doing the flashing on the FSB?

Are you going completely flat on the front & back?

I'm using a pneumatic angle grinder, starting with 220 and working my way into emery type wheels. (Course,medium,fine)

I removed just the flash ridge, flat on front and rounded the rear. The photo makes the contrast in the parkerizing look more dramatic than it is, but the flash is completely smooth.

If thats all you did & it looks that good, then there's no reason to go any further than I have.
My OCD side keeps telling me to smooth over the sides as well to give it a sharper profile.
RBR doesn't give you a close up shot of the 601 & it looks like the sides have been smoothed flat to give it a flatter sharper profile.
Then again it could be me needing glasses.

I studied all the pictures of originals I could find. Some were ground down more. I think it was just a matter of the machine operator and the particular FSB. some FSBs had a more flat back or a rougher casting and needed more grinding. I sorted through my modest collection of FSBs and selected the one that had the finest details, mo molded in code, and a pleasingly rounded backstrap. Then I removed only the material that was necessary.

Remember, the 601 and early ARs had cast FSBs, which did have crisp edges and flats, unlike the later forged FSBs.

Yup, I should add that mine is on an XM16E1 clone. I wasn't trying to replicate a cast FSB, Just an early forged one. I have a thread on it some where.
EDIT: Thanks for finding my thread, 86HMMWV.

Here's your XM16E1 thread, SF.

I may do a test run at smoothing the sides with a surplus  A2 I have laying around.

Hey Frankenstien

The one you sent that I parked for you looked prety close to the original smoothed ones I have here. They had rounded faces front and back. On the ones I grind to mimic cast ones I grind them  thinner and flat, with as square corners as I can get.

If anybody tries to mimic a cast one. Be sure to use a FSB with lots of meat between the sight detent hole and the front face. And be careful how much you remove.
Guess how I know this!

Interesting you should bring this up. Here are some pics of an A2 I started practicing on, I'm doing it old school and using a hand file and steal-wool.
