Yes.
If the non F marked FSB was on a M4/Carbine it would be an issue. However, on a full length, 20'' A4, it is most definitely not an issue and will NOT effect the accuracy of the rifle.

All about the lowest bidder on everything.
You are correct. Its dollars and cents, not dollars and sense.
I had been wanting an A4 version for years and when it came down to nut cutting time, it was down to Colt and BCM for me. FN makes great gear and i'm sure the FN15 would be no different, but i don't want an FN AR15, for the same reason i probably wouldn't want a Colt 'SCAR'.
Yeap thats why I went with bcm provides me with a familiar platform of a weapon but different brand that I honestly think highly for. I like my bcm more than the m4s and a4s I used in the corps.
Does anyone know the material composition of the BCM receiver extension? I wrote to BCM several times but they did not respond.
