RRA barrels use F marked FSPs?

[JesterRock]

Does Rock River Arms use F marked or F marked height FSPs on their barrels? I'm looking to purchase their chrome lined 20 Inch Standard Heavy Barrel Assembly barrel to replace the 20" barrel on my Stag Arms Model 4 20" AR15. My current FSP is F marked. Thanks for any information.

They use standard A2 front sights.

That's a bummer

Hmmm, I forgot, that might have changed.

See my post number 8 and 11 in the link.

My last RRA 20 flat top upper did have a F.

I don't know exactly about RRA, but using a standard height FSB with a flat top receiver is easily compensated for by using a taller front sight post.
