I never really added anything to my LE6920 but I'm thinking of an EOTech and a BUIS now. Is the "F" marked FSB on my rifle taller than a standard sight tower or shorter? How does this affect which BUIS I buy? A friend has a Bushmaster M4A3 and is asking the same questions...but I'm under the impression that his is a different height. Sorry for the ignorance. I've been around for a good while on this sight but once I got my AR I haven't been around the AR side much lately. CMS |
| Colt's come with "F" height FSBs. I have rifles with "F" height FSBs, and rifles without "F" height FSBs, and my BUIS (Troy and MI), zero perfectly with either. One of my rifles is a Bushmaster, and everything zeroes fine. If your friend's doesn't zero out for some reason, he'll need to order the taller front sight post from Bushmaster. |
