Ignore the other fools reviewing this - CMMG F Marked Front Sight Base Assembly, AR15

I recently purchased a friend's cmmg FSB just like this one that he got off optics planet. I saw a few reviews about how the product has no holes. When you do a fixed sight build, the pins must be put into the individual build and drilled. Yes, you should have a professional gunsmith do this, and you should've known this. This is not an uncommon thing, I've seen countless new BCM, Cmmg, Retro rifles, etc FSBs. Guess what? They are all like this because that's how FSB builds work. So don't buy this product and act shocked that when you went back to the original 1960s sight system for the AR that suddenly it's not as easy as a pair of freaking flip up sights.
