Solid construction and nice finishes. Nice weight to it and seems very sturdy. Nice that it includes the front sight post. Would recommend any time. Also shipped very fast. Optics planet never disappoints

This sight base comes complete with sight post, spring, detent also with sling loop attached. This is for virgin barrel assembly and must drill for tapered pins. Seems mil spec and matches the nitrate barrels.

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.

It’s a good sight, the only problem with it you have to drill holes to get it to fit your barrel. The sight does not come pre drilled. You will have to take it to a gun shop for them to drill and mount to gun, unless you have the proper tools to drill your own holes

This front sight is not ready to mount. No set screw or holes for the mounting pins. It appears to be well made but it’s going back. There is a hole above the sling mount but it’s not tapped and there’s no access for a set screw.
