| Is it better to mount the front sight on the gas block or a free floated rail? |
| Personally with a flip up front buis I like to install it on the free float rail since I only have buy one length. A gas block buis is a different length than a rail mount buis. I would fear that a clamp on or set screw gas block would work loose before my rail would but I don't have experience with this yet...just guessing. I don't think it's really a matter of which is a better set up...it's more of a personal preference & I like low pro gas blocks to sit under a lengthened rail. I don't think the longer sight radius that a lengthed rail set up with front buis, carbine to mid-length in my particlar case, is that benefitial, however, some folks prefer it. |

one thing that I have noticed, is that you can move quite a few of the free float rails out there, up, down, side to side. not much, but it is noticeable
put a bipod under the front of your rail and prone out, and you may have a different point of aim (rail mounted BUIS ) than if you would shooting off hand. I like the gas block mounted sight, because it is affixed to the barrel. the barrel wont flex with a free float rail and a bipod. just my observations though, YMMV |
