Anyone have experience with the Knights Flip up front site for a rail hand guard. Pros - cons?? I plan on mounting a low power scope to a 16" A3 Bushmaster with a milled front site base. Also--any feelings about Bushmasters B.M.A.S. rail hand guards, The Knights  version, and the C - more Version.  The C - more is under 16 oz. Strength and the least weight is what I am interested in. Free float or standard. Barrel cooling as well. Which one of them would you guys consider and why.  thanks --- John.

Precision Reflex has a flip up fron site that is supposed to be pretty good.  I havn't seen one up close, but in the pictures it looks down right scnazzy.
This pic ain't great but it was all I could find on short notice.  It comes from A.R.M.S. website

I have the Knights' front flip up sight (PN 99051) on a long railed handguard, and it works great.  It  has a very low profile when folded and seems pretty sturdy when deployed.  It gives you pretty much the same sight picture as A2 tower.  It's probably not as accurate on a FF tube as a barrel-mounted sight because you can pull the FF tube off axis from the barrel if you are using a sling.

This is a close up of one of the PRI sights, this ones uses two screws and require the barrel notches be cut. Some other versions use offset screws and I think require no modification of barrel. However the notches are quit easy to do with a file. It's a very nice sight.

Top pic is normal taper pin notches, bottom are notches cut for my version of the PRI sight:

If your looking for insight on forends, check out the 'uppers...' forum, there is a tack with serious comparison between many top notch systems. The top selection around here has been KAC, ARMS & OLY FIRSH, the C-more is not popular and the new one on the block is POF
