Yes I mounted a pop-up Front Site I got from Bushmaster and the rear pop-up is a low profile arms site.. They are simply "back up" sites and are very accurate ..My plan was to leave them on in case they are ever needed, thats why the QR Rings for the scope.
The risers came with the rifle, I would prefer to not use the risers at all. Someone showed me this LaRue set up and the picture has a 2.5x10x56 Trijicon scope setting on a Flat top rail with pop-up rear sites...Its similar but its a different rifle and rear sight flavor..SO, we shall see? I will order the LaRue mount today and hopefully after its all done with or without the rear site it will be what I want. Right now I am not that happy with the mounting system, although I can get to the charging handle easily. The more I look at this rear site, I think Im going to remove it and leave the front one on. The rear site can be mounted fairly quickly. I can stash it in the but plate storage compartment.... My intent was to make this AR as versatile as possible as far as Varmint Rifles go...
Barrel is 1-8 twist and I will be reloading 77gr HPBT MG, RL-15, using Lapua Brass. Im also going to try the 70gr TSX BT's Bullets using the same stuff.
