I would either go with the EOTech EXPS 3-0 or the Elcan SpecterDr 1-4x.
I went with the EoTech EXPS3-0 in FDE with a G33 magnifier also in FDE, I ordered it last weeks so I expect to receive them this week sometime. They might actually already be here as I got a text from home today saying I have a package notification from Canadapost for a package that they tried to deliver today but I wasnt home.
I haven't received the rifle yet as Wolverine is still waiting on the CFO transfer to go through, but along with the rifle I also ordered a Geissele SSA-E trigger kit
And last night I put in some orders for some other parts, I went with the following parts
LMT spomod stock in black ( I wanted FDE but I seen some pics and their FDE isnt what Im looking for, so I just went with the black)
Tango down quick release forgrip in FDE
Ranier Arms charging handle
knights Armament trigger guard
Troy BUIS in FDE (M4 front/circle rear) May replace with KAC if I can ever find them in stock anywhere
Noveske KX3 (on back order but ordered anyways to see if I can get one)
Thats it for now, next I plan to buy bulk ammo and LAR mags for it. So next question where can I buy good quality LAR pistol mags for this thing? And what ammo do you guys recommend? Seems I can get American Eagle, PMC, or Norinco readily available
