With a few delays I'm about to go into finish mode on my 300 Blackout build. I swapped lowers to an Anderson on sale at PSA and it is NOW in the mail. I have a few question for Primary Arms but I hope to place an order Monday for a new red dot sight. Looking at current availability and pricing the following list is my current (rough) order of preference but I'm looking for input from those with hands-on experience. It is not so complicated - I have a budget for second tier pricing and AM a bargain hunter - bang for the buck but no junk. I have a Vortex SPARC and am totally satisfied with it AND CS and warranty. That said I know a lot of shooters that swear by Primary Arms and I like the company as well. Is their 3MOA that much different than the Vortex 2MOA?? I'm looking for an absolute co-witness setup with Magpul sights. The list: Vortex Sparc Red Dot Sight SPRC 2MOA - $150 PSA, 4 mount options included A+ Primary Arms Red Dot Gen II 3MOA - $70, mount not included - straight 30mm ring is affordable answer for absolute co-witness ($80) Primary Arms Classic Red Dot 3MOA- $70, 30mm straight ring for absolute co-witness ($80) Primary Arms Micro Dot With Removable Base 3MOA - $80, 1/3 co-witness OR $15 for UTG absolute co-witness rail riser ($95) Vortex StrikeFire Red/Green Dot Optic 4MOA - $120 PSA, Included extra-high 30mm = lower 1/3 co-witness - lower ring for absolute for minimal cost ($135) Also ran: Lucid HD7 Bushnell TRS-25 Hi-Rise Thoughts?!?
