I'm building my first AR-15 (JP, 18") and could use some recommendations for optics. I'll be shooting mostly bench and prone 25, 100, and 300yds. Budget is max $1200 (unless you make a strong case).
From what I've found I'm likely looking at a 1-6 or 1-8 LPVO, or something like a 2-10 with a possible offset RD. I'd really appreciate any thoughts on what makes the most sense for this!
For 300 and in, I'd be looking at a second focal plane 1-6. For your stated budget, including a good mount, I'd go with a Trijicon Credo 1-6, second focal plane. Not the HX. The one with the etched reticle with BDC for 5.56. Put it into a Leupold Mark AR mount. This is a very nice rig.
My primary LPVO is an NX8, but I take that rig out beyond 600 pretty often. Cut that distance in half and the NX8 is wholly unnecessary.
Honestly, if this is going to be a bench and prone gun, you can get a lot more for your money by going with a 2-10 or 2-12x. My 16" 800 yard rig has a Leupold Mark 4HD on top of it. You can get the non illuminated model for about $1k. In terms of actually sending rounds down range, the Mark 4 runs rings around the NX8. Don't get a scope with a 1x, unless you need that 1x and the form factor typical of an LPVO.
Of course, you could always go with a Vortex venom 1-6x AND an Athlon Helos 2-12 and have both and still be within your budget.
