Not an acog... but for the price you can't beat this optic. - Primary Arms 5x36mm Illuminated Prism Rifle Scope

Recently I went about building my first AR-15 from the ground up and wanted an optic that was inexpensive and FDE - surprisingly there aren't many out there for under $1,500. Then I saw the Primary Arms fixed 5x36 in FDE which for the price has turned out to be an excellent optic not to mention if came in FDE which my new rifle I Cerakoted in H-Series: Magpul FDE, Magpul Foliage Green, and Patriot Brown using the Kryptek pattern. The gun turned out nice and the FDE optic made it complete.

From a technical standpoint this is the first Primary Arms I've purchased and would definitely look at other models if I were in the market. Like the other reviewers I found it to be heavy but very well made. The glass was very clear; not ACOG clear, but clear. The BCD reticle is definitely small but after firing 30 rounds I became used to the size. Full disclosure I have an ACOG 4x32 in FDE on my SCAR 16L and like I said it's not an ACOG but I really wasn't expecting that. For those in the market for a fixed power optic this a great choice. The option to choose between Red and Green is also a plus, and it's not a gimmick. One key bonus that I noticed was as it became dusk the green was more visible then the red, and as the sun really started to set the glass in this optic really soaked up what little light was left and it really shined even with the lowest green setting. I was very impressed at this point and could easily make out the targets at 100M even hitting a couple soda cans in what many would consider nearly dark.

Bottom-Line: If you can get past the small size of the BDC reticle you'll really enjoy this Optic.
