Acog is proof that you get what you pay for. - Trijicon 4x32 ACOG Rifle Scope w/ Colt Knob Thumbscrew Mount

I'm finally doing well enough to afford an ACOG but I can't afford three so I bought a Primary Arms 3×32 prism scope for my .300BO and the 5×36 version for my other 5.56 ar. The PA prism scopes are okay for the money but they just don't compare to a real ACOG. The 4×32 ACOG has the perfect balance of magnification and field of view. The PA 3×32 prism just doesn't quite magnify enough for my old worn out eyeballs and the field of view is like looking through a straw compared to the ACOG. The PA 5×36 prism has a bigger sight picture than the 3×32 but the magnification is only slightly better than the ACOG but it has significantly less field of view. The clarity of the glass in the ACOG is noticeably better than the PA prism scopes as well. I would give the ACOG 5 stars all day if it just had a smidge more eye relief - you really gotta get your eye right up close to get the full sight picture and if you don't have the stock firmly against your shoulder you'll end up hitting your eyebrow. That and the high price of this scope knock it down to 4.75 stars for me. I still think its worth the price if you can afford it.
