I'm about to buy my second pa 1 - 8 - Primary Arms SLx 1-8x24mm Rifle Scope, 30mm Tube, Second Focal Plane (SFP)

I have compared a few variable Scopes side by side and I think the primary arms 1 to 8 is the best value and also ranks pretty high overall even against the best scopes.

The thing that makes it stand out is the acss reticle. It is ideal for CQB situations where your battery is dead and you have to just use the etched reticle. The Horseshoe is small enough and thick enough that you can see it without illumination. Some of the other horseshoes that I tried out were too big and too thin to be able to use reliably for aiming with just the etched reticle in CQB and low light conditions.

At distance or with the illumination, they all come in about the same.

I do not like first focal plane because the Horseshoe shrinks to the size of a tiny Dot and you can not use it for fast aiming. The second focal plane of this scope is better for most uses.
