Don't buy this thing new - Primary Arms SLx 1-6x24mm Rifle Scope, 30mm Tube, First Focal Plane (FFP)

First off, first focal plane scopes (like this) are generally more expensive and have worse illumination overall than SFP scopes. This is one of the least expensive FFP scopes out there, so you make more than a few compromises. The illumination isn't terribly bright, although the lowest setting is very low, making it useful for low-light visibility of the reticle but bad for using the optic at 1x like a red dot in bright light. This is made worse by the reticle design, which is already hard to pick up fast at 1x due to the horseshoe being the most prominent feature and being quite small at 1x. A few big crosshairs added like a German #1 reticle would fix this if PA ever makes a gen 2 of this optic. Edge-to-edge clarity is good, distortion on 1x isn't great but isn't that big a deal either, and eye relief and exit pupil are both fine. Most importantly, as of time of writing in January 2022, these things are selling for about $300 on the used market, so don't do what I did and pay $400 for one new. I honestly don't know how Primary Arms keeps making optics that are 1) budget-conscious, 2) decent quality, and 3) somehow still overpriced for what you get, but they sure do deliver every time.
