Detailed Reviews
1. Vortex Optics Strike Eagle 1-6x24 FFP Riflescope
The Strike Eagle 1-6x24 is one of my favorite LPVOs for the S&W FPC because it’s fast, tough, and matches the carbine’s balance perfectly. It offers both CQB speed and extended-range precision in one lightweight package.
Product Specs:
Pros:
True 1x for rapid target acquisition FFP reticle scales with magnification Crisp, daylight-bright illumination Durable aircraft-grade aluminum body Cons:
Slight edge distortion at 6x Eye box tightens at full zoom Glass Clarity & Reticle:
The EBR-8 reticle provides an intuitive BDC ladder ideal for 9mm drop compensation out to 200 yards. Edge-to-edge clarity is solid, though not razor-sharp like the Razor HD series.
Eye Relief & Eye Box:
At 3.5 inches, the eye relief feels generous. The eye box is forgiving up to 4x, but requires a steady cheek weld at 6x.
Durability:
Built to military-grade standards, it shrugged off several hundred rounds on my FPC without a hint of zero shift.
Elevation & Windage Knobs:
The turrets click crisply at 1/4 MOA per click. No zero stop, but zero retention is flawless.
My Experience:
Mounted with Vortex 30mm low rings, I achieved a dead-on zero in just 5 rounds at 50 yards. It held zero perfectly after 400 rounds of testing.
Online Feedback:
On Reddit’s r/guns, several users noted it’s one of the best mid-range LPVOs for PCCs thanks to its fast reticle and reliable illumination.
Verdict:
The Strike Eagle 1-6x is nearly tailor-made for the S&W FPC—tough, flexible, and perfectly sized.

Large 34mm tube for better light transmission True 1x and usable 8x magnification Tactile, positive turrets Excellent illumination control Cons:
Slightly heavier than competitors Turrets are exposed, not capped Glass Clarity & Reticle:
The VPR reticle is etched and crisp, giving precise hold points for both close and mid-range. Color fidelity is impressive under daylight.
Eye Relief:
3.3–3.8 inches—comfortable for both standing and prone shooting.
Durability:
Arken’s anodized aluminum housing handled multiple range sessions and wet conditions without any fogging or drift.
My Experience:
Mounted on my FPC with a 34mm Arken one-piece cantilever, it zeroed at 50 yards in 6 rounds. Held zero over 500 rounds with consistent sub-2” groups at 100 yards.
Community Feedback:
Forum users praise its value. Many consider it a “budget Razor Gen III” because of its reticle precision and clarity.
Verdict:
If you want an FFP optic that can handle the FPC’s recoil and offer both speed and reach, the EP8 is phenomenal value.
3. Primary Arms SLX 1-6x24mm SFP Illuminated ACSS Gen III
Primary Arms’ SLX series has become legendary in the LPVO world, and the ACSS Gen III model is ideal for shooters who prefer intuitive holdovers with minimal adjustment.
Specs:
Reticle: ACSS Gen III (SFP, illuminated) Pros:
ACSS reticle = fast target engagement Bright illumination for daylight use Affordable yet battle-tested Cons:
Slightly less field of view than EP8 Glass Clarity & Reticle:
The ACSS reticle is unmatched for 9mm carbines—holdovers, ranging brackets, and moving target leads are built in.

The SIG Tango-MSR is a beast of versatility, blending red-dot speed at 1x with true mid-range magnification at 10x.
Specs:
Pros:
10x zoom range covers CQB to 300 yards Comes with a quality mount Excellent illumination system Cons:
Slight fisheye effect on 1x Illumination dial is stiff Glass Clarity & Reticle:
The BDC6 reticle offers clear bullet drop holds for 9mm up to 200 yards. Glass is vivid, and edge clarity remains stable up to 8x.

Verdict:
A traditional precision option for FPC owners who want clean magnification and unmatched value.
