Arken Optics SH4 GEN2 4-16X50 Rifle Scope FFP
The Arken SH4 GEN2 is one of the most impressive budget-friendly precision scopes I’ve mounted on my Colt Expanse M4. Built with a 30mm tube and FFP reticle, it’s designed for shooters who want consistent holdovers at any magnification.
Product Specs
Pros
Cons
Glass clarity is surprisingly good with minimal edge distortion. I noticed slight chromatic aberration at 16x but nothing that affects target shooting. The reticle is clean and ideal for holdovers.
Eye relief feels consistent around 3.5 inches, and the eye box is forgiving at mid-range magnification. At max zoom, head positioning becomes more critical.
Durability is excellent. I mounted it using a 30mm cantilever mount and ran about 400 rounds of 62gr ammo—the zero held perfectly.
Turrets are tactile with crisp clicks. I performed a box test and tracking was accurate.
Magnification is ideal for 100–400 yard shooting. Parallax adjustment works smoothly.
Mounting was straightforward, and it includes basic accessories.

How to Choose the Right Scope for This Pistol
Choosing the right optic for a Colt Expanse M4 requires balancing weight, magnification, and shooting style. Since this rifle is lightweight and chambered in 5.56 NATO, it excels in target shooting from 50 to 500 yards.
First, consider magnification. For target shooting, I find 3-9x or 4-16x ideal. Lower magnification works for close targets, while higher zoom helps with precision at distance.
Next is focal plane. FFP scopes allow accurate holdovers at all magnifications, which is beneficial for dynamic shooting. SFP scopes are simpler and often cheaper.
Eye relief is critical. AR platforms require at least 3.5 inches to avoid discomfort and ensure proper positioning.
Durability matters as well. Even though recoil is mild, consistent firing can shift cheaper optics.
Finally, consider mounting. A cantilever mount is usually best for AR rifles, ensuring proper eye alignment.
