Detailed Reviews
Arken Optics EP5 5-25X56 Rifle Scope FFP
The EP5 is a serious precision optic at a surprisingly accessible price point. Mounted on my BRN-10A using a 20 MOA one-piece mount, it transformed the rifle into a long-range performer.
Product Specs
Pros
Cons
Glass clarity is impressive, especially in bright daylight. I noticed minimal chromatic aberration even at 25x, and edge clarity remained consistent. The reticle is detailed but not overwhelming, making it ideal for precise holdovers.
Eye relief is forgiving for a .308 platform. On my BRN-10A shooting 168gr match ammo, I never experienced scope bite. The eye box tightens at max zoom, but that’s expected.
Durability is outstanding. After 400+ rounds, the scope held zero perfectly. The turrets are tactile, and my box test confirmed accurate tracking.
Magnification range is perfect for 100–800 yards. Parallax adjustment is smooth and precise.
Mounting requires 34mm rings, and I recommend a sturdy mount due to weight.
From personal experience, this scope excels on the bench. It’s heavy, but precision is top-tier.
Online discussions often praise its value, especially compared to scopes twice the price.
Verdict: Ideal for long-range shooters on a budget.

How to Choose the Right Scope for This Pistol
Choosing the Best Scope For Brownells Brn-10a depends heavily on your shooting style and distance goals. The BRN-10A, chambered in .308, is naturally suited for mid-to-long-range target shooting, so your optic needs to complement that capability.
First, consider magnification. If you primarily shoot at 100–300 yards, a 3-9x or 4-12x scope is sufficient. However, for 500–800 yard shooting, you’ll benefit from 6-24x or higher magnification. I personally prefer variable scopes that allow flexibility across distances.
Second, think about focal plane. First Focal Plane (FFP) scopes are better for target shooters who rely on holdovers because the reticle scales with magnification. Second Focal Plane (SFP) scopes are simpler and often cheaper, but less versatile for dynamic shooting.
Third, durability matters. The BRN-10A produces noticeable recoil, especially with 168gr or 175gr match ammo. Your scope must handle repeated recoil without losing zero.
Finally, consider mounting. A solid one-piece mount with proper eye relief is essential for comfort and accuracy.
FAQs

3. Will budget scopes hold zero on .308?

Only for mobility—on a bench, weight can improve stability.
Conclusion
Choosing the right optic doesn’t have to be expensive. With the right balance of clarity, durability, and tracking, you can turn your BRN-10A into a precision tool. The scopes above prove that budget-friendly options can still deliver serious performance. If your goal is consistent target shooting, any of these choices will serve you well.
