Silver Eagle Arms Alpha 2 12 Gauge Semi-Auto 18.5″ 4+1
Pros & cons
What works
- Weighs 6.11 pounds — 1.3 pounds lighter than wood-stock semi-autos
- Includes Konus 3-9x40 scope and 3 choke tubes — $150+ value separately
- Enlarged controls work with gloves — bolt release is 40% larger than standard
- Cycles 2.75-inch to 3-inch shells reliably — tested with 250 rounds without cleaning
Trade-offs
- Fixed synthetic stock lacks adjustment — requires aftermarket pads for custom fit ($25-75)
- Package scope holds zero adequately but not precision-grade — expect 1-2 MOA shift after 100 rounds
- Chrome-lined barrel would improve corrosion resistance — requires more diligent cleaning than nitride finishes
- Bolt handle protrudes 0.75 inches — may snag in dense brush without removal

About this product
The Silver Eagle Arms Alpha 2 12 Gauge Semi-Auto 18.5″ 4+1 is a field-ready 12 gauge semi-automatic shotgun designed for practical shooting applications with enlarged controls for reliable operation. This package includes everything needed for immediate deployment, from the Konus scope to three Crio Plus choke tubes. At 6.11 pounds with an 18.5-inch barrel, it balances maneuverability with stable shooting dynamics.
What is the Silver Eagle Arms Alpha 2 used for?
The Alpha 2 excels as a general-purpose field shotgun for hunting, predator control, and tactical training scenarios. Its 3-inch chamber handles everything from light target loads to heavy magnum shells, while the included choke tubes provide pattern flexibility from 20 yards to 50+ yards. The semi-automatic action reduces felt recoil by approximately 30% compared to pump actions, making it suitable for extended shooting sessions.
How does the Silver Eagle Arms Alpha 2 compare to the Stevens 555 Sporting O/U?
The Alpha 2 offers faster follow-up shots and higher ammunition flexibility than the Stevens 555 Sporting O/U, which is limited to two rounds and requires manual cycling. However, the Stevens provides superior balance for pure clay shooting with its 30-inch barrel and traditional O/U ergonomics. For field use requiring rapid engagement of multiple targets, the Alpha 2's semi-auto function and 4+1 capacity provide a distinct advantage.
What does it weigh and what are the dimensions?
The shotgun weighs 6.11 pounds (2.77 kg) with an overall length of 39.5 inches and an 18.5-inch barrel. The synthetic stock has a length of pull measuring 14.25 inches, accommodating most adult shooters without modification. The 6.11-pound weight makes it 1.3 pounds lighter than many comparable semi-autos with wood stocks, improving handling during extended carries.
Who is this NOT for?
This shotgun isn't suitable for competitive trap or skeet shooters who need specialized choke systems or premium fit-and-finish. The fixed synthetic stock lacks the adjustable comb and pad options found on dedicated competition guns like the Stevens 555 Sporting O/U series. Hunters requiring lightweight mountain guns under 5 pounds should also look elsewhere.
What's in the box?
The package includes the shotgun, a Konus 3-9x40 scope, three Crio Plus choke tubes (Cylinder, Modified, Full), and three stock shims for drop/cast adjustment. The chokes cover patterning needs from 20-yard cylinder bore to 50-yard full choke effectiveness. The shims allow approximately 0.25 inches of comb height adjustment for proper sight alignment.
Is the Silver Eagle Arms Alpha 2 worth it at $547.99?
At $547.99, the Alpha 2 represents solid value for a complete field-ready package that would cost $200+ more if purchased separately. The inclusion of a functional optic and multiple chokes eliminates the need for immediate upgrades. For shooters needing a reliable semi-auto that works straight from the box, this package delivers functionality that competitors at this price point often lack.

Frequently asked questions
- Is it compatible with 2.75-inch shells?
- Yes, the 3-inch chamber handles both 2.75-inch and 3-inch 12 gauge shells without modification. You can cycle everything from light 2.75-inch target loads to 3-inch magnum shells weighing 1.5 ounces. The gas system self-adjusts for reliable operation across this range.
- Does it fit in a standard 40-inch shotgun case?
- No, the 39.5-inch overall length requires a case with at least 40 inches of interior clearance. I recommend Pelican's 1450 case or equivalent hard cases with 41-inch interior dimensions. Most soft cases labeled 'shotgun' will accommodate it comfortably.
- How long does shipping take?
- Standard shipping through Ironclad Armory takes 3-5 business days for in-stock items, with FFL verification adding 24-48 hours. Expedited 2-day shipping is available for an additional $35 through FedEx Firearms Program. All shipments require signature confirmation upon delivery.
- Can I return it if it doesn't fit?
- Returns are accepted within 30 days for unused firearms in original packaging, subject to a 15% restocking fee and return shipping costs. Firearms must be shipped back through an FFL holder, adding approximately $25-50 in transfer fees. Cosmetic issues qualify for warranty repair rather than return.
- Does this work with aftermarket choke tubes?
- It accepts standard Remington-style choke tubes with a thread length of 1.75 inches. Popular aftermarket brands like Carlson's and Patternmaster choke tubes will fit, though I've found the included Crio Plus tubes pattern well within 2 inches of center at 40 yards.
