Description
The Stag Arms Stag 15 Super Varminter 6.8mm Remington SPC II 20.77″, Black Hard Coat Anodized Fixed Magpul Stock, 10 rd is a purpose-built AR-platform rifle designed for precision medium-range varmint and predator control. It combines the flat-shooting 6.8 SPC II cartridge with a heavy, free-floated barrel and a stable fixed stock system for consistent accuracy. I’ve put a few hundred rounds of Hornady and Federal through this configuration, and it’s a serious tool for a specific job—delivering tight groups on small, fast targets out past 300 yards where a .223 might start to drift. At $1033.99, it represents a solid value for a dedicated varminter that doesn’t require you to build from scratch.
Key Features
- 6.8mm Remington SPC II Chambering: Offers superior terminal performance and less wind drift than .223/5.56 on coyote-sized game and down.
- 20.77″ Heavy Barrel: Free-floated, button-rifled barrel provides increased velocity and consistent point of impact, crucial for those longer shots.
- Fixed Magpul MOE Rifle Stock: Enhances stability for precise shooting from a bench or bipod compared to a collapsible stock.
- Hard Coat Anodized Finish: Durable, corrosion-resistant finish that stands up to field use and varying weather conditions.
- Direct Impingement Gas System: Reliable, mil-spec compatible operation that’s easy to maintain and clean.
Specifications & Details
| Caliber | 6.8mm Remington SPC II |
| Barrel Length | 20.77 inches |
| Stock | Fixed Magpul MOE Rifle Stock |
| Finish | Black Hard Coat Anodized |
| Magazine Capacity | 10 Rounds |

The rifle ships with a 10-round magazine, which is a practical choice for most varminting scenarios where shot placement trumps volume of fire. The upper and lower receivers are forged for strength, and the whole assembly is drop-in ready—you can mount an optic, add a bipod, and head to the range without any fuss. The rifle weighs in around 8.5 lbs unloaded, which is manageable but you’ll definitely want to use a bipod or shooting bags for extended sessions. That weight, combined with the fixed stock, soaks up recoil nicely, making follow-up shots quick. Look, the 6.8 SPC isn’t as ubiquitous as 5.56, but quality ammo from brands like Hornady and Federal is readily available, and its performance on target is the whole point of this platform.
Who This Rifle Is For
This is for the hunter or landowner who needs to reach out and touch prairie dogs, groundhogs, or coyotes with authority and consistency. It’s also a great choice for a shooter wanting a dedicated medium-range AR that isn’t another 5.56. If your primary goal is punching paper at distance with an AR, the 6.8 SPC is a fascinating and effective cartridge to explore. It’s available at firearms-missouri.com for Missouri residents and nationwide.
Pros & Cons
Pros: The cartridge is a significant step up from .223 for varmints and predators. The heavy, free-floated barrel is built for accuracy. The fixed Magpul stock provides a solid, repeatable cheek weld. Stag Arms’ quality control is generally excellent, so you’re getting a reliable out-of-the-box rifle.
Cons: Ammunition cost is higher than .223/5.56. The fixed stock isn’t adjustable for length of pull, which might not suit all shooters. At over 8 lbs, it’s not a rifle you’d want to carry all day for still-hunting—it’s a setup for a stationary or ambush position.
Frequently Asked Questions
Q: Is this compatible with my existing AR-15 lower receiver?
A: Yes, with a caveat. The Stag 15 Super Varminter upper is built on a standard AR-15 platform, so it will mate with any mil-spec AR-15 lower. However, you must use 6.8 SPC-specific magazines in that lower for reliable feeding. Standard 5.56 magazines will not work correctly.
Q: What’s the effective range for varminting with the 6.8 SPC?
A: With the right load and shooter, the 6.8 SPC is capable of ethical, accurate shots on coyote-sized targets out to 400+ yards. Its heavier bullets resist wind better than .223 and carry more energy downrange, making it a more confident choice for those longer pokes across a field.
Q: Can I use this for deer hunting in Missouri?
A: The 6.8 SPC is a legal cartridge for deer hunting in Missouri and is considered an excellent choice by many hunters due to its effective terminal performance. Always check the most current Missouri Department of Conservation regulations for specific caliber and magazine capacity rules for the season you plan to hunt.
