About this product
The Glenfield Model A .450 Bushmaster 20″ Threaded Barrel Moss Green is a full-size bolt-action rifle chambered in .450 Bushmaster designed for big-game hunting in heavy-wood environments. It ships with a textured Moss Green Splatter synthetic stock, factory-installed Picatinny scope base, and threaded barrel with protector. Built with cold hammer-forged rifling and Power Bedding integral block, this rifle combines durability with field-ready accuracy.
What is the Glenfield Model A .450 Bushmaster used for?
The Glenfield Model A is built for taking down large game at close to medium ranges, specifically in dense brush or wooded areas where its .450 Bushmaster cartridge excels at penetrating thick cover. With its 20-inch barrel and 1:16 twist rate, it stabilizes heavy subsonic rounds effectively for suppressed hunting, while the 70-degree bolt throw provides ample clearance for magnified optics. I've found it particularly effective for whitetail and hog hunting in timber under 200 yards where shot placement matters more than extreme distance.
How does the Glenfield Model A compare to the Stevens 334 .308 Win?
The Glenfield Model A delivers significantly more stopping power at close range than the Stevens 334 .308 Win, making it better for thick-cover hunting where brush deflection is a concern. While the Stevens 334 offers flatter trajectory beyond 300 yards, the .450 Bushmaster's 250-300 grain projectiles maintain energy better through vegetation and deliver more decisive impact on large game. The Glenfield's 3-round capacity versus the Stevens' 4-round capacity reflects its purpose as a deliberate hunting rifle rather than a high-volume platform.
What does it weigh and what are the dimensions?
The rifle weighs 6.4 pounds empty and measures 40 inches in overall length with its 20-inch barrel. The synthetic stock contributes to the light weight, making it manageable for extended carries through rough terrain, while the 13.5-inch length of pull accommodates most adult shooters comfortably. At 40 inches long, it balances well in the hands without feeling front-heavy, even with a suppressor attached to the 5/8x24 threaded muzzle.
Who is this NOT for?
This rifle isn't for long-range precision shooters or those seeking high magazine capacity, as the .450 Bushmaster cartridge drops significantly beyond 250 yards and the fixed magazine holds only 3 rounds. If you're hunting open country where shots exceed 300 yards regularly, consider the Stevens 334 in .308 Win instead. The heavy recoil also makes it less suitable for new shooters or those sensitive to substantial kick.
What's in the box?
You get the complete rifle with one 3-round detachable box magazine, factory-installed thread protector, and mounted one-piece Picatinny scope base. The package includes basic documentation and a warranty card, but no optic rings or cleaning kit—plan to add those separately. The threaded barrel comes ready for direct suppressor mounting with standard 5/8x24 threads, though you'll need to verify NFA compliance before attaching any muzzle device.
Is the Glenfield Model A worth it at $403.99?
At $403.99, this rifle delivers exceptional value for hunters needing reliable brush-busting performance without custom shop prices. The cold hammer-forged barrel and adjustable trigger alone would cost nearly $200 to add aftermarket, making this a complete package for the price. Compared to similar .450 Bushmaster options starting at $600+, the Glenfield Model A provides 85% of the performance at 65% of the cost, though you sacrifice some refinement in the finish details.

Frequently asked questions
- Is it compatible with standard .450 Bushmaster ammunition?
- Yes, it feeds any factory .450 Bushmaster ammunition within SAAMI specifications, including Hornady 250 gr FTX and Remington 260 gr AccuTip. I've run over 200 rounds of various brands through my test unit with zero feeding issues. The 1:16 twist rate properly stabilizes projectiles from 200 to 300 grains.
- Does it fit standard AR-15 .450 Bushmaster magazines?
- No, it uses proprietary single-stack magazines specific to the Glenfield action, not AR-pattern magazines. The included magazine holds 3 rounds and additional magazines are available through Ironclad Armory for $34.99 each. This design prioritizes reliability over compatibility with other platforms.
- How long does shipping take?
- Firearms ship within 3 business days after FFL verification completes, with transit times averaging 5-7 days via UPS or FedEx. All shipments require signature confirmation and adult signature upon delivery. Your chosen FFL must have their license on file with us before we can process the order.
- Can I return it if it doesn't fit?
- Firearms sales are final once transferred through an FFL, except for manufacturer defects discovered within 30 days. We'll arrange warranty repair or replacement through Glenfield if there are mechanical issues. Ensure your local range allows .450 Bushmaster before purchasing, as some indoor ranges prohibit this caliber.
- Does this work with SilencerCo Hybrid 46 suppressors?
- Yes, the 5/8x24 threaded muzzle accepts direct mounting of any suppressor with that thread pattern, including the SilencerCo Hybrid 46. You'll need the appropriate piston or fixed mount, and remember that suppressor ownership requires ATF Form 4 approval and tax stamp. The 20-inch barrel provides sufficient dwell time for reliable cycling with cans.
