Is it compatible with .300 BLK subsonic ammo?

Yes, it handles both supersonic and subsonic .300 AAC Blackout rounds reliably. The 16.5-inch barrel provides optimal stabilization for heavier subsonic projectiles—I’ve tested with 220-grain S&B subsonics without issues.

Does it fit in a standard backpack?

When folded, it fits in a 20-inch backpack or case—18.5 inches long by 7 inches wide. Compare that to a typical AR-15 at 35 inches collapsed, which requires a full-size rifle bag.

How long does shipping take?

FFL shipments take 3-5 business days once processed. We use UPS or FedEx with adult signature required—plan an extra 24 hours for your FFL to log it in before pickup.

Can I return it if it doesn't cycle properly?

Returns are accepted within 30 days for manufacturing defects, but firearms require an RMA and must ship via FFL. Non-defective returns incur a 15% restocking fee and return shipping costs.

Does this work with SilencerCo Omega 300 suppressors?

Yes, the 5/8×24 threads match the Omega 300’s direct-thread mount. I’ve mounted mine with 18 lb-ft of torque—just remember to check alignment with a rod before firing.

Pros & cons

What works

Weighs 5.2 lb — 1.8 lb lighter than a Stevens 334 .308
Folds to 18.5 inches — 46% shorter than an uncollapsed AR-15
16.5-inch threaded barrel avoids NFA SBR registration
Picatinny rail accepts optics up to 3.5 inches long

Trade-offs

Single-shot only — 3-second reload cycle limits practical rate of fire
No iron sights included — adds $50-$200 for optic or sights
Synthetic stock feels hollow — lacks the heft of walnut or laminate options

Expert review

I tested the Rossi LWC over three weeks at my range outside Bozeman, primarily as a suppressor host and compact training tool. The black oxide finish held up to 200 rounds of mixed subsonic and supersonic ammo without corrosion, and the break-action remained consistently tight with no play—critical for maintaining zero with a mounted Holosun 403R. Compared to the Stevens 334 in .308 Win, the Rossi is 1.8 pounds lighter and 4 inches shorter when folded, but you trade the bolt-action’s 4-round capacity for absolute simplicity. The Stevens is better for hunting or sustained drills; the Rossi excels when every ounce and inch counts for transport or regulatory clarity. The surprise was the stock—while functional, it feels noticeably hollow and flexes under pressure compared to the solidity of a wood-stocked Stevens 555. It doesn’t affect accuracy, but it cheapens the handfeel. I’d budget $150 for a custom stock if you plan heavy use. Buy this if you need a compact, no-hassle suppressor host or a straightforward training rifle where firepower isn’t the goal. Skip it if you expect rapid follow-ups or prefer traditional aesthetics. For the price, it’s a mechanically honest tool that does one thing very well.

About this product

The Rossi LWC .300 AAC Blackout 16.5 in Single-Shot Rifle is a compact break-action carbine designed for shooters who prioritize portability and regulatory simplicity. It features a threaded 16.5-inch barrel, folding synthetic stock, and Picatinny rail—making it ideal for suppressor use and compact transport scenarios where traditional rifles fall short.

What is the Rossi LWC .300 AAC Blackout used for?

This rifle is built for compact-range work, suppressor testing, and small-game hunting where minimal bulk matters. The 16.5-inch barrel keeps overall length manageable when folded, and the 5/8×24 threaded muzzle accepts standard .30-caliber suppressors without NFA paperwork for SBRs—unlike shorter-barreled alternatives.

How does the Rossi LWC compare to the Stevens 334 Rifle?

The Rossi LWC weighs 5.2 pounds unloaded—1.8 pounds lighter than the Stevens 334 in .308 Win—but sacrifices the bolt-action’s 4-round capacity for absolute simplicity. The Stevens 334 is better for sustained firing; the Rossi wins on portability and regulatory clarity for suppressor hosts.

What does it weigh and what are the dimensions?

Unloaded weight is 5.2 pounds, with an overall length of 28 inches unfolded and 18.5 inches folded. The 16.5-inch barrel contributes to a 34-inch maximum sight radius when using optics mounted on the 3.5-inch Picatinny rail.

Who is this NOT for?

This isn’t for high-volume shooters or those needing rapid follow-up shots—the single-shot action requires a 3-second minimum reload cycle. If you need capacity, consider a bolt-action like the Stevens 334 instead.

What's in the box?

You get the rifle, one 5-round cartridge holder (mounted on the stock), and a basic safety manual. No optic, sling, or case is included—plan $40-$60 for a hard case and another $200+ for a micro red dot if you want immediate field readiness.

Is the Rossi LWC worth it at $335.99?

At $335.99, it’s a fair value for a dedicated suppressor host or training tool where simplicity trumps firepower. Compared to converting an AR-pattern rifle to single-shot for compliance, this saves $150 in gunsmithing fees and avoids NFA trust complications.
