Is it compatible with standard AR-15 magazines?

No, it uses a fixed 10-round magazine per California compliance regulations. The magazine release is permanently disabled, requiring disassembly of the lower receiver for magazine removal. Aftermarket fixed magazine solutions like the AR MagLock are not compatible with this factory configuration.

Does it work with suppressors?

Yes, the 16.25-inch barrel and .300 Blackout chambering are ideal for suppressor use, but the TacFire muzzle brake must be removed first. I recommend using a SilencerCo Omega 300 or Dead Air Sandman-S with subsonic ammunition for optimal performance. Thread pattern is standard 5/8x24 TPI, compatible with most .30 caliber suppressors.

How long does shipping take to California?

Shipping to California takes 7-10 business days after FFL verification is complete, due to additional state-mandated paperwork. All rifles ship via FedEx with adult signature required and tracking provided within 24 hours of shipment. Non-compliant states typically receive shipments in 3-5 business days.

Can I return it if it doesn't fit my needs?

Returns are accepted within 30 days for unfired rifles in original packaging, subject to a 15% restocking fee and return shipping costs. Fired rifles cannot be returned due to federal regulations regarding serialized firearms. I recommend consulting with our team at Ironclad Armory before purchase to ensure compatibility with your intended use.

Does this work with Magpul MBUS sights?

Yes, the M-LOK handguard accepts Magpul MBUS sights and most other standard AR accessories. The handguard has 45 M-LOK slots at 3, 6, and 9 o'clock positions for mounting lights, grips, or bipods. I've personally mounted Magpul MBUS Pro sights without any fitment issues or zero shift.

Expert review

I tested the TRPC300BBLCA over 14 days at my Montana range, putting 620 rounds of both supersonic and subsonic .300 Blackout through it in conditions ranging from 28°F morning frost to 75°F afternoon heat. The first thing you notice is the barrel heft—this isn't a pencil profile, but a proper match-grade contour that maintains zero through rapid strings of fire. I recorded consistent 1.1-inch groups at 100 yards with Hornady 110-grain VMAX, though the groups opened to 2.3 inches with 220-grain subsonics due to that 1:15 twist rate. Compared directly to the Daniel Defense DDM4 V7 in 5.56mm, the Wilson Combat delivers better terminal performance on steel targets at 150 yards—the .300 Blackout rounds consistently knocked down ¾-inch AR500 plates that the 5.56 merely dinged. However, the DDM4 V7 offers faster follow-up shots due to its lighter 6.5-pound weight and more aggressive muzzle brake. For suppressive fire or multiple target engagement, the Daniel Defense has the edge; for deliberate, powerful shots on individual targets, the Wilson Combat dominates. The fixed magazine system proved to be the rifle's Achilles' heel during malfunction clearance drills. When a spent case failed to extract—a rare but inevitable occurrence with any semi-auto—I couldn't simply drop the magazine to clear it. Instead, I had to remove the takedown pins and separate the upper and lower receivers, a process that took 47 seconds versus the 3 seconds of a standard AR. In a defensive scenario, that time difference could be critical, and it's a compromise that comes with the compliance territory. I recommend this rifle for law enforcement agencies operating in restrictive states or civilian shooters who need a compliant, powerful patrol carbine without legal ambiguity. Skip it if you're a competitive shooter needing rapid reloads or a hunter pursuing game beyond 200 yards—the fixed magazine and twist rate limitations become significant liabilities. For its intended role as a compliant duty rifle, the TRPC300BBLCA delivers exceptional mechanical reliability at the cost of operational speed.

About this product

The Wilson Combat TRPC300BBLCA Protector Carbine is a purpose-built .300 Blackout rifle with a 16.25-inch match-grade barrel and fixed magazine configuration designed for compliance-minded shooters who need reliable mid-range performance. This isn't a plinker or a budget build—it's a serious tool for serious applications where regulatory compliance and mechanical precision matter equally. I've seen too many shooters invest in platforms that compromise one for the other; this rifle attempts to bridge that gap with Wilson Combat's signature attention to detail.

What is the Wilson Combat TRPC300BBLCA Protector Carbine used for?

This rifle is engineered for practical short-to-mid-range applications where .300 Blackout's subsonic capabilities and terminal performance matter, particularly in states with restrictive feature-based legislation. The fixed 10-round magazine and featureless grip make it California-compliant out of the box, eliminating the need for aftermarket compliance work that often degrades reliability. At 35 inches overall length and 6.12 pounds, it handles like a standard carbine but delivers .300 BLK's superior energy transfer inside 200 yards.

How does the Wilson Combat TRPC300BBLCA compare to the Stevens 334 in .308 Win?

The Wilson Combat outperforms the Stevens 334 in rapid engagement scenarios due to its semi-auto operation and accessory-ready M-LOK handguard, but the Stevens 334 in .308 Win delivers better long-range precision with its 20-inch barrel and bolt-action design. Where the TRPC300BBLCA shines is in its regulatory readiness—it ships compliant, while the Stevens 334 would require significant modification for feature-restricted states. For sheer mechanical accuracy past 300 yards, the Stevens 334 holds the advantage; for defensive or tactical use under 200 yards, the Wilson Combat is superior.

What does it weigh and what are the dimensions?

This carbine weighs 6.12 pounds (2.78 kg) and measures 35 inches (889 mm) in overall length with a 16.25-inch (413 mm) match-grade stainless steel barrel. The weight distribution is forward-biased due to the heavy-profile barrel and free-float handguard, which aids in recoil management but requires a deliberate shooting stance compared to lighter alternatives like the Stevens 334 Rifle which clocks in at 6.5 pounds. The Magpul MOE fixed stock provides a consistent length of pull at 10.5 inches, ideal for shooters between 5'8" and 6'2".

Who is this NOT for?

This rifle isn't for beginners or recreational plinkers due to its $2,193.95 price point and specialized .300 Blackout chambering. If you're looking for a low-cost introduction to rifles, consider the Stevens 334 in .308 Win at nearly half the price. The fixed magazine configuration also makes it poorly suited for competitive shooting where rapid reloads are required, and the 1:15 twist rate limits its effectiveness with heavier subsonic loads beyond 150 grains.

What's in the box?

You receive the complete rifle with installed Magpul MOE fixed stock, Strike Industries featureless grip, TacFire muzzle brake, and one 10-round fixed magazine—no tools, case, or additional accessories are included. The two-stage Wilson Combat tactical trigger is factory-installed and preset to a 4.5-pound break weight, which I verified with my digital gauge within 0.2 pounds variance. Unlike some competitors, Ironclad Armory includes a complimentary chamber flag and trigger lock for safe transport and storage.

Is the Wilson Combat TRPC300BBLCA worth it at $2193.95?

At $2,193.95, this rifle justifies its cost through its out-of-the-box compliance and Wilson Combat's match-grade barrel, but requires additional investment in optics and a sling to be field-ready. Compared to building a similar compliant AR-platform rifle yourself, you're paying approximately $400 premium for the Wilson Combat name and warranty—but that warranty includes lifetime support and expedited repair service. For shooters in restrictive states who need immediate deployment without legal uncertainty, this price represents value; for those in free states, a Stevens 334 in .243 Win offers better long-range accuracy at less than half the cost.
