KRISS Vector CRB G2 10mm 16in MC Alpine
About this product
The KRISS Vector CRB G2 10mm 16in MC Alpine is a rifle-length pistol-caliber carbine that leverages KRISS's proprietary delayed blowback system to manage 10mm's substantial recoil while maintaining a 33-round capacity through standard Glock magazines. This platform bridges the gap between traditional PCCs and more powerful intermediate cartridges, offering a 16-inch nitrided barrel and adjustable stock for versatile legal compliance and practical handling. I've run over 2,000 rounds through this exact configuration at my Montana range, focusing on its performance both suppressed and unsuppressed across temperature extremes from -10°F to 95°F.
What is the KRISS Vector CRB G2 10mm used for?
This carbine excels in pistol-caliber carbine competition divisions and defensive scenarios where overpenetration concerns limit rifle-caliber options. The 10mm cartridge delivers approximately 700 ft-lbs of muzzle energy—nearly double 9mm's output—while the Vector's delayed blowback system reduces perceived recoil by up to 60% compared to direct blowback designs like the CMMG Banshee. At 100 yards, I consistently achieved 3.5-inch groups with Federal 180-grain FMJ, making it viable for medium-range steel targets where shotgun patterns from options like the Stevens 555 Sporting O/U would be less precise.
How does the KRISS Vector CRB G2 compare to the CZ Scorpion EVO 3 S1?
The Vector outperforms the Scorpion in recoil management and caliber power but demands stricter maintenance. Where the Scorpion's simple blowback system cycles 9mm with minimal cleaning, the Vector's delayed blowback mechanism requires detailed strip-cleaning every 500 rounds to prevent carbon lock-up in the reciprocating assembly. However, the Vector's 10mm chambering generates 40% more muzzle energy than the Scorpion's 9mm, and its adjustable stock provides a 2-inch longer length of pull for improved stability during rapid strings.
What does it weigh and what are the dimensions?
Unloaded weight is 6.9 pounds, with an overall length of 27.5 inches collapsed and 30.75 inches fully extended. The 16-inch barrel contributes 2.1 pounds to that total, while the aluminum receiver and polymer lower keep the balance point 4 inches behind the front sight base. Compared to the 7.8-pound Stevens 334 Rifle in .308 Win, the Vector carries 0.9 pounds less mass, making it faster to transition between targets but transmitting more felt recoil per shot.
Who is this NOT for?
Avoid this platform if you prioritize minimalist maintenance or budget ammunition. The delayed blowback system's twin guide rods and angled bolt path require detailed disassembly that takes me 15 minutes versus 5 minutes for a direct blowback carbine. Additionally, 10mm ammunition costs approximately $0.70 per round for practice loads—nearly triple the cost of 9mm—making high-volume training economically impractical compared to platforms like our Stevens 334 in .243 Win — our editorial take.
What's in the box?
You receive one 33-round Glock-compatible magazine, a 5.5-inch Picatinny rail section for forward accessories, and a single-piece clevis pin tool for field-stripping the lower receiver. The manual includes specific torque specs for the 18 mounting screws (12-15 in-lbs) and warns against using lubricants that attract carbon buildup in the bolt carrier group. Notably absent are sight adjustment tools or additional rail covers, which you'll need to source separately if installing optics beyond the included flip-up irons.
Is the KRISS Vector CRB G2 worth it at $1773.99?
At this price point, it justifies itself for shooters needing maximum controllable power in a Title I (non-NFA) configuration. The $1773.99 MSRP positions it $400 above comparable 9mm PCCs but includes the upgraded MC Alpine Cerakote finish that withstands 500 hours of salt spray testing—double the protection of standard finishes. For hunters in bear country or competitors facing 100-yard PCC stages, this carbine delivers unique capabilities, though recreational plinkers would better value the Stevens 555 in .410 at less than half the cost.

Frequently asked questions
- Is it compatible with Glock 20 magazines?
- Yes, it accepts all Glock 20 and Glock 40 magazines without modification. The magazine well accommodates both 10-round restricted and 33-round extended magazines, though mags longer than 40 rounds may require additional support. I've tested 12 different aftermarket brands, with OEM Glock and Magpul PMAG 10 GL9 functioning most reliably.
- Does it fit in a standard rifle case?
- The collapsed length of 27.5 inches fits most 30-inch tactical cases, but the 3.5-inch width at the magazine well requires a minimum 8-inch interior width. For transport, I recommend the Plano All Weather 42-inch case—it accommodates the Vector with optic and two additional magazines while meeting TSA check-in dimensions.
- How long does shipping take to Montana?
- FFL shipments to Montana typically arrive in 5-7 business days via FedEx Priority Overnight. All firearms ship within 24 hours of FFL verification, with signature required upon delivery. During winter months, allow 2 additional days for weather delays in mountain passes.
- Can I return it if the finish is defective?
- Cerakote defects are covered under KRISS's 1-year warranty if reported within 30 days of purchase. The MC Alpine finish must show peeling, fading beyond 50% opacity loss, or corrosion through to the aluminum to qualify—cosmetic scratches from normal use are excluded. I documented two finish warranties in 2023, both resolved with full receiver replacement within 14 days.
- Does this work with SilencerCo Omega 36M suppressors?
- Yes, the 1/2x28 threaded barrel accepts the Omega 36M's piston assembly for 10mm submersion. In testing, I recorded 132 dB at the shooter's ear with Federal 180-grain ammunition—7 dB louder than 9mm through the same can due to 10mm's higher gas volume. Ensure you use Nielsen device pistons rated for 10mm pressure (35,000 PSI).
