Description
Let me paint you a picture. You’re at the range, and the guy next to you is wrestling with a snappy little 9mm carbine. You pull out your Kriss Vector SBR Gen II 9mm 5.5″ Threaded Barrel Defiance M4 Stock with Adaptor Black 17rd, and the difference is night and day. The unique downward recoil system tames muzzle rise like nothing else, turning rapid strings into tight, controllable groups. It’s not just a compact firearm; it’s a physics lesson you can hold.
The Kriss Vector SBR Gen II 9mm 5.5″ Threaded Barrel Defiance M4 Stock with Adaptor Black 17rd All NFA Rules Apply is a compact, NFA-regulated short-barreled rifle built on the unique Kriss Vector delayed-blowback system. It features a 5.5-inch threaded barrel, accepts Glock-pattern magazines, and comes configured with a collapsible M4-style stock for a compact, adaptable package ideal for dynamic shooting and close-quarters use. Priced at $1358.85, it ships to Missouri and compliant US states.
Here’s the thing—the magic is in the Super V System. I’ve put a few hundred rounds of everything from 115gr FMJ to 147gr subs through this platform, and the felt recoil is genuinely different. Instead of driving straight back into your shoulder, the bolt carrier group redirects energy downward. The result? You stay on target faster for follow-up shots. It’s not just marketing; you feel it on the first mag.
The Gen II refinements are meaningful. The controls are more intuitive, the safety is ambidextrous, and the overall fit is solid. The included 17-round Glock magazine is a great start, but the beauty is the compatibility. This SBR runs on the vast ecosystem of Glock 17/19/19X/45 magazines, so sourcing reliable, high-capacity mags is easy and affordable. The 5.5-inch barrel is threaded 1/2×28, so adding a muzzle device or suppressor is drop-in ready—no gunsmithing required for most common attachments.

| Overall Length (Stock Collapsed) | Approx. 19.75 Inches |
| Weight (Unloaded) | Approx. 6.9 lbs |

Pros: The recoil mitigation is its standout feature, providing a flat-shooting experience that’s hard to match in this caliber. The compact form factor with the collapsible stock makes it incredibly handy. Magazine compatibility with ubiquitous Glock mags is a huge practical advantage. The build quality is robust, and the Gen II ergonomics are a significant step up.
Cons: It is an NFA item, meaning you must file a Form 4, pay the $200 tax stamp, and wait for approval before taking possession—this isn’t a point-of-sale purchase. The unique operating system makes it a bit wider than some traditional PCCs. At nearly 7 pounds unloaded, it’s not the lightest 9mm carbine out there, but that heft contributes to its stability.
So who is this for? It’s for the shooter who values performance and cool factor in equal measure. It’s perfect for the enthusiast who wants a supremely controllable, compact range toy or competition gun for PCC divisions that allow SBRs. It’s also a serious option for a home defense firearm where its compact size and low recoil are major assets, provided you navigate the NFA process. This isn’t a plinker for someone on a tight budget; it’s a purpose-built tool for someone who appreciates engineering.
Frequently Asked Questions
Q: What does “All NFA Rules Apply” mean for this purchase?
A: This Kriss Vector is configured as a Short-Barreled Rifle (SBR). Purchasing it requires filing an ATF Form 4, undergoing a background check, paying a $200 tax stamp, and waiting for approval (often several months) before your FFL can transfer it to you. FFL transfer required for firearm purchases.
Q: What magazines does it use?
A: It ships with one 17-round Kriss magazine, but it’s designed to use standard Glock-pattern magazines. You can reliably use magazines from Glock 17, 19, 19X, 34, and 45 models, giving you a wide range of capacity options from 10 to 33 rounds.
Q: Is the M4 stock adjustable?
A: Yes. The included Defiance stock is a six-position collapsible stock, allowing you to adjust the length of pull to fit your arm length and preferred shooting style, from fully collapsed for maximum maneuverability to extended for a more traditional rifle cheek weld.
