Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs.

⚠ SHORT BARRELED RIFLE — NO FORM 4 REQUIRED Since October 9, 2026, ATF no longer requires a Form 4, tax stamp, fingerprints or registration for short-barreled rifles. It transfers on a standard Form 4473 with a NICS background check. Your state’s law still applies, and taking one across state lines still needs an approved ATF Form 5320.20. Outside Texas, we ship to an SOT dealer in your state. What changed · How buying one works now
The KRISS Vector SBR G3 uses the Super V operating system — the bolt carrier moves at 45 degrees downward on firing, redirecting recoil energy downward instead of rearward, producing dramatically flatter muzzle rise than any conventional PCC. The G3 is KRISS’s third-generation refinement of this unique platform.
Caliber: 9mm Luger. 9mm Luger: affordable, widely available, compatible with subsonic loads for suppressor use. Finish: AD. AD anodized finish.

FAQ — KRISS Vector SBR G3
How does the Super V system reduce felt recoil?
The Super V BCG travels at 45 degrees downward, converting rearward recoil impulse into downward force. This pushes the front of the rifle down rather than the muzzle up. Net effect: dramatically flatter recoil than any conventional blowback PCC.
Can the Vector SBR be suppressed?
Yes — the 5.5″ barrel is threaded. Suppressed subsonic 9mm or 10mm on the Vector platform is one of the most unusual NFA combinations available.
