Rs Regulate Vz-304 Vz 58 Rear-Biased Lower Rail

The RS Regulate VZ-304 is a rear-biased lower rail system engineered for VZ 58 rifles, solving one of the platform's biggest mounting headaches. If you run an AK-pattern rifle and want modern optics without the guesswork, this CNC-machined aluminum mount lets you dial in sight picture exactly where it needs to be—both front-to-back and left-to-right. Unlike one-size-fits-all mounts, the VZ-304's modular design accommodates three different lower-mount options, so whether you prefer a full-length rail, a forward placement, or this rear-biased configuration, you can optimize your optics position for your shooting style and rifle ergonomics.

Built from lightweight 6061 T6 aircraft-grade aluminum, the VZ-304 won't burden your rifle or slow you down whether you're at the range, in the field, or on an overland mission. The redesigned thumb-lever lock is rock-solid—it retains zero through repeated optic removal and reinstallation, a genuine concern when you're swapping glass or running different setups. The mount also plays well with VZ 58 field stripping; most variants can be broken down for cleaning without unmounting your optic, a practical touch when you're deep in the backcountry. For shooters running co-witness configurations, the rail positions glass for that sightline alignment. There's even a staking option built in for shooters who run their rifles hard and want maximum security.

RS Regulate engineered this mount with specific optic compatibility in mind: if you're mounting an Aimpoint T-1 or H-1 Micro, or a Trijicon ACOG system, the corresponding lower-mount options fit seamlessly. The attention to detail—from the proven thumb lever to the choice of rail placement—reflects the kind of thinking that separates a solid mount from one that merely bolts on.

Frequently Asked Questions

Will the VZ-304 work with my Aimpoint Micro optic?

Yes. The VZ-304 is engineered for Aimpoint T-1 and H-1 Micro mounting when paired with the corresponding lower-mount option. Confirm which lower-mount configuration suits your setup before ordering.

Can I remove my optic for cleaning or storage without taking the whole mount off?

Yes. The redesigned thumb-lever lock allows you to remove and reinstall your optic repeatedly while maintaining your zero. The mount itself stays mounted to the rifle.

Do I have to take off the optic to field-strip my VZ 58?

Not on most VZ 58 variants. The VZ-304 is designed to allow field stripping without optic removal, though compatibility may vary by specific rifle configuration.

What do the three lower-mount options do differently?

The full-length rail, forward rail, and rear rail options let you position your optics at different points along the receiver—front to back and left to right. This modular approach ensures you can dial in the ideal sight picture and mounting location for your shooting preferences and rifle setup.
