SAG MK3 SLIM Chassis - 7-Slot M-LOK with Rear Sight Cutout

In short: The 7-slot MK3 SLIM: a slim free-float chassis with a longer M-LOK handguard and a rear sight cutout that retains the factory rear sight.

Overview

The 7-slot MK3 SLIM is the longer of the two rear-sight-cutout SLIM chassis. Three extra M-LOK slots per side is the difference between placing a bipod, a hand stop and a light where you want them and having to compromise on one of them.

The handguard is slim in profile and the barrel free-floats inside it, so bipod load and grip pressure stop moving the point of impact. The rear sight cutout keeps the factory rear sight in service as a backup behind an optic.

The top rail is a continuous 1913-MIL-STD monorail from the gas block to the shortened cover, with an additional 1913 segment on the removable rear cover. CNC-milled high-strength aluminum alloy with steel inserts and fasteners; the chassis can be moved to another carbine later. The shorter version is the S20050.

Installation Note

Installation requires removing the factory handguard ferrule. This chassis is not suitable for self-installation on full-size carbines built on certain Molot Arms AK-pattern receivers (MA-136-02, MA-136C, MA-136-05); those require a specialist workshop. Install in accordance with the manual.

Frequently Asked Questions

What does the rear sight cutout do?

It preserves the factory rear sight so you keep your iron sights after installing the chassis.

How is the 7-slot different from the 4-slot SLIM?

The 7-slot handguard is longer, giving you more M-LOK mounting length for accessories.

Does it free-float the barrel?

Yes - the chassis free-floats the barrel inside a tubular handguard.

Do I need a specialist?

Most installs require only removing the handguard ferrule. Certain Molot Arms AK-pattern full-size carbines require a specialist workshop.
