SAG MK1 M-LOK Chassis for Marksman Platforms - Free-Float 1913 Rail
CNC-Machined Aluminum | Steel Barrel Sleeve | Free-Floating Barrel | 465 mm 1913 Monorail | 20 MOA | M-LOK Handguard
Overview
The S20051 is the chassis for owners who intend to use their marksman platform at distance. The top rail is monolithic - one piece of aluminum, 465 mm long - and built with 20 MOA of cant, which returns roughly twenty minutes of elevation to the scope for use at range instead of at zero.
The handguard is M-LOK and runs 60 mm longer than the original, giving room to place a bipod, a hand stop or a sling mount where the shooter wants them rather than where the factory furniture allowed. A steel barrel sleeve and steel inserts carry the loads that aluminum should not.
The barrel free-floats, so resting the handguard on a bag or loading a bipod does not shift point of impact. The rail stays on the carbine for field-stripping. Installation is a job for a certified specialist, not a home fitting.
Professional Installation Required
This chassis must be installed in a certified specialist workshop, in accordance with the manual.
Important: On the TG-3 / Tiger 308 platform, the barrel is pinned in the receiver. During installation, take special care that the pin ensuring the barrel-to-receiver connection is not disturbed.
Key Advantages
