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
The SAG MK1 M-LOK Chassis (S20051) by Sureshot Armament Group is a complete solution for mounting day and night optic systems, rangefinders, and target-illumination devices on side-rail marksman sporting platforms. CNC-milled from high-strength aluminum alloy, with the barrel sleeve and all insert elements machined from steel.
The chassis free-floats the barrel and provides a monolithic 465 mm 1913-MIL-STD rail at 20 MOA that does not require removal for field-stripping. The extended M-LOK handguard is 60 mm longer than the original, and resting on it does not shift your point of impact.
? Professional Installation Required
This chassis must be installed in a certified gunsmith 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
- Free-floats the barrel - for improved consistency and accuracy potential
- Monolithic 465 mm 1913 rail at 20 MOA - for day/night optics, rangefinders, illuminators
- No removal for cleaning - rail stays on during field-stripping
- Extended M-LOK handguard - 60 mm longer than original, no point-of-impact shift when supported
- Steel barrel sleeve & inserts - durable, repeatable
- Aluminum body - strong and lightweight
