SAG Los-145 Chassis with AR Stock Adapter – M-LOK & ARCA Rail
CNC-Machined Aluminum | AR Mil-Spec Stock Base | M-LOK (3/6/9 o'clock) | Full-Length ARCA Rail | AR Grip Base | QD Ports | ?850 g
The SAG Los-145 Chassis (S20242) by Sureshot Armament Group is a precision chassis developed for Los-145 sporting carbines chambered in .308 Win / 9.6 Lancaster. This lightweight version features a base for an AR Mil-Spec stock, letting you fit the AR-pattern stock of your choice (the AR stock is not included).
The chassis provides an M-LOK interface on the handguard at 3, 6, and 9 o'clock, a full-length ARCA-RAIL interface, a base for an AR-pattern pistol grip (a SAG AR SL grip is included), and QD sling ports at 3 and 9 o'clock. Assembled weight is no more than 850 g, making it the lightest Los-145 chassis configuration.
? Installation Notes
- The AR stock is not included – select your own AR Mil-Spec stock.
- Fits all production years; carbines made after 2022 (rocking-type) must be installed in a gunsmith workshop.
- Bedding of the recoil-lug area is recommended during installation.
- For the Los-145 Taktika with a 336 mm barrel, installation must be done in a gunsmith workshop to ensure a total assembled length of at least 800 mm.
