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 | approx. 850 g
Overview
The S20242 is the same Los-145 chassis as the S20243 with one change: the rear takes an AR Mil-Spec stock base rather than a fitted adjustable stock. If you already own an AR stock you like, this is the version that lets you use it - and the assembled weight drops to about 850 g.
The handguard carries M-LOK at 3, 6 and 9 o'clock and a full-length ARCA-RAIL beneath, so the carbine clamps directly onto an ARCA tripod head or bench rest at any point along its length. QD sling ports sit at 3 and 9 o'clock.
The SAG AR SL sidearm grip is included, and the grip base is AR-pattern so any AR grip can take its place. It fits Los-145 sporting carbines in .308 Win and 9.6 Lancaster across all production years. The AR buffer tube and stock are not included.
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 specialist 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 specialist workshop to ensure a total assembled length of at least 800 mm.
