SAG Los-145 Chassis with Adjustable Stock - M-LOK & ARCA Rail
CNC-Machined Aluminum | Fully Adjustable Stock | M-LOK (3/6/9 o'clock) | Full-Length ARCA Rail | AR Grip Base | QD Ports | approx. 1240 g
Overview
The S20243 turns a Los-145 sporting carbine in .308 Win or 9.6 Lancaster into a chassis carbine. It arrives complete: chassis, fully adjustable stock, and the SAG AR SL sidearm grip, with the mounting hardware and manual in the box.
The handguard carries M-LOK at 3, 6 and 9 o'clock and a full-length ARCA-RAIL underneath. ARCA is what makes the difference on a bench or a tripod - the carbine slides directly into an ARCA clamp and locks anywhere along its length, no adapter plate required. QD sling ports sit at 3 and 9 o'clock.
The stock adjusts for length of pull and comb height, so the chassis fits the shooter rather than the other way round. The grip base is AR-pattern, so any AR-pattern grip can replace the supplied SL grip. Assembled weight is about 1240 g. It fits Los-145 carbines of all production years. A lighter version without the adjustable stock, taking an AR stock instead, is the S20242.
Installation Notes
- 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.
