Lancer LCS Carbon Fiber Stock LCS-A1-R (also known as the Lancer Systems LCS-A1-R Fixed Carbon Fiber Buttstock, A1 Length).
This is the A1-length version of Lancer's premium fixed carbon fiber stock, designed for AR-15 and AR-10 platforms. It delivers an ultra-lightweight fixed-length solution tailored for competition shooters, precision builders, and anyone prioritizing minimal weight, excellent balance, and a comfortable cheek weld without the added mass or moving parts of an adjustable stock. It installs on a standard rifle-length buffer tube (not included).
Key Features & Specs
- Length: A1 configuration — 10.25 inches (shorter length of pull compared to A2).
- Weight: Approximately 9.4 oz (some sources list 9.44 oz or 285g / 10.05 oz; extremely light for a fixed stock).
- Construction: High-strength carbon fiber tube with a custom ergonomic profile for a solid, comfortable cheek weld. Impact-resistant injection-molded polymer buttplate and front collar for durability and recoil absorption. Features a unique carbon fiber layup/resin combination for toughness.
- Mounting: Fixed design for rifle-length buffer tubes. Compatible with standard AR-15/AR-10 lower receivers and most mil-spec or commercial rifle extensions. Drop-in installation (simple and rattle-free).
- Additional Features:
- Integrated QD sling mount (quick-detach sling point).
- 3 sling points total for versatile carry options.
- Streamlined, modern look with no flex or play.
- Benefits: Dramatically reduces overall rifle weight for faster handling, reduced fatigue, and better balance — especially useful on lightweight builds, competition rifles (3-Gun, PRS), or hunting setups. The fixed design ensures consistent length of pull (LOP) and rock-solid lockup.
The LCS-A1-R is praised for its comfortable cheek weld (narrower comb than some SOPMOD-style stocks), rigidity, and how it makes the rifle feel more agile without sacrificing durability. It's ideal when you want a consistent, no-adjustment stock that shaves significant ounces compared to traditional polymer or aluminum fixed stocks.
Who It's For
- Competition and speed shooters who prefer a fixed, lightweight stock.
- AR builders creating ultra-light or well-balanced rifles (pairs great with carbon fiber handguards or lightweight barrels).
- Users who value simplicity and reliability over adjustability.
Note: Requires a rifle-length buffer tube and buffer (not included). Not compatible with carbine-length tubes.
