Frequently Asked Questions

What was the Sterling LAR?

The Sterling LAR (Light Automatic Rifle) was a British firearm developed by Sterling Armaments as a derivative of the ArmaLite AR-18 design. It aimed to leverage the AR-18's stamped steel construction while introducing modifications to circumvent ArmaLite's patents.

Why was the Sterling LAR developed?

The Sterling LAR was created to bypass ArmaLite's patents on the AR-18 design. Sterling Armaments licensed the AR-18 but couldn't sub-license it, so they developed the LAR as a 'legally different' firearm, leading to unique design choices.

What were the key features of the Sterling LAR?

Key features included stamped sheet steel construction, a complex folding stock mechanism, an adjustable gas regulator, and an experimental three-round burst mechanism utilizing a triangular roller cam. It was chambered in 5.56x45mm.

Was the Sterling LAR successful?

No, the Sterling LAR was not commercially successful. It remained a prototype and never entered mass production, failing to find any significant buyers despite its innovative (though sometimes compromised) design elements.
