It’s not the newest combat rifle in America’s arsenal, but the FN SCAR now has more than a decade of combat service under its belt to earn it a spot on this list. Introduced in 2009, the rugged and modular SCAR family features a gas-operated, short-stroke gas piston.
FN built the SCAR to fit the requirements of U.S. Special Operations Command during the Global War on Terror. The SCAR family can be broadly broken down into light and heavy variants, chambered for 5.56 NATO and 7.62 NATO, respectively. Options for 6.5 Creedmoor and .300 BLK are also available.

New-production commercial SCAR variants from FN include the SCAR 16S in 5.56 NATO, the SCAR 17S in 7.62 NATO, the SCAR 20S in 6.5 Creedmoor and 7.62 NATO, and the extra-compact SCAR 15P large-format pistol. Alas, like the Steyr AUG and the IWI Tavor, commercial SCAR clones are currently best had from the original maker.
While not certainly clones, per se, there are SCAR alternatives that have a lot of the same aesthetics and modular qualities, if not the same technical parts and function. Such is the case with the Bushmaster ACR and CZ Bren 2, which both offer SCAR-ish looks and short-stroke gas piston systems. A similar visual comparison could be made about the PSA Jackl, but that gun features a long-stroke gas piston.
