The AR 10A is a member of ArmaLite’s AR 10 family of semi-automatic rifles chambered in .308 / 7.62×51 NATO. It differs from the AR 10B by magazine compatibility: the AR 10A accepts early ArmaLite waffle magazines and PMAG-style magazines, whereas the AR 10B uses proprietary aluminum magazines. The AR 10A and AR 10B share many operating features but are not magazine-compatible with each other.
Technical details:
- Caliber: .308 Winchester / 7.62×51 NATO
- Barrel length: Often 20" on match / Super SASS variants; some tactical versions use shorter (e.g. 16") barrels
- Twist rate: Varies by model, e.g. 1:10 on the Super SASS version
- Action: Semi-automatic, gas-operated with rotating bolt
- Magazine capacity: Commonly 20-round magazines
- Stock / Handguard / Rails: Free-floating or quad-rail handguards are common; adjustable stocks and full-length rails for optics
