Semi-Auto Rifles
Semi-automatic rifles cover the widest range of uses in the modern firearms market — from the ubiquitous AR-15 used for home defense, competition, and varmint hunting, to pistol-caliber carbines ideal for suppressed use, to semi-automatic hunting rifles that bring faster follow-up shots to deer and hog fields. Impact Guns stocks hundreds of semi-automatic rifle configurations across every major platform, caliber, and price point.

AR-15: America’s Most Popular Semi-Auto Rifle
The AR-15 is the most widely owned semi-automatic rifle in the United States — a direct-impingement or piston-operated design chambered primarily in 5.56 NATO/.223 Rem, with options in .300 Blackout, 6.5 Grendel, .350 Legend, and more. Its modular design means every component is replaceable and upgradeable, making it the most customizable platform available. Entry-level AR-15s from Ruger and Anderson Manufacturing start under $600. Premium builds from Daniel Defense and Noveske run $1,500–$2,500. The AR-15’s deep aftermarket, wide ammunition availability, and proven reliability make it the default answer for most semi-auto rifle buyers.
AK-47 Platform: Reliability in Any Condition
The AK-47 and its variants fire 7.62x39 — a heavier bullet than 5.56 that delivers more energy at close to moderate range with a distinctively different recoil impulse. The AK platform is renowned for reliability under adverse conditions: mud, sand, and neglect that would stop an AR-15 rarely affect a properly built AK. Modern American-made AKs from Century Arms (WASR-10), Zastava (ZPAP series), and Riley Defense offer quality builds at accessible prices. For buyers who want a reliable semi-auto rifle chambered in a hard-hitting cartridge with lower cost-per-round than premium AR calibers, the AK platform is a compelling choice.
Pistol-Caliber Carbines: 9mm Semi-Auto Rifles
Pistol-caliber carbines (PCCs) fire handgun cartridges — most commonly 9mm — from a rifle-format platform. The benefits are threefold: lower recoil than rifle calibers, hearing-safe when suppressed with subsonic ammunition, and in many states, sharing magazines with a 9mm pistol. The CZ Scorpion EVO 3 is the most popular PCC. The Ruger PC Carbine accepts Glock magazines. The Kel-Tec Sub-2000 folds in half for storage. For a home defense or suppressor-host semi-auto rifle, a 9mm PCC is one of the most practical choices available.
Semi-Auto Hunting Rifles: Browning BAR, Ruger & More
Semi-automatic hunting rifles bring faster follow-up shots to the field at the cost of slightly more weight and complexity vs. bolt-actions. The Browning BAR (in .308, .30-06, and magnum calibers) is the gold standard — gas-operated, accurate, and beautifully finished. Ruger’s Ranch Rifle series in .450 Bushmaster and .350 Legend covers straight-wall cartridge states. The Ruger Mini-14 in 5.56 and Mini Thirty in 7.62x39 cover varmint and deer hunting with traditional aesthetics. For dangerous game follow-up shots or hunting where the first shot may not connect, a semi-auto hunting rifle justifies its place.
Semi-Auto Rifle Calibers: Matching Platform to Purpose
Caliber choice drives the platform decision. For varmints and home defense: 5.56 NATO in an AR-15. For deer at moderate range: .308 Win, 6.5 Creedmoor, or .30-06 in a hunting semi-auto. For suppressed use: .300 Blackout or 9mm PCC. For large game and hogs: 7.62x39 AK or .450 Bushmaster in an AR-platform. For maximum versatility in a single platform, the AR-15 in 5.56 with the option to swap uppers covers the widest range of applications. Match caliber to your primary intended use before selecting a platform.
