Purchase AR rifles online or visit the gun shop in Llano, Texas to shoulder different configurations, compare handguard lengths, and test trigger pulls before committing. Inman’s Armory serves customers in the nearby cities of Burnet, Marble Falls, Fredericksburg, Austin, and San Antonio, stocking modern sporting rifles for home defense, training, three-gun competition, and predator hunting across the Texas Hill Country.
Federal law requires AR rifle buyers to be at least 18 years old when purchasing a long gun from a licensed dealer, and Texas requires the standard NICS background check at the point of sale through any FFL transfer. Buyers must complete ATF Form 4473 at the time of transfer, and any disqualifying factors under federal or state law will block the sale. Texas does not impose a state-level assault weapons ban, magazine capacity limit, or registration requirement for AR-platform rifles.
Transport AR rifles unloaded in a case during travel, with magazines stored separately when practical, and review Texas Parks and Wildlife rules for any caliber or projectile restrictions during big game seasons. Store AR-platform rifles in a secure cabinet or safe when not in use, and contact the shop with questions about availability, transfers from out-of-state dealers, or special-order configurations.
AR stands for ArmaLite Rifle, named after the company that originally designed the platform in the late 1950s. It does not stand for “assault rifle” or “automatic rifle” as is sometimes incorrectly assumed.
5.56 NATO is loaded to higher chamber pressures and uses a slightly longer throat than .223 Remington. Rifles marked 5.56 NATO can safely fire both, while rifles marked .223 Remington only should not be used with 5.56 NATO ammunition.
16-inch barrels are the standard for general-purpose AR rifles, balancing maneuverability with full velocity from 5.56 NATO loads. 18 to 20 inch barrels favor longer-range precision, while 14.5 inch barrels (with pinned and welded muzzle devices to reach 16 inches) offer slightly better handling for defensive use.
Bolt carrier groups themselves are durable and often last tens of thousands of rounds with proper maintenance, but specific components like extractors, ejectors, gas rings, and the bolt itself benefit from periodic inspection and replacement. Many shooters replace bolts around the 6,000 to 10,000 round mark depending on caliber and use.
Direct impingement systems route propellant gas directly into the bolt carrier to cycle the action, keeping the rifle lightweight but introducing carbon and heat into the receiver. Piston-driven systems use a separate operating rod to cycle the action, running cooler and cleaner at the cost of added weight and a different recoil impulse.
Yes, AR pistols and AR rifles can use the same lower receiver, but the firearm’s classification is determined by the original configuration as recorded on the ATF Form 4473 at first sale. Converting between configurations after the fact must follow specific federal rules to avoid creating an unregistered short-barreled rifle.
A free-float handguard attaches only to the upper receiver and does not contact the barrel, which preserves accuracy by preventing handguard pressure from affecting barrel harmonics. Most modern AR rifles use M-LOK or KeyMod free-float handguards for both accuracy and accessory mounting flexibility.
AR-platform rifles are legal to purchase, own, and use in Texas for buyers who meet federal and state eligibility requirements, with no state-level ban on the platform or standard-capacity magazines. Buyers must complete the required NICS background check and ATF Form 4473 at a licensed dealer.
