Building and selling rifles using Aero Precision components can be profitable, but success depends on several factors. Aero Precision parts, available at AR15Discounts.com (https://ar15discounts.com/brands/aero-precision/), are priced competitively, offering quality at a lower cost than some brands, which can lead to decent profit margins. Profitability requires managing costs, including components, tools, labor, and licensing. Federal law requires a Federal Firearms License (FFL) for manufacturing firearms for sale, and state regulations may add requirements. Market demand, competition, and customization affect profits; specialized builds using Aero’s M4E1 or M5 platforms may fetch higher prices. Builders must also cover marketing, distribution, and compliance costs. With careful planning, Aero Precision components can support a profitable venture, especially for niche markets.
Aero Precision is a respected brand, known for producing reliable, American-made AR parts at fair prices. Their aerospace background, use of U.S.-sourced materials, and modern manufacturing produce components with solid precision and durability. Products like the M4E1, M5, and EPC-9, available at AR15Discounts.com, show their focus on innovation, with features that ease assembly and improve performance. Serving both builders and OEMs, Aero Precision’s reputation for value and reliability makes it a strong choice for AR projects, praised for quality and affordability.
Aero Precision barrels are mainly made in-house or by their sister company, Ballistic Advantage, acquired in 2014. Available at AR15Discounts.com, these barrels use 4150 chrome moly vanadium or 416R stainless steel, depending on the caliber. They undergo high-pressure testing and magnetic particle inspection for safety and accuracy. Ballistic Advantage’s expertise ensures match-grade barrels, like the 16-inch .223 Wylde or .300 Blackout models, deliver sub-MOA accuracy with proper ammunition.
Aero Precision uppers are well-regarded for their machining, materials, and design. Models like the M4E1 Threaded PRO 13.7″ CHF 5.56 M-LOK Midlength Complete Upper at AR15Discounts.com (https://ar15discounts.com/brands/aero-precision/) feature cold hammer-forged barrels for accuracy and QPQ nitride coatings for longevity. Forged from 7075-T6 aluminum, these uppers ensure strength and fit with mil-spec lowers. The M4E1’s integrated barrel nut system simplifies assembly while supporting a free-float handguard for better accuracy. They’re a solid choice for tactical, competitive, or recreational builds.
Aero Precision does not own Stag Arms. Both operate independently, with Aero Precision based in Tacoma, Washington, focusing on AR-15 and AR-10 components, and Stag Arms specializing in complete rifles and parts under separate ownership. There is no corporate affiliation, as confirmed by Aero Precision’s resources and industry records.
Aero Precision lowers, like the M4E1 and Gen 2 models at AR15Discounts.com, are valued for their quality. Forged from 7075-T6 aluminum, they meet mil-spec standards with tighter tolerances for a precise fit with uppers. The M4E1 lower has an integrated trigger guard, threaded bolt catch pin, and flared magwell, easing assembly and improving function. These features, paired with Aero’s durability and affordability, make their lowers a top pick for AR-15 or AR-10 builds.
Aero Precision focuses on components rather than complete rifles, but their parts, like those in the M4E1 and M5 platforms at AR15Discounts.com, enable high-quality builds. These include match-grade barrels, precise tolerances, and features like ambidextrous controls. When assembled with care, Aero Precision-based rifles perform reliably for tactical, competitive, or recreational use, offering value and performance comparable to premium brands.
To remove an Aero Precision handguard, such as the MOD 4 M-LOK or ATLAS models at AR15Discounts.com, ensure the rifle is unloaded. For ATLAS handguards, use the provided tool to loosen the turnbuckle screw at the rear notch, stabilizing the taper lock assembly as the tapered nuts disengage. If resistant, a light tap with a nylon hammer may help. Slide the handguard off the barrel nut, using lubricant and a slight twist if it binds. For the MOD 4, loosen the barrel nut screws after removing accessories, then slide it off. Consult Aero Precision’s instructions for specific models, as mounting systems vary.
Aero Precision manufactures its bolt carrier groups (BCGs) in-house. Available at AR15Discounts.com (https://ar15discounts.com/brands/aero-precision/), BCGs like the 5.56/.223 in black nitride or nickel boron are machined from 8620 steel (carrier) and 9310 steel (bolt), with high-pressure testing and magnetic particle inspection for reliability. Used in M4E1 and M5 uppers, they ensure consistent cycling and durability for AR-15 and AR-10 builds.
Aero Precision barrels, available at AR15Discounts.com, are not typically chrome lined. They use 4150 chrome moly vanadium or 416R stainless steel with a QPQ nitride coating, as seen in the 16-inch .223 Wylde or .300 Blackout barrels. This coating offers corrosion resistance and durability similar to or better than chrome lining, while preserving accuracy in match-grade barrels. Chrome lining can reduce precision, making QPQ nitride Aero’s choice for performance.
Some Aero Precision barrels are cold hammer forged (CHF), particularly in the PRO series, like the M4E1 Threaded PRO 13.7″ CHF 5.56 upper at AR15Discounts.com. CHF barrels, made from 4150 chrome moly vanadium steel, are forged around a mandrel for durability and precision, achieving sub-MOA accuracy. Other barrels, like the 16-inch .223 Wylde, use conventional machining but are rigorously tested. Check product listings for CHF designation.
Aero Precision lowers, such as the M4E1 and Gen 2 models at AR15Discounts.com, feature a low-shelf design in their fire control group pocket, allowing compatibility with registered drop-in auto sears (for law enforcement or NFA-registered firearms), though civilian builds use semi-automatic triggers. This ensures versatility while maintaining mil-spec standards.
Aero Precision lowers, including the M4E1, Gen 2, and M5 .308 at AR15Discounts.com, are mil-spec, adhering to military standards for dimensions, materials (7075-T6 aluminum), and compatibility with standard AR-15 or AR-10 components. Their machining achieves tighter tolerances, enhancing fit and performance while preserving mil-spec compatibility.
Aero Precision does not produce or sell 80% lowers, which are partially machined receivers not classified as firearms by the ATF. Their lowers, like the M4E1 and M5 at AR15Discounts.com, are fully machined, serialized, and require FFL transfer, aligning with Aero’s focus on completed, compliant components.
To complete an M4E1 upper, like the M4E1 Threaded Stripped Upper at AR15Discounts.com, you need an upper parts kit (dust cover and forward assist), bolt carrier group, charging handle, barrel, muzzle device, gas tube, gas block, and handguard. Ensure the rifle is unloaded, install the parts kit, attach the barrel with the nut, add the gas block and tube, secure the muzzle device, and mount the handguard (e.g., MOD 4 M-LOK). Verify torque and alignment per Aero Precision’s instructions.
