Aero Precision X15 5.56 NATO AR-15 Custom Build – 16.5 in Threaded Barrel, ATLAS S-ONE M-LOK, Magpul MOE Stock, Flip-Up Sights
This custom-configured Aero Precision X15 pairs a 16.5-inch threaded barrel with Aero's lightweight ATLAS S-ONE free-float M-LOK handguard and Magpul furniture. It comes ready with installed polymer flip-up sights and a Magpul MVG vertical foregrip. The hard-anodized 7075-T6 receiver set is US-made, with Aero markings from Lakewood, WA on the receiver and Tacoma, WA on the handguard. The bore is excellent, and one 30-round PMAG is included.
The direct-impingement upper includes a forward assist, case deflector, and ejection-port cover. A continuous Picatinny rail runs across the upper, and the slim ATLAS S-ONE handguard provides M-LOK mounting slots. The knurled thread protector is installed on the threaded muzzle; no muzzle device is installed.
Magpul MOE Carbine Stock hardware delivers an adjustable, collapsible setup with an approximate 10.5–13.5 inch length of pull. An A2-style polymer pistol grip and an installed Magpul MVG vertical foregrip round out the controls and handling. A manual safety selector is present.
The lower is marked MODEL X15 and CAL MULTI with Aero's logo and SAFE/FIRE pictograms. Chambered in 5.56 NATO with a 30+1 capacity, this build is a straightforward, quality Aero Precision configuration with installed backup sights and durable materials throughout.
