Custom 5.56 AR15 Rifle - Bad Attitude Long Branch Lower - Sig Tango MSR 1-6

A Custom-Tier Recce Architecture Pairing Fan-Favorite Clone Aesthetics with Premium Glass

This custom 5.56x45mm NATO rifle package is built around a unique, premium foundation designed by the specialized machinists at Bad Attitude Department. The lower receiver utilizes their highly sought-after "LOW-KEY" Long Branch Arsenal tribute profile, which features deep laser-engraved markings paying homage to iconic video game lore (the Fallout: New Vegas Service Rifle lineage). To maximize aesthetic cleanliness, all legal manufacturer branding is cleverly hidden out of sight underneath the trigger guard area, leaving a striking, uncluttered appearance across the magwell flats.

Mated smoothly to a Palmetto State Armory (PSA) upper assembly, this rifle is configured into a rugged, versatile "Recce-style" general-purpose carbine layout. Combining the definitive thermal stability of a full-length free-float quad rail handguard with a premium, smooth-tracking Faxon bolt carrier group and a fixed A2 buttstock, this platform is completely optimized for multi-range tracking, high-stress endurance, and repeatable shooting accuracy. To top it off, a custom “splatter” retro-theme camo pattern has been applied.

Condition and Action Highlights

Overall Status: Rated in excellent condition, showing pristine external presentation surfaces and displaying minimal mechanical track lines from light range use.

Upper Receiver and Barrel Assembly: The 16-inch 5.56 NATO factory upper receiver exhibits a unique splatter camo in a retro color scheme. Free of high-edge thinning or carrying scuffs, the barrel profile is nested perfectly within a heavy-duty, monolithic 13-inch free-float quad rail handguard. The full-length Picatinny rail channels are crisp, sharp, and free of mounting burrs, providing a rock-solid foundation for accessories.

Premium Sig Sauer Optic System: Mounted securely in an integrated factory alloy cantilever mount is a Sig Sauer Tango-MSR 1-6x24mm Low Power Variable Optic (LPVO). Highly favored by tactical marksmen, this premium glass package delivers true 1x performance for rapid, close-quarters target tracking, spinning seamlessly up to 6x power for medium-range precision. The multi-coated lenses offer exceptional light transmission, and the illuminated reticle breaks cleanly with edge-to-edge clarity.

High-Grade Faxon Internal Upgrades: Upgraded with a premium Faxon Firearms Bolt Carrier Group (BCG). Machined to demanding tolerances and finished in an ultra-slick, low-friction protective surface profile, this high-performance component ensures smooth mechanical tracking, reduced carbon adhesion, and effortless cleanup.

Lower Receiver and Stock Layout: The custom Bad Attitude Department tribute lower features Fallout: New Vegas themed markings. The system terminates in a traditional, full-length fixed A2 buttstock, offering an exceptionally stable cheek weld and a robust, proven length-of-pull balance.

Bore Presentation: The 16-inch barrel features a bright bore with sharp rifling, showing no erosion at the throat or crown.
