1000 Yard 6 ARC Gas Gun Dream Build Kit – Long-Range AR-15 Precision Build
Features
- Long-range AR-15 parts kit built around the flat-shooting 6 ARC cartridge
- 20″ 6 ARC target barrel supports higher velocity and stronger downrange performance from the AR-15 platform
- Rifle-length gas system and Superlative Arms adjustable gas block allow tuning for smoother cycling
- STNGR 15.5″ VLCN M-LOK handguard provides extended support-hand space and accessory mounting
- Faxon 6.5 Grendel Type 2 bolt carrier group supports proper 6 ARC bolt compatibility
- Vortex Viper PST Gen II 5-25×50 FFP scope gives the rifle a capable precision optic package
- Arisaka offset optic mount and AT3 ACE red dot add a secondary close-range sighting option
- Ballistic Engineering GOAT 2-stage trigger provides a more precise trigger setup for distance shooting
- Magpul bipod and ARCA rail adapter support prone, bench, and supported-position shooting
This 1000 Yard 6 ARC Gas Gun Dream Build Kit is built for shooters who want to stretch the AR-15 platform past typical 5.56 distances without stepping up to a larger-frame rifle. The 20″ 6 ARC barrel, rifle-length gas system, adjustable gas block, and 2-stage trigger give the build a strong precision foundation, while the Vortex 5-25x FFP optic provides the magnification and reticle setup expected on a long-range gas gun. An offset red dot, extended controls, bipod, and ARCA support round out the rifle for practical use from supported positions.
Note: This kit is based on the 1000 Yard 6 ARC Gas Gun Dream Build configuration. Final assembly is up to you. Parts and accessories are subject to change due to unforeseen shortages or compliance changes. Any alterations will be of equal or greater value and will be noted in this product listing.
