These parts came off of a manufacturer assembled Aeroprecision AR and were removed by a professional gunsmith. They are in like-new condition. Includes: - Standard Front Sight/Gas block (fits 0.750" diameter) - Gas block mounting pins (the two longer pins - see pictures) - Gas tube pin (gas tube NOT included unfortunately....) - Handguard/heatguard & front plate - Barrel Nut Assembly (as it came from the factory - never disassembled) Asking $50 for it all. Local deals only. Cash only. Texting works best for me. Thank you for looking!
