A 16" 350 Legend AR15 barrel with a 1:16 twist, nitride finish, 41V50 carbine length gas system, and 5/8x24 muzzle threads.
Pillar installation assists in accuracy as it prevents crushing of the stock and prevent stress cracks. Pillars also keep the action from twisting or moving. Consistency is key in accuracy.
Please ask any and all questions before buying. I am a one man operation machining these pillar kits. I conduct all business with respect, and try to be as professional as possible. I appreciate the same. If something happens please offer a little grace and understanding and contact me about any issues.
Never work on a loaded firearm. Always follow safe practices and ensure the fire arm is unloaded before beginning any work.
