looks solid but definitely not 1/2x28 by Kyle Abbott, Verified Owner, March 4, 2025
5/8x24 thread pitch….machine work looks clean on everything…rifling looks perfect and fitment to upper has zero slop. I’m really impressed. Picked up on sale from DVOR for under $100 and it definitely beats bca and ballistic advantage
