Perfect fit and easy to adjust even with my Acme hand guard in place. It solved my rifles over-gassed problems. I recommend this product.
Works well. headspace GTG . Staked properly, and the nitride finish is slicker than eel snot. I watched the you tube video of the manufacturing process. Very cool. Fast shipping and courteous service with prompt communication . Last but not least the cost was very competitive. Thank you, Respectfully, David , PSL, FL
