    Best on the market and pure quality! This makes my forth IP action, and I’ve no problems what so ever with it! Great product for all precision and hunting needs! Will be buying a few more this year for my builds! Don’t settle for less, “Buy once, cry once,” and it will be the best investment for your money when building your gun!
