The head of the bolt on Marlin X7 rifles is separate from the bolt body. This allows it some flexibility to positively align with the cartridge when chambered.
The user-adjustable Marlin Pro-Fire trigger increases the shootability of Marlin X7 rifles and considering what aftermarket triggers cost, it is a true bargain.
The safety on the Marlin X7 is located on the right side of the action. There is also an indicator just under the bolt shroud that signals if the action is cocked.
