There is a small square button just in front of\nthe trigger,inside the trigger guard. If your\nparticular rifle is the BDL grade there is also\na magizine floor plate release just inside the\nfront of the trigger guard. The floor plate release will allow you to unload the magizne\nwell without cycling the bolt This button, if\nequipped, is half-moon shaped and thin like\na dime.

just buy the swivel set from a walmart supercenter.  i think the brand is uncle mike's.  if the hole in the front is too small, just drill it out.  use loctite on the nut.

a Screw usually has threading, a Bolt usually doesn't. Actually, a Screw is shorter than a bolt.

pretty much all the muscle found in your arm are involved and the deltoid, and same with the never. But you also have to consider the nerves that send the information to the brain.

Archimedes is credited with inventing the screw in the 3rd century BC.  An example of a screw working as a machine is, coincidentally, the Archimedean Screw.\n\nThere are many different kinds of screws. See the second source below for some examples.

Ok, just from memory, some of the main muscles are:\nSerratus, trapezius, rhomboids, levator scapulae: these keep the scapula in place and rotate it.\nDeltoids, teres, part of the triceps: they move the humerus.\nSupraspinatus, infraspinatus, subscapularis: these keep the humeral head in place and help move the humerus.\nThere are other muscles and some of the ones I mentioned may be differentiated into different parts.
