16. The firearm of claim 14 wherein:

the second actuation section is disposed on a side of the barrel approximately 90 degrees from the first actuation section.

17. The firearm of claim 14 wherein:

the first actuation section and the second actuation section are discrete components of the hand-held actuation member.

18. The firearm of claim 14 wherein:

the pump-action actuation member comprises a third actuation section.

19. The firearm of claim 18 wherein:

the handguard comprises a third actuation section travel slot; and

the third actuation section is configured to travel within the third actuation section travel slot during the reloading of the firearm.

20. The firearm of claim 18 wherein:

the third actuation section is disposed on a side of the barrel approximately 180 degrees from the second actuation section.

21. The firearm of claim 17 wherein:

the first actuation section, the second actuation section and the third actuation section are discrete components of the hand-held actuation member.

22. The firearm of claim 1 wherein:

the firearm is a rifle.

23. The firearm of claim 1 further comprising:

a bolt and a bolt carrier; and

wherein, during operation of the firearm, the bolt is locked with the barrel.

24. The firearm of claim 1 further comprising:

a detachable magazine.

25. The firearm of claim 1 further comprising:

a bolt carrier; and

a bolt carrier locking mechanism arranged to inhibit the bolt carrier from rearward travel while an unfired cartridge is located in a chamber of the barrel.

26. The firearm of claim 25 wherein:

the bolt carrier locking mechanism comprises a bolt carrier locking member; and

the bolt carrier locking member is movable transverse to a longitudinal axis of the bolt carrier.

27. The firearm of claim 26 further comprising:

a firing hammer; and

the firing hammer and the bolt carrier locking member are arranged such that the bolt carrier locking member is arranged to move transverse to the longitudinal axis of the bolt carrier and out of alignment with the firing hammer in response to being contacted by the firing hammer.

28. The firearm of claim 27 wherein:

the bolt carrier locking mechanism comprises a spring; and

the bolt carrier locking member and the spring are arranged such that a transverse movement of the bolt carrier locking member in response to being contacted by the firing hammer is biased by the spring.
