The distinction between the two locks is that the flintlock uses a single vertical sear to latch the cock in both the cocked and half-cocked positions. The sear is a lever that pivots in the vertical plane perpendicular to the axis of rotation of the cock and acts much like a pawl engaging the catch points of a ratchet gear .
The recoil operation is a type of locked-breech action used in semi-automatic and fully automatic firearms. It also uses energy from the combustion in the chamber acting directly on the bolt through the cartridge head, but in this case the firearm has a reciprocating barrel and breech assembly, combined with a bolt that locks to the breech.
Percussion caps have been manufactured in various sizes to fit snugly over different sized nipples. Nipples for 4.5mm and 6mm percussion caps. The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition.

[10] When released, a linear hammer, under spring pressure, slides along the bore axis rather than pivoting around a pin placed perpendicular to the bore, as with the more common rotating hammer.
