A stock for a firearm is disclosed. The stock has a length of pull (LOP) adjustment mechanism. The LOP adjustment mechanism is biased towards an engaged configuration and is movable to a disengaged configuration. A locating member protrudes into a stock mounting space and a first arm is in an engagement position when the LOP adjustment mechanism is in the engaged configuration. The locating member is translated such that the locating member does not protrude into the mounting space and the first arm is pivoted into a disengagement position when the LOP adjustment mechanism is in the disengaged configuration.

1. A length of pull mechanism for a firearm stock, comprising: a locating member translatably coupled to a housing;a first lever having a receiving component contact surface;a second lever coupled to the first lever and having a receiving component contact surface; andand a transverse member one of coupled or integrated to the locating member and extending towards first and second sides of a length of pull mechanism; whereinthe first lever and the second lever pivotally engage a transverse mount in the housing whereby the first and second levers are configured to pivot about a pivot axis;the first and second levers are pivotable towards engagement with the transverse member; andthe transverse member is shaped to translate pivoting motion of the first and second levers into a translational movement of the locating member; whereinthe first and second levers are configured to engage a receiving component of a firearm having the firearm stock, the receiving component of the firearm manufactured within a minimum tolerance stack-up and a maximum tolerance stack-up;a distal end of the first lever is configured to abut the receiving component when the length of pull adjustment mechanism is in an engaged configuration and the receiving component has the minimum tolerance stack-up; andthe distal end of the first lever is configured to disengage from the firearm when the length of pull adjustment mechanism is in a disengaged configuration and the receiving component has the maximum tolerance stack-up. 2. The mechanism of claim 1, wherein: the receiving component contact surfaces are curved surfaces shaped to engage the receiving component of the firearm. 3. The mechanism of claim 1, wherein: the mechanism comprises the engaged configuration wherein the levers are pivoted in a first direction, and a top portion of the locating member is translated up; andthe mechanism comprises the disengaged configuration wherein the levers are pivoted in a second direction different from the first direction, and the locating member is translated down. 4. The mechanism of claim 3, wherein: the mechanism is configured to pivotally couple to the housing;the housing is a housing of the firearm having the receiving component;the receiving component contact surfaces of the levers are configured to abut the receiving component when the mechanism is moved towards the engaged configuration; andthe locating member does not bottom out against the receiving component in the engaged configuration. 5. The mechanism of claim 4, wherein: the transverse member is a cylindrical pin without a notch. 6. The mechanism of claim 4, wherein: the transverse member extends between the second lever and the first lever, the transverse member slidingly engaged with the second lever and the first lever. 7. The mechanism of claim 1, wherein: the distal end of the first lever and the locating member are configured to prevent unintentional disengagement when the receiving component has the maximum tolerance stack-up. 8. A stock for a firearm, comprising: a proximal end shaped to allow a user to brace the stock;a distal end shaped to interface with the firearm;a longitudinal axis fixed by a firing direction of the stock and extending between the proximal end and the distal end;a housing including a mounting space along the longitudinal axis, the mounting space shaped to slidingly engage a receiving component of the firearm; anda length of pull adjustment mechanism movable between an engaged configuration and a disengaged configuration, wherein the length of pull adjustment mechanism comprises: a first lever having a receiving component contact surface;a second lever coupled to the first lever and having a receiving component contact surface; andthe first lever and the second lever are pivotally coupled to the housing and adapted to pivot about a pivot axis as the length of pull mechanism is moved between the engaged configuration wherein the first and second levers contact a receiving component of the firearm and the disengaged configuration wherein the first and second levers do not contact the receiving component; andthe first and second levers are adapted to engage the receiving component of the firearm having the firearm stock, the receiving component of the firearm manufactured within a minimum tolerance stack-up and a maximum tolerance stack-up; and whereina distal end of the first lever is configured to abut the receiving component when the length of pull adjustment mechanism is in the engaged configuration and the receiving component has the minimum tolerance stack-up; andthe distal end of the first lever is configured to disengage from the firearm when the length of pull adjustment mechanism is in the disengaged configuration and the receiving component has the maximum tolerance stack-up. 9. The stock of claim 8, wherein: distal ends of the first and second levers are positioned in an interior space of the housing and proximal ends of the first and second levers are positioned exterior of the housing. 10. The stock of claim 8, wherein: the length of pull adjustment mechanism is biased towards the engaged configuration. 11. The stock of claim 8, wherein: the length of pull adjustment mechanism has a locating member translatably coupled to the housing; andas the length of pull adjustment mechanism is moved from the disengaged configuration to the engaged configuration, a distal end of the first lever and the distal end of the second lever are shaped to bottom out against the receiving component before the locating member bottoms out against the firearm.
