Savage Bolt Lift Kit (2019+ rifles)

Savage Bolt Lift Kit for newer production Savage models 10, 110, 11, 111, 12, 14, 114, 16, 116 and others.

The Lumley 4-piece Bolt Lift Kit for the 2019+ Savage rifles is designed as a direct replacement for the factory 3-piece striker spring assembly. Lumley also produces a lightweight titanium BAS for 2019+ rifles here. Many of the newer production rifles from 2019 and onwards have the striker spring assembly contained entirely between the BAS and cocking piece pin. This results in a much stiffer spring rate compared to the older adjustable design due to the short overall spring length required, which in turn creates a heavier bolt lift. This 2019+ Savage design consists of two main springs with a wire ring in-between to account for the radial movement required for opening (cocking) the bolt assembly. The Lumley solution operates within these design parameters but offers the following benefits:

• Instead of 1 spring isolator made from wire, Lumley includes 2 spring isolators which significantly reduces the friction coefficient
• These spring isolators are made from acetal bar stock containing 20% PTFE fibers which results in less galling and a much smoother bolt lift
• Included are two different weights for mainspring #1 which enables you to tailor the ideal spring weight required to detonate the primers used in your preferred ammunition
• The striker springs are coiled from high-quality music wire which offers very good fatigue resistance
• Also included are multiple spares of mainspring #1 for when they require replacing after exceeding their elastic limit when cocked

Included:

• 3x 'standard' striker mainspring #1 (gold color)
• 3x '10% lower power' striker mainspring #1 (silver color)
• 1x striker mainspring #2
• 2x Delrin 500 spring isolators

Construction:

• The striker springs are coiled from a high-quality music wire steel and then zinc-plated
• The spring isolators are CNC turned from DELRIN® 500AF barstock (acetal with 20% PTFE fibers)

Fitting: 

This is a relatively straightforward part to fit. Lumley recommends clamping the bolt in a bench vise (using either soft-jaws or an aluminum v-block) with the BAS facing upwards, de-cocking the striker pin, and then unscrewing the BAS, which on most 2019+ models will be by using a 1/4" hex key. Take care with this last step as the BAS will still be under spring pressure. Included in the image gallery (above) is a series of exploded diagrams of the 2019+ Savage bolt assembly showing all these components and how they fit together. Reassembly is done by replacing the old 3-piece components with the Lumley 4-piece kit and following the above steps in reverse. Lumley recommends re-cocking the striker pin by removing the assembled bolt from the vise and holding the cocking piece pin against the top edge of the vice and firmly pulling the bolt downwards and twisting until the cocking piece pin cams into location.

Prolonging the life of the mainsprings

Lumley has measured the whole striker spring assembly on the 2019+ Savage rifles as just shy of 3/4" (19mm) when the bolt is cocked. It is recommended when not in use, the bolt should be kept un-cocked, either by inserting it into the receiver and dry firing (after first checking that the rifle is unloaded) or by using a bolt protector that de-cocks the bolt when stored. This will minimize the stress placed on the striker mainsprings and prolong their lifetime.
