Editing Bolt action (section)

=== Bolt knob ===
The bolt knob is the part of the bolt handle that the user grips when loading and reloading the firearm and thereby acts as a [[cocking handle]]. On many older firearms, the bolt knob is welded to the bolt handle, and as such becoming an integral part of the bolt handle itself. On many newer firearms, the bolt knob is instead threaded onto the handle, allowing the user to change the original bolt knob for an aftermarket one, either for aesthetical reasons, achieving better grip or similar.<ref name="Shooting Illustrated 2012">{{cite web | title=Get a Handle on It | website=Shooting Illustrated | date=17 August 2012 | url=https://www.shootingillustrated.com/articles/2012/8/17/get-a-handle-on-it/ | access-date=12 April 2021}}</ref> The type of threads used vary between firearms. European firearms often use either M6 1 or M8 1.25 threads, for example M6 is used on the [[SIG Sauer 200 STR]], [[Blaser R93]], [[Blaser R8]], CZ&nbsp;457<ref name="area419"/> and Bergara rifles,<ref name="area419">{{cite web | title=419 Bolt Knobs – Area 419 | website=Area 419 – Precision Comes Standard | date=29 September 2016 | url=https://www.area419.com/product/419-bolt-knob/ | access-date=12 April 2021}}</ref> while M8 is used on the [[Sako TRG]] and [[SIG Sauer 404]]. Many American firearms instead use 1/4" 28&nbsp;TPI (6.35 0.907&nbsp;mm) or 5/16" 24&nbsp;TPI (7.9375 1.058&nbsp;mm) threads. Some other thread types are also used, for example, No. 10 32&nbsp;TPI (4.826 0.794&nbsp;mm) as used by Mausingfield.<ref name="area419"/> There also exists aftermarket slip-on bolt handle covers which are mounted without having to remove the existing bolt handle.<ref name="Pandemic 2016">{{cite web | last=Pandemic | first=Major | title=Review: KRG Remington Action Bolt Lift Oversized Bolt Handle Knob | website=AllOutdoor.com | date=18 October 2016 | url=https://www.alloutdoor.com/2016/10/18/review-krg-remington-action-bolt-lift-oversized-bolt-handle-knob/ | access-date=12 April 2021}}</ref> These are often made of either rubber or plastic.
