CST Auto Bolt Stop
|
The CST Automatic Bolt Stop is designed to automatically
stop the forward travel of the bolt upon its full retraction if and when
there is an absence of a cartridge in the magazine or an absence of a
magazine all together. Upon the discharge and ejection of the last round
loaded in the rifle, the auto-bolt stop mechanism will detect the
absence of a fresh cartridge and automatically stop the bolt’s forward
travel upon an empty chamber. To load the rifle with the bolt locked
open, insert the supplied CST modified magazine with one or more
cartridges loaded and then pull rearward the bolt and let go. The
cartridge present in the magazine will trip the auto-bolt stop mechanism
and allow the bolt to carry the cartridge forward into the chamber.
The auto-bolt stop tab located next to the magazine latch is designed to manually release the bolt from a locked position. Manual bolt stop release is primarily needed to close the bolt on an empty chamber or can be used to clear a jam during a firing session. To use the manual release function you should pull back on the bolt to relieve tension on the bolt stop, and then push forward the auto-bolt stop tab, and while holding the tab forward, release the bolt. Releasing a locked bolt by simply pushing forward the auto-bolt stop tab requires some exertion and will prematurely wear out the locking surface of the bolt stop. This practice is not necessary or recommended.
To unload the rifle, remove the magazine and pull back the bolt until it is automatically stopped in a rearward position. This will clear most factory size chambers of a live round and lock the bolt open, exposing an empty chamber. Some tight chambered match barrels may not extract a live cartridge. The CST Automatic Bolt Stop is fully compatible with most aftermarket products for the Ruger 10/22* rifle, including magazine latches, triggers, sears, hammers, etc. HOWEVER, FOR THE AUTO-BOLT STOP MECHANISM TO FUNCTION CORRECTLY ONLY CST MODIFIED MAGAZINES CAN BE USED. |
