The objective of this manual is to provide the crucial instructions and also manufacturing data compelled for counter of the Ruger 10-22, semi-automatic carbine, right into a selective fire automatically unit.

When modified come the specifications given, the weapon retains its semi-automatic mode of procedure and additionally allows completely automatic work by relocating the selector lever into the ideal position.

The Ruger 10-22 make its debut in 1964, and has come to be one of the most well-known firearms the its kind in the world.

These weapons space logical choices for automatically conversion due to the fact that they have proven us to be fine made, really rugged, keep a fairly light weight, and are adaptable to many different sighting arrangements.

The Ruger 10-22 Is an economical weapon to purchase, thereby boosting Its access to plenty of persons hampered by the struggling economy. New prices for the conventional carbine operation 1n the S90.00 to $110.00 range. Great condition supplied carbines can be purchase for about $45.00 come $75.00.

Another distinct benefit of the system is the ammunition costs are organized to a minimum when contrasted to various centerfire systems.

The .22 L.R. Cartridge is limited in its power and also range, however in the fully automatic mode, the 10-22 is a formidable weapon for plenty of applications.

The weapon is fine adaptable to silencer construction and use. Plenty of various stock configurations space available, giving greater versatility for plan use.

Numerous high capacity magazines are easily accessible for use v the Ruger 10-22. The EATON SUPPLY, INC. 25 rd., CONDOR 25 rd., HITCHELL 50 rd., and THOMPSON layout 50 rd., north magazines provide much greater flexibility over the typical 10 rd. Magazine.

Sequence that Operation

A look with the accompanying drawings will give the exact orientation and also relationship that the parts controlling the firing cycle.

To accomplish positive and also reliable functioning, the trigger group because that the select-fire Ruger 10-22 was redesigned combine the straightforward design that the Belgian FN-FAL and also West German HK-G3 fight rifle families. Both of these weapon systems are legendary in performance and reliability.

The modified 10-22 still maintain the closed-bolt mode of operation.

When firing the modification weapon, the complying with sequence of events occur:


Assuming over there is a loaded magazine in place, the user retracts the bolt handle (and bolt assembly) i m sorry rotates the hammer rearward. This action compresses the recoil spring.As the hammer almost completes the rearward rotation, the bottom of the hammer contacts the optimal of the disconnector i m sorry 1n turn pivots downward, publication the sear to turn upward into position versus the hammer. The engagement between the hammer and also sear is not yet set at this time due to the fact that the hamner is completely rotated rearward.During this same initial rearward movement of the bolt and hammer, the release lever and also catch also move rearward slightly. The take trip of these parts 1s limited by the ejector pin which is positioned v a slot In the relax lever. Both parts have actually independent torsion springs which forces them to turn rearward. The stationary arm of this springs locates versus the ejector pin. As the bolt and also hammer complete their rearward travel, the engagement surface ar of the capture is against the hainner prepared to interact the "burst" notch.When the bolt is totally retracted, 1t Is released. Recoil spring stress and anxiety then propels that forward.At this very same instant, the hammer (released from contact with the bottom that the bolt) rotates front slightly and securely engages the sear and catch, (both formerly positioned) in their corresponding engagement notches.As the bolt is relocating forward, 1t strips a live cartridge indigenous the magazine and also begins to room ft.At a given suggest just prior to the bolt close the door completely, the peak of the release bar (having previously relocated rearward) makes contact with a radiused slot machined in the bottom the the bolt. Together the bolt continues forward motion, the release lever rotates forward. Through engagement with the catch by method of a laterally positioned roll pin, the release bar rotates the capture out the engagement v the hammer. (Both the catch and release bar pivot ~ above a coomon pin).

At this point, the weapon is all set to fire.


The weapon is currently in a loaded and also cocked place as established in the succession above.The safety should now be moved to the "OFF" position. (The security is unaltered in this change and functions identically together before. By moving the safety and security to "OFF," the lower lug that the sear is noted with clearance to permit downward travel when the trigger is depressed).The selector lever roust be positioned in the rearward, or "semi" position. In this position a lug top top the bottom that the selector bar pivot will be positioned in a bottom position and also will limit the upward travel of the rear section of the trigger.Depress the trigger, in order to releasing the sear and also hammer engagement. The hammer, under spring stress from the hammer spring, rotates forward striking the rear of the shoot pin and detonating the cartridge.The bolt, acting on the push generated during the result explosion that detonation, move rearward, extracting and also ejecting the fired cartridge case.As the bolt move rearward, the release lever moves as previously explained. Together the bolt completes rearward travel, the disconnector disengages the sear allowing it to be in place for re-engagement through the hammer (as previously described).Forward bolt travel performs the same attributes as formerly described. For another shot to be fired, the user have to release the trigger and also then boring it again to resume the sequence together described.


The weapon is in a loaded and cocked positionThe security is moved "OFF"The selector bar must it is in positioned in the forward or "BURST" position. In this position, the lug ~ above the bottom that the selector lever pivot has actually rotated rearward enough to stop contacting the upper, rear area of the trigger. The cause in this position deserve to be depression further.Fully depress the trigger, thereby releasing the hammer-sear engagement and also resulting in detonation of the cartridge.The cause remains depressed together the bolt cycles rearward, extracting and ejecting the fired caseThe relax lever and catch have rotated rearwardAt the rearmost travel of the bolt and hammer, the disconnector pivots downward and also releases the sear to pivot upward. However, since the trigger/sear assembly has actually rotated further down than 1t go in the "semi" mode, the sear 1s not high sufficient to communicate the hammer. The catch securely engages the hammer "burst notch," thereby holding the hammer rearward together the bolt begins forward travel, stripping and chambering a live cartridge.At the Instant before the bolt close the door completely, the release lever contacts the bolt, pivots forward and disengages the record This permits the hammer to strike the shoot p1n and detonate the cartridge.This bicycle is recurring until the trigger is released. The sear deserve to then rise, intercept the hammer* and also interrupt the shooting cycle.


Selector is collection at "SEMI".Bolt is in closed position.Hammer is cocked, sear engaged.Release lever and also catch have actually pivoted forward.Safety "ON".



Selector is set at "BURST". Security "OFF".Weapon has fired and bolt is moving forward under recoil feather tension.Trigger is completely depressed, lowering the sear nose low sufficient to not connect hammer. Relax lever and catch have moved rearward and catch is engaging burst notch.

When bolt contacts and trips the relax lever and catch assembly, the hammer drops to detonate cartridge.
