I pulled back the slide hammer and let it slingshot and 3 rounds full auto fired and it was on safety. I did not have my finger on the trigger. Anywho, from what i was told it is a semi? Is there a way to find out if its a full auto or a semi that was modified? The other side of the.

Introduction
The purpose of this manual Is to provide the necessary instructions and manufacturing data required for conversion of the Ruger 10-22, semi-automatic carbine, into a selective fire automatic unit.
When modified to the specifications given, the weapon retains its semi-automatic mode of operation and also allows fully automatic functioning by moving the selector lever into the proper position.
The Ruger 10-22 made its debut in 1964, and has become one of the most popular firearms of its type in the world.
These weapons are logical choices for automatic conversion because they have proven themselves to be well made, very rugged, maintain a relatively light weight, and are adaptable to many different sighting arrangements.
The Ruger 10-22 Is an economical weapon to purchase, thereby increasing Its availability to many persons hampered by the struggling economy. New prices for the standard carbine run 1n the S90.00 to $110.00 range. Good condition used carbines can be purchased for approximately $45.00 to $75.00.
Another distinct advantage of the system is that ammunition expenses are held to a minimum when compared to various centerfire systems.
The .22 L.R. cartridge is limited in its power and range, but in the fully automatic mode, the 10-22 is a formidable weapon for many applications.
The weapon is well adaptable to silencer construction and use. Many various stock configurations are available, providing greater flexibility for intended use.
Numerous high capacity magazines are available for use with the Ruger 10-22. Gow mac 590 manual pdf. The EATON SUPPLY, INC. 25 rd., CONDOR 25 rd., HITCHELL 50 rd., and THOMPSON style 50 rd., drum magazines provide much greater flexibility over the standard 10 rd. magazine.
Sequence Of Operation
A look through the accompanying drawings will give the exact orientation and relationship of the parts controlling the firing cycle.
To achieve positive and reliable functioning, the trigger group for the select-fire Ruger 10-22 was redesigned Incorporating the basic design of the Belgian FN-FAL and West German HK-G3 battle rifle families. Both of these weapon systems are legendary in performance and reliability.
The modified 10-22 still retains the closed-bolt mode of operation.
When firing the modified weapon, the following sequence of events occur:
(1) COCKING THE WEAPON
1. Assuming there is a loaded magazine in place, the user retracts the bolt handle (and bolt assembly) which rotates the hammer rearward. This action compresses the recoil spring.
2. As the hammer almost completes Its rearward rotation, the bottom of the hammer contacts the top of the disconnector which 1n turn pivots downward, releasing the sear to rotate upward into position against the hammer. Mac 2816 repair manual. The engagement between the hammer and sear is not yet set at this time because the hamner is fully rotated rearward.
3. During this same initial rearward movement of the bolt and hammer, the release lever and catch also move rearward slightly. The travel of these parts 1s limited by the ejector pin which is positioned through a slot In the release lever. Both parts have independent torsion springs which forces them to rotate rearward. The stationary arm of these springs locates against the ejector pin. As the bolt and hammer complete their rearward travel, the engagement surface of the catch is against the hainner ready to engage the 'burst' notch. Mcculloch mini mac 6 manual.
4. When the bolt is fully retracted, 1t Is released. Recoil spring tension then propels it forward.
5. At this same instant, the hammer (released from contact with the bottom of the bolt) rotates forward slightly and securely engages the sear and catch, (both previously positioned) in their respective engagement notches.
6. As the bolt is moving forward, 1t strips a live cartridge from the magazine and begins to chamber ft.
7. At a given point just before the bolt closes completely, the top of the release lever (having previously moved rearward) makes contact with a radiused slot machined in the bottom of the bolt. As the bolt continues forward motion, the release lever rotates forward. Through engagement with the catch by means of a laterally positioned roll pin, the release lever rotates the catch out of engagement with the hammer. (Both the catch and release lever pivot on a coomon pin).
At this point, the weapon is ready to fire.
(2) SEMI-AUTO FIRE
1. The weapon is now in a loaded and cocked position as established in the sequence above.
2. The safety should now be moved to the 'OFF' position. (The safety is unaltered in this modification and functions identically as before. By moving the safety to 'OFF,' the lower lug of the sear is provided with clearance to enable downward travel when the trigger is depressed).
3. The selector lever roust be positioned in the rearward, or 'semi' position. In this position a lug on the bottom of the selector lever pivot will be positioned in a downward position and will limit the upward travel of the rear section of the trigger.

4. Depress the trigger, thereby releasing the sear and hammer engagement. The hammer, under spring tension from the hammer spring, rotates forward striking the rear of the firing pin and detonating the cartridge.
5. The bolt, acting on the pressure generated during the resultant explosion of detonation, moves rearward, extracting and ejecting the fired cartridge case.
6. As the bolt moves rearward, the release lever moves as previously explained. As the bolt completes rearward travel, the disconnector disengages the sear enabling it to be in position for re-engagement with the hammer (as previously described).
7. Forward bolt travel performs the same functions as previously described. For another shot to be fired, the user must release the trigger and then depress it again to resume the sequence as described.
1. The weapon 1s in a loaded and cocked position (as described in #1-7).
2. The safety 1s moved 'OFF' (as described 1n #2-2).
3. The selector lever must be positioned in the forward or 'BURST' position. In this position, the lug on the bottom of the selector lever pivot has rotated rearward enough to avoid contacting the upper, rear area of the trigger. The trigger in this position can be depressed further.
4. Fully depress the trigger, thereby releasing the hammer-sear engagement and resulting in detonation of the cartridge (as described 1n #2-4).
5. The trigger remains depressed as the bolt cycles rearward, extracting and ejecting the fired case (as described in #2-5).
6. The release lever and catch have rotated rearward (as described in sfl-3).
7. At the rearmost travel of the bolt and hammer, the disconnector pivots downward and releases the sear to pivot upward. However, because the trigger/sear assembly has rotated further down than 1t did in the 'semi' mode, the sear 1s not high enough to engage the hammer. The catch securely engages the hammer 'burst notch,' thereby holding the hammer rearward as the bolt begins forward travel, stripping and chambering a live cartridge.
8. At the Instant before the bolt closes completely, the release lever contacts the bolt, pivots forward and disengages the catch (as described in #1-7). This allows the hammer to strike the firing p1n and detonate the cartridge.
This cycle is repeated until the trigger is released. The sear can then rise, intercept the hammer* and interrupt the firing cycle.
SEMI-AUTO FUNCTIONING

FULL-AUTO FUNCTIONING
Selector is set at 'BURST'. Safety 'OFF'.
Weapon has fired and bolt is moving forward under recoil spring tension.
Trigger is fully depressed, lowering the sear nose low enough to not engage hammer. Release lever and catch have moved rearward and catch is engaging burst notch.
When bolt contacts and trips the release lever and catch assembly, the hammer falls to detonate cartridge.
