Ruger Mini Carbine

The .223 (5.56 mm) Mini-14 resembles ihe U.S. M 14 ritle in appearance and incorporates the Garand rotating bolt principle.

Ihe Ruger-designed gun was first produced in 1974 in Southport. Conn., where about 1000 were made before production was transferred to the larger Sturm. Ruger plant in Newport, N.H. All Southport guns and early runs of those made at Newport bear serial numbers with the 180-prcfix. The Southport model can be identified by the sporting type, gold bead front sight.

In mid-1978, a refined Mini-14 replaced the "I80-" prefix models. Current production Mini-14 carbines bear the serial number prefix "I8I-". The drawings and information which follow apply only to the "I8I-" Mini-14 series.

Although several specialized variations of the Mini-14 designed for use by law enforcement and government agencies will be encountered from time to time, these are virtually identical to the standard production guns with respect to disassembles procedures. Government service Mini-14 carbines are usually equipped with a flash hider and with a special front sight with protective steel "ears" on either side of the sight blade. Some service models use a heat resistant ventilated upper handguard which replaces the standard wooden handguard.

Several different magazines are offered for this rifle. The most frequently encountered is the five-shot, but 10- and 20-shot magazines are also common. It is of interest that some "counterfeit" 30-shot magazines bearing false Ruger markings, but not made by Sturm, Ruger and Co.. have turned up.

The Mini-14 is a strong and reliable rifle designed for ease ol cleaning and maintenance. Only the simplest tools are required to field strip the arm for cleaning and lubrication. When field stripped, the component parts are large and not readily susceptible to loss.

Disassembly

1. Push magazine latch (35) forward and. with a forward/down movement, remove the magazine. Pull slide (59) fully to rear. Check chamber to be sure carbine is unloaded and release the slide which will ride forward under spring pressure. Place safety (54) in rearorMon" position (toward trigger). Note: Safety must be engaged and hammer cocked for disassembly or reassembly.

2. Holding the gun upside down, insert a small screwdriver or punch in the rear hole in the trigger guard

(68) and. exerting forward pressure, unlatch the trigger guard, freeing its rear tab from the trigger housing

3. Pull the entire trigger guard/ trigger group straight upward to remove. See Fig. B.

4. Holding the carbine with sights up. raise the rear of the receiver until it is just clear of the stock. Separate barreled action from stock (62). See Fig. C.

5. Grasp guide rod (22) and recoil spring (53) and pull toward muzzle until guide rod is free from its retaining recess in the front of the receiver. (Caution: Spring is under compression) Lift guide rod/recoil

• spring asembly clear of the receiver and withdraw the spring from the slide tunnel. See Fig. D.

6. Pull slide (59) to the rear until retaining projections are aligned with corresponding notches in the receiver. Remove slide as in Fig. E.

7. Move bolt (2) forward and pivot it upward. The firing pin (15) must be fully retracted for removal or replacement of bolt in receiver. Align tail of firing pin with slot in the interior of the receiver crossbridge. Remove bolt. See Fig. F. Note: Force should not be used or required to remove or replace bolt.

Further disassembly is not recommended by the factory and is not required for cleaning/maintenance. Reassembly is accomplished by reversing the above procedures.

In early 1979. Ruger announced a new version of the Mini-14 Carbine which is just now beginning to be delivered. It is in all respects identical to the 181-Series carbines except for the use of stainless steel which offers greater weather resistance and dramatically alters its appearance.

Ruger Illustration
Ruger Model 10/22 Carbine

By JAMES M. TRIGGS

The Ruger Model 10/22 carbine, introduced in 1964, is chambered for the .22 long rifle cartridge, regular or high velocity. This semi-automatic blow-back-operated arm has a detachable 10-shot rotary box magazine.

Receiver and trigger guard of the Model 10/22 are machined from lightweight alloy. An unusual V-block arrangement secures the 1814" barrel to the receiver. Removal of the barrel from the receiver during routine maintenance is not recommended.

The magazine should be disassembled occasionally for cleaning. Carefully re-tension the magazine spring according to the manufacturer's instructions.

Open sights are standard on the Model 10/22 carbine. However, the receiver is drilled and tapped for top telescope mounts.

Disassembly Procedure

Press up on magazine latch (6. Trigger Guard Assembly) and pull magazine (15) out from bottom of stock. Pull bolt handle (14) back and check action to be sure carbine is unloaded. Loosen barrel band screw (6) and slide barrel band (5) forward off stock. Unscrew takedown screw (12). Move safety (8. Trigger Guard Assembly) to centered position and lift barrel and assembly up out of stock from top. Drift out receiver cross pins (9) to left and drop trigger guard assembly (16) out bottom of receiver (1). Drift out bolt stop pin (10). Pull bolt assembly (13) to rear and lift out through bottom of receiver. Remove bolt handle (14) with recoil spring and guide assembly through side of receiver. Note: Bolt handle, recoil spring, guide rod. and bushing are a factory-staked assembly and further disassembly is not recommended. This completes disassembly for normal cleaning purposes.

To remove barrel, unscrew barrel retainer screws (8) and pull barrel (2) with barrel retainer (7) out of receiver ( 1 ) to front. Disassembly of lock mechanism contained in trigger guard assembly (16) should only be undertaken by a competent gunsmith for repair or replacement of parts (See Trigger Guard Assembly). Reassemble in reverse order.

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
