Model-specific safety

The stock pin is NOT captive once removed. Kel-Tec puts that in capitals. Lose it and the carbine does not go back together.
The buffer assembly is under recoil spring tension the whole time the stock pin is out. Keep positive contact with it or parts will fly loose. Wear eye protection.
Do not release the hammer with the bolt assembly removed. Kel-Tec states this will make the rifle inoperable.
Do not release the bolt from its locked-back notch while the barrel is folded into storage mode; it can damage the receiver tube.
The latching tab that holds the barrel folded is a transport detent, not a lock or a safety. Kel-Tec says so explicitly.
The barrel latch is released by rotating the trigger guard down, away from the trigger — the same place your finger goes. Be deliberate about which you are doing.
Kel-Tec strongly discourages unscrewing the collar or barrel: they are assembled with special tools and compounds and can be damaged by improper removal.

If it will not go back together

Common ways this firearm resists reassembly, and what is actually wrong. Forcing a part that will not seat is how firearms get damaged.

The stock pin will not go back in.

Why The slot in the buffer assembly, the chosen stock position and the receiver are not all aligned at once.

Fix Press the buffer assembly forward against spring tension, line up the buffer slot with the stock position hole and the receiver, then push the pin through. Kel-Tec notes this takes some adjusting of the parts.

Forcing it Driving the pin against misaligned holes burrs the pin and the stock.
The stock pin is lost.

Why It is not captive once removed, which Kel-Tec warns about in capitals.

Fix It is a service part from Kel-Tec. Do not substitute a pin of approximate diameter — it carries the buffer and recoil spring load.

Gunsmith Do not attempt this one yourself.
The operating handle will not go back in.

Why The hole in the bolt is not lined up with the operating handle slot in the receiver.

Fix Slide the bolt until the handle hole sits over the slot, then insert the handle fully before fitting the recoil spring.
The rifle is assembled but will not function, and the hammer was dropped during cleaning.

Why The hammer was released with the bolt assembly out.

Fix Kel-Tec states this makes the rifle inoperable and it is not something to correct by feel. Have it looked at rather than forcing the action.

Gunsmith Do not attempt this one yourself.
Parts flew loose while removing the stock pin.

Why Positive contact with the buffer assembly was lost while it was under recoil spring tension.

Fix Recover the buffer assembly, recoil spring and stock pin, and restart the strip keeping a hand on the buffer throughout.

Forcing it This is the step on this carbine where eye protection matters.

Shop difficulty

Shop tier 2 Tier 2 — moderate among rifles and carbines, for the full job: strip to the parts that get coated and put it back together working. 76 line items (112 pieces) in a clamshell polymer grip/frame held by pins, with a buffer and stock pin under recoil-spring tension. Kel-Tec warns that dropping the hammer with the bolt out makes the rifle inoperable. The stock pin needs the buffer, stock position and receiver lined up at once. There are many parts and several traps, but no timing.

Parts: 76 numbered parts (SUB2000 exploded view and parts list (REV 013020), 9mm and .40 rows), from Kel-Tec SUB2000 / SUB CQB Owner's Manual — Kel-Tec CNC Industries, Inc., p. 26–27 media.keltecweapons.com [1].

Bench time: about 45 min to strip, 75 min to rebuild (estimate). Estimate: field strip (stock pin, buffer, recoil spring, bolt, operating handle), split the grip/frame halves (receiver grip pins), trigger group (hammer, trigger, sear, safety, springs), trigger guard latch, mag catch, sights. Rebuild longer: clamshell alignment with the trigger parts in place, stock pin alignment.

Small parts: 12 pins, 14 springs, 4 detents or plungers (counted from the manufacturer's parts list (one per key number unless a quantity is given))

What comes off for coating

Receiver tube: stock pin, buffer assembly, recoil spring, bolt assembly (firing pin and spring, extractor and spring), operating handle, front sight and detent pin/spring, rear sight/windage detent and spring
Grip / trigger housing (clamshell): receiver grip pins (long, short), hammer and hammer spring, trigger, trigger bar pin, trigger spring, sear and spring, safety, pin and spring, trigger guard, latch and springs, mag catch and spring — pin punches

Special tools

Pin punches — Receiver grip pins, trigger bar pin
Front sight tool/screwdriver — Front sight detent

Procedures

Clear and Make Safe

Clear & Make Safe

Clear it before you fold it. A folded carbine cannot be inspected.

Point the muzzle in a safe direction and keep your finger off the trigger.
Place the weapon in the SAFE configuration using the push-bolt safety behind the trigger.
Remove the magazine.
Cycle the bolt assembly manually to eject any chambered cartridge.
Inspect the chamber and magazine well with a light and physically confirm the chamber is empty.
Confirm the carbine is unfolded, with the barrel assembly rotated to the chambering position, while you clear it.
Remove all live ammunition from the work area.

Folding and Unfolding (Storage Mode)

Field Strip

Manufacturer’s video: Kel-Tec SUB-2000 Field Strip KelTec

Ensure the weapon is unloaded, with no magazine or ammunition present, and place it in the SAFE configuration.
Remove any accessories on the top rail of the forend that would interfere when folded.
Rotate the trigger guard down, away from the trigger. The barrel assembly is then free to rotate around the rear sight axis.
WarningYour trigger finger and this latch occupy the same space. Move the guard deliberately.
Rotate the barrel assembly until it latches into the latching tab in the buffer assembly.
WarningThe latching tab assists the barrel in staying closed for transport. It is not a lock or a safety.
To open from storage mode, press the latching tab rearward, away from the grip, to release the barrel assembly, then rotate it to the chambering position.
WarningDo not release the bolt assembly from its notched, locked-back position while the barrel is folded. Doing so could damage the receiver tube.

Field Strip

Field Strip tools required

Manufacturer’s video: Kel-Tec SUB-2000 Field Strip KelTec

Rotate the barrel assembly into the forward position if it was folded, and complete the Clear and Make Safe procedure.
Make sure the bolt assembly is forward (closed), the hammer is cocked and the push-bolt safety is engaged.
Press the buffer assembly in, towards the front of the weapon. It will move about 3/32 inch before bottoming out on the stock pin.
Release a small amount of tension on the buffer assembly so the stock pin can begin to come out.
TipThe stock pin is held captive by the buffer assembly. Easing off slightly is what frees it.
With a cartridge or other pointed object, press the stock pin out from either side.
WarningKeep positive contact with the buffer assembly while the pin comes out — it is under recoil spring tension and parts may fly loose. The pin is not captive once removed. Put it somewhere safe immediately.
Removed at this step: Stock pin
Remove the buffer assembly and set it aside.
Removed at this step: Buffer assembly
Pull the bolt assembly back by the operating handle and pull out the recoil spring.
Removed at this step: Recoil spring
Pull the operating handle out downwards.
TipDownwards, not rearward.
Removed at this step: Operating handle
Slide the bolt assembly out of the rear of the receiver tube, and separate it by lifting the bolt head off the bolt.
Removed at this step: Bolt Bolt head
The stock can be removed or its position adjusted now that the stock pin is out. The barrel assembly can be rotated up for cleaning or inspection.
Stop here.
WarningDo not release the hammer with the bolt assembly removed — Kel-Tec states this will make the rifle inoperable. Further field stripping is not required for normal operation.

Reassembly

Manufacturer’s videos: SUB-2000 Assembly KelTec · KelTec SUB-2000 Hammer Reset KelTec

Assemble the bolt head onto the bolt.
Insert the combined bolt and bolt head into the receiver.
Line up the operating handle hole with the operating handle slot below, and fully insert the operating handle.
Put the recoil spring into the bolt, then slide the bolt assembly forward.
Add the stock to the receiver and set the stock position.
TipPosition 1 is the shortest overall length; position 2 adds 5/8 inch; position 3 adds 1.25 inches.
Add the buffer assembly, pressing the bolt assembly slightly rearward if needed so the recoil spring and buffer assembly line up.
WarningThe buffer assembly is under recoil spring tension.
Press the buffer assembly towards the front of the weapon and line up the slot in the buffer assembly with the desired stock position and the receiver.
Push the stock pin completely in.
WarningThis may take some adjusting of the parts to get complete alignment. Do not drive it against misaligned holes.
Release the tension on the buffer assembly and cycle the bolt assembly a few times to check the action.

Torque specifications

Use a calibrated torque driverValues are the manufacturer's, shown in the unit it gives first; conversions are calculated and rounded. Tighten to the stated value — not "until it feels right" — and follow any sequence noted.

Notes: From Kel-Tec's SUB2000 / SUB CQB owner's manual (GEN2). Kel-Tec states the barrel maximum twice — as a number and as a warning — because tightening a muzzle accessory past it can damage the rifle.

Materials and factory finish

As stated by Kel-Tec CNC Industries. Prep, masking and cure depend on these; a polymer or aluminium part, a nitrided or anodised finish, and a blued steel part are each a different job. Variants with other finishes may exist — check the maker's page for the exact SKU on the bench.

Function check

After every reassemblyPerform these checks on a verified-unloaded firearm. If any check fails, the firearm is not safe to fire — stop and see a licensed gunsmith.

Verify the firearm is unloaded with no magazine inserted before each step.
Cycle the action by hand and confirm the bolt returns fully into battery.
With the safety on, press the trigger. The hammer or striker must not release.
Move the safety to fire, cycle the action, and press the trigger. It should release.
Hold the trigger back, cycle the action, and release slowly to feel the disconnector reset.
Confirm the magazine seats and locks positively and releases cleanly.
Confirm the carbine is fully unfolded and the barrel latch is engaged.
Attempt to fold it without releasing the latch — it must not move.

Maintenance

Lubrication points

Bolt body where it rides in the receiver
Recoil spring and guide
Hammer and sear pivots

Cleaning notes

Pistol-caliber blowback actions foul heavily and quickly — far more than a locked-breech rifle, because the case begins moving while pressure is still high. Clean the bolt face and receiver interior regularly and keep lubrication moderate.

Suggested inspection interval: roughly every 1000 rounds. This is a general guideline, not a manufacturer specification.

Wear parts to inspect

Recoil spring · Extractor and spring · Bolt face · Magazine springs and feed lips

Common issues

Symptom	Likely cause	What to do
Carbine will not fold	Barrel latch not released	Pull down on the trigger guard to release it. Confirm the chamber is empty first.
Accuracy shifts between folding cycles	Barrel latch wear or an optic mounted on the barrel rather than the receiver	Mount optics on the receiver. Have a worn latch inspected. see a gunsmith

Legal notes

Not legal adviceOverall length and barrel length determine legal classification. A folding carbine’s folded length is generally not what governs its classification — verify the law where you are before assuming.

Notes: Verified against Kel-Tec's SUB2000 / SUB CQB owner's manual (34 pages), sections C "Storage Mode" (pp. 7-8), D "Field Strip" (pp. 15-17) and E "Assembly from Field Strip" (pp. 19-21). The previous entry was rated low and unverified, and its field strip said only to "remove the buttstock assembly retaining components" — which skipped the entire procedure. The carbine comes apart at a stock pin held captive by a spring-loaded buffer assembly: the buffer is pressed forward about 3/32 inch, eased back slightly, and the pin pushed out with a cartridge while keeping positive contact. Kel-Tec warns in capitals that the pin is not captive once out. Two hazards the old entry did not carry: releasing the hammer with the bolt removed makes the rifle inoperable, and releasing the bolt from its locked-back notch while folded can damage the receiver tube. This manual covers the GEN2 and the SUB CQB; Kel-Tec publishes separate manuals for the GEN1 and GEN3, and the suppressed-barrel section applies to the CQB only and is not reproduced here.
