CAUTION: REPEATED DRY FIRING OF THE Mk19 WILL CAUSE UNNECESSARY WEAR TO THE BOLT. F. Place the safe-fire switch to show “F,” confirming that the weapon is ready to fire. G. Ease the bolt forward. 1. Hold one charging handle FIRMLY to the rear. 2. Press the trigger to release the bolt and ease the bolt forward under firm control. Don’t let it slam forward. 3. Ensure that both charging handles are in the forward and up position. H. Place the safe-fire switch to show ‘S” (safe). I. Index the feed slide assembly to the left. J. Close the top cover and make sure that the latche engages. Analysis of firing. While firing blanks during training is the most common use of the AR-22, the most important and sensitive uses of the AR-22 are to conduct pre-deployment weapon testing, pre-operational check firing, or post maintenance confirmatory test firing when live ammunition or suitable ranges aren’t available. The AR-22 will power the Mk19 at the same cyclic rate as live ammunition. A burst of approximately 10 rounds is needed to evaluate performance of the Mk19. Evaluate the burst for: Rate of Fire… speed of operation. While it would be useful to have specialized timing devices to measure rate of fire, such devices are normally not available. It is normally sufficient to have an experienced gunner to evaluate the rate of fire. A slow rate of fire indicates binding, fouling, or other resistance in the system. Successful firing of all rounds... A Mk19 in proper condition will fire a string of rounds at normal rate of fire, with a uniform tempo, and without failure.
CHAPTER 3 Maintenance Instructions
Removing the AR-22 from the Mk19
A. Ensure the safe-fire switch shows “S”, confirming that the weapon is on safe.
B. Pinch the front retainers of the Mk19s feed chute and swing the front outward.
Remove the round discriminator (the red piece attached to the yoke with a cable
D. Unscrew the AR-22 barrel insert from the yoke.
CAUTION: The barrel insert may be hot!
E. Remove the red AR-22 yoke from the flash suppresser. Grasp the insert barrel at
each end and assure that the assembly did not come unscrewed during removal.
F. In cool weather, water from propellant gasses may condense on the insert or Mk19
barrel . Wipe them clean and dry, then oil them to prevent damage to either.
Cleaning.
A. Use a rag dampened in CLP or RBC to wipe the outside of each cartridge case.
B. Use a 7.62mm cleaning rod, patch holder, and patch to clean the chamber and barrel
of each adapter cartridge.
C. Preserve with a light coat of LAW or, if none is available, with CLP.
Replacement of links.
A. Use a small bolt cutter to cut the link at its narrowest point; the circular socket
opposite the swivel. Remove and discard.
B. Insert the small, rounded T end of a swivel into the narrow slot of a link. Slip the link
over the mouth of the adapter cartridge, with the small, bent tabs of the link forward.
C. Set the link carefully on the cartridge; it must be driven down without tipping or
jamming.
D. Use the link positioning tool to press the new link back until it passes the groove at
the middle of the adapter cartridge, then use the tool to push it back into the groove.
AR-22 Reliability. The Mk19 firing blanks by means of the AR-22 will suffer a higher
level of malfunctions – normally delinkage - than when firing live ammunition because:
Repeated use of the ammunition links wears the links out, and delinkage failures will
become more frequent. Correct by replacing the links regularly.
The weapon dynamics are somewhat different than when firing live ammunition. Most
importantly, the rearward movement of the bolt is not countered by the forward
movement of a projectile, so the weapon jumps differently, adding stress to the
ammunition belt. This can be countered by fully extending the legs of the tripod,
sandbagging the tripod, and keeping the weapon as low to the ground as possible.
Live ammunition is packaged with dunnage (foam spacers) that carefully guides the
ammunition belt as it feeds. The many cylindrical spacers in the ammunition can fall to
the ground. While this long-lived rubbish is acceptable on the battlefield, it is strongly
frowned upon in training areas. ArmaLite has therefore minimized the dunnage by
omitting the cylinders and accepting a small amount of increased belt stress.
Transportation.
A. Clean and dry the cartridges, tools, and the interior of the ammunition can. Place the cartridges and tools in the can. B. Screw the AR-22 barrel insert into the yoke. The yoke will protect the threads of the barrel. C. Secure the barrel insert and yoke in a suitable box for transport.
