Greetings Me Droogs and Droogettes!
The M203 is a rifled, single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle.
Now, the 203, on it’s own, off-rail so to speak, looks like this:
It’s a single shot, breech load that opens like a pump-shotgun.
As seen here with a blue-tipped training round, you can see how the round is ‘fed’ into it. It’s been in service since 1969, originally with the SF Kids who wanted a 40mm weapon that was mounted ON the M-16 as opposed to the separate weapons system, the M-79 “Bloop” Gun, which was a standalone 40 mike mike that looked like a retarded single shot shotgun.
Its designed to break through windows and exploding inside where bad guys might be.
This’s it in standalone mode. It’s got a pistol grip, features a spring loaded side load, and is double action on the trigger as opposed to single action on the 203. It comes issued with the retractable stock, and a digital rangefinder which helps to figger out if the target is in range. Lase and Blaze apparently.
OK, now, to be honest, the guys I talked to who I issued these to (yeah, I was on the initial fielding for them back when I was doing the Depot Level Small Arms Repair thing) had a love/hate thing going on. For one major issue was the bulkiness of the fucker when it’s underbarrel. Purely loved it in self-standing mode tho… more accurate, and the load/unload of the round meant a far faster increase in round output downrange.
Now, unlike the 203, the 320 when you hit the ‘eject’ button, the 320 literally springs open and spits out the spent shell. Like violently. Compare this to the 203, where you push the release, slide the barrel forward, and IF you don’t have a shitty extractor, the empty casing falls out.
Good for about 200-250 meters.
as you can see, it’s got two flip out sight posts, and the thing slides up n’ down for aiming. Set the slide to whatever estimated range the target is at, aim thru the peepsites, and >BLOOP!<
2. (M406) High-Explosive Round. The HE round has an olive drab aluminum skirt with a steel projectile attached, gold markings, and a yellow ogive. It arms between 14 and 27 meters, produces a ground burst that causes casualties within a 130-meter radius, and has a kill radius of 5 meters.
3. (M583A1) Star Parachute Round. This round is white impact or bar alloy aluminum, with black markings. It is used for illumination and signals and is lighter and more accurate than comparable handheld signal rounds. The parachute attached to the round deploys upon ejection to lower the candle at 7 feet per second. The candle burns for about 40 seconds. A raised letter on the top of the round denotes the color of the parachute.
4. (M585) White Star Cluster Round. This round is white impact or bar aluminum alloy, with black markings. The attached plastic ogive has five raised dots for night identification. The round is used for illumination or signals. It is lighter and more accurate than comparable handheld signal rounds. The individual stars burn for about 7 seconds during free fall.
5. (M713) Ground Marker Round. This round is light green impact aluminum with black markings. It is used for aerial identification and for marking the location of soldiers on the ground. It arms between 15 and 45 meters. If a fuse fails to function on impact, the output mixture provided in the front end of the delay casing backs up the impact feature. The color of the ogive indicates the color of the smoke.
6. (M781) Practice Round. Used for practice, this round is blue zinc or aluminum, with white markings. It produces a yellow or orange signature on impact, arms between 14 and 27 meters, and has a danger radius of 20 meters.
7. (M651) CS Round. This round is gray aluminum with a green casing and black markings. Though it is a multipurpose round, it is most effective for riot control and in Urban Operations. It arms between 10 and 30 meters and produces a white cloud of CS gas on impact.
8. (M576) Buckshot Round. This round is olive drab with black markings. Though it is a multipurpose round, it is most effective in thick vegetated areas or for room clearing. Inside, it has 20 metal pellets, each weighing 24 grains, with a muzzle velocity of 269 meters per second. The round has no mechanical-type fuse.
My personal fave is the M576… Big assed super-buckshot round… good in-close weapon on hordes-o’-hajjis.
