In its quest to be more lethal than Americas adversaries, the Marine Corps is rolling out a new grenade launcher.
The M320A1 has a range of 150 meters on a single target, which might be a window, and a 350-meter maximum range on an area target, according to The Washington Times.
The new grenade launcher can be used by itself or mounted onto another weapon, such as the M27 rifle.

Surplus, they are only $249.99.
Another improvement over the M203 or M79.
APOCALYPSE NOW!

The Horror,,,
hahahahahahaha. Thread winner!
On a Reforger back in the 80's we had a Blazer go rolling down a huge hill sideways with a case of M203 grenades in the back. While the officers were measuring turds we just went and unloaded it - six rolls being nowhere near arming the damn things. Good times.
The Corps is actually ahead of the Army in finally adopting a replacement for the M16 that doesn’t have the stupid direct impingement/pistonless action. The Marines adopted the M27 as the new Infantry Automatic Rifle to replace the M249, and now they’re just rolling it out to everyone as replacements for the M16 in the regular infantry rifle and the DMR roles too. It is also replacing the M4A1 in Marine Corps service, being chosen to be the standard issue rifle for every 0311.

So, you just shoot a flat trajectory like a rife rather than volley it up and down?
Duh, not the 203 TM but the M79. The older grenade launcher, but the basic picture is still the same.
Too true - I had to help in the Armory quite often so I wasn't concerned. The butterbar we had just out of West Point didn't get the memo and provided laughter for weeks: "Set up a safety perimeter! Someone call in the Explosive Ordinance unit! Oh crap, is gasoline leaking?" Better safe than sorry actually wasn't wrong but it was hilarious.
It's real nice that they don't have to be attached to the rifle anymore, like the 203s. That really sucked.
I loved my M203. Gotta hustle and get your weapon out of a stack? Instantaneous. Gotta hump a pack? It tended lay flat and still so no bounce bruising. The added weight and large front grip improved my range score dramatically and going to grenade practice was too fun to get paid for. I sincerely hope the new system is an improvement and not a contractor enrichment thing. I'm still pissed about the Barretas.
In Texas, that’s a 22LR sized derringer.
Old wives tales.
The number of revolutions is moot, it is the centripetal force generated by the rotational velocity that arms the fuze- think spring loaded pins with a locking mechanism, once the round is spun so fast, the pins slide outwards, lock and the fuzes FP is then free to strike the detonator upon impact.
37 rotations is a fairy tale. However, it indeed takes about 25 m worth of time/rotation to retract the safety pins and lock, so that is the “arming” distance”. Good thing, as the blast radius of the 40mm HE round ( used to be anyway) is 5 m, so you want the round to be friendlyy safe a bit downrange.
Specs on newer rounds may have changed since my time as a Grenadier.
Regarding putting a round through a window at 150m- even the old M203 with folding sights could get that done- if the gunner actually knew how to shoot- all of the fundamentals of marksmanship come to bear.
That’s an assumption not based on much of anything really important. DI vice off balance piston driven is a poor tradeoff. Look around at the rest of the AR world- indirect piston stuff is at its death knell. Offset torque eats BCGs and uppers , has poorer accuracy, kills free floated advantages (in mot all cases) and really does not solve any problems that are supposed to exist. The recent competitions for reliability and longevity still favor the original design- M4s still go 8500 rounds before failure ( for perspective, the venerable M14 was deigned to meet 1200 MRBF....) So, if one thinks that having a rifle that can realistically shoot 50+ mags of ball ammo before failing ( w/o maintenance of any type) then the AR15 sucks.
The boutique FNs and HKs all are gone from inventory- they didn’t meet the cut while the M16A4, M4s and Mk1XXXs all run and kill...
The M27 is yet to be really proven, God Bless the Marines.
Great reply. Thanks, very informative. Now I want one, LOL.
Yup. At grenade range one boy stumbled a little and went too high - so landed too close. That's one way to solve constipation.

Thanks. That and your technical description was far better than my Armorers understanding. But he had a little too much fun in his downtime hence me being sent down to help. "You're ahead, go play with the toys" Yes sir, no problem sir.

God watch over Eugene Stoner in your care as he helped remove far more evil heathens from this world than would have otherwise been possible. Amen.
