Hk416 + m203?

[SpartanWarrior198]

I'm sorry for sounding noobish, but does anyone here know if the rail system used on the HK416/417 accept an M203 or 203A1?

[SMGLee]

M203 mount to the barrel, HK 416 rail is one piece, use a LMT MRP style rail mount M203, you can't use a M203 with the HK416. even if you run the gun with out the rail, the barrel nut are different...

To supplement what Chen was saying,

HK also makes 40mm UGLs that also attach onto the rail system. But by looks, the LMT 203's more streamlined and not as 'bulky.'

[SpartanWarrior198]

Yeah, I've seen LMT's RIS-mounted version of the M203 before. I've just been curious as to whether our issue 203s can fit or not. Thanks for clearing that up for me, Lee.

I do agree that HK's AG36-style launchers seem quite bulky, at least from a visual standpoint, when attached to anything but a G36, though.
But I'll definitely be looking forward to the possibility of reading field reviews from US troops on here when those new M320s start seeing use come February.

AG36 = M320, no? Looks the same atleast...

Compared to HK79 which we used before, the AG36 is a charm to fire, both standalone and mounted on our 416's. Only two nags i have with it is that, 1, being left-handed it's not the easiest thing in the world to aim it, and 2, the trigger is quite hard and it seems to take forever from you start to press the trigger to the shot goes. Last part i believe is only a matter of practice and getting used to though. As for the first part, it's possible to detach the sight and mount it on the other side for left-handers, but then you create a problem for all the right-handers who are going to use it.
Included allen-key to "zero" (yeah, zero 40mm low velocity on a low'ish-precision sight is sort of an oxymoron isn't it?) is also a plus, if the sight gets a bad knock or for some reason is way-off.

We're thinking about self-modding the thing and mounting the sight on top of the front-rail, to accomodate both left- and right-handed shooters, just have to give it some thought on how and see what the armorer thinks about it first.

Another big plus over the M203 style is that a side loading launcher is able to accomodate full-length munitions, although i've never had anything to do with munitions that use the whole barrel, crowd dispersal rubber-shot being sort of the exception, at half-length or thereabouts.

I didn't say the M320 is the AG36, because it's not. But it was still developed from the AG36 platform.

Definitely, compared to the HK79, the AG36 is tiny. The HK79 is a heavyweight monster.

But the lengthened breech also enables shooters to chamber and fire high-velocity grenades intended for automatic grenade launchers.
I could be wrong, and if I am, please correct me, but doesn't that pose possible harm to both launcher and, more importantly, shooter?

You sure about that?

[SMGLee]

You sure about that?

I am sure it will blow the gun up.....well I mean blow the launcher to kingdom come! the HK AG36/M320 is not built to handle the high velocity round out of the Mk19.

yeah, thats pretty much what we've been told the effect will be. We joked about who would be the first moron to try it when our AGLs come on line. I haven't had any issues with the variety rounds we use in our 203s (M-203 PI, made by some company in Miami) the longest rd we use is our Illum rds but have plenty of room to load them.

probably it's a pic of one of the first prototypes of the 416 which had the conventional m4 style barel...

It's definitely not like any 416 I've seen before (picture-wise, not in person). For one, the hand guard has no side rails. And most notable is the locking thingy (can't think of the name) that holds the rear of the hand guard in place. SMG's pic doesn't show one, and none of the pics I have in my collection (like the one below) have it.

My guess would be that it's an early prototype, like zema suggested.

Upon closer examination, the pic posted by mikec62001 looks like it could just be an Vltor upper attached to an HK lower (assuming such a conversion is possible)

Referring to what?

[Lerch]

It's possible, and it is ;)
