I would go for the Kriss Super V submachine gun. It’s an interesting experimental weapon which is currently under advanced stages of development. 800 rpm cyclic rate and weighs a little over 5 pounds. This weapon is intended to provide operators with improved control over accuracy and bullet dispersion, in both semi-automatic and full automatic modes, while firing hard-hitting .45 ACP ammunition. The overall design also permits the Kriss to be fired single-handedly when required by tactical situations and can be done so with adequate accuracy. To achieve those goals, Kriss Super V submachine gun employs three basic solutions. First is to place the axis of the recoil force in line with the firing hand, thus minimizing the muzzle climbing. Such system was previously employed in Olympic-class small-bore pistol developed in Russia and was subsequently banned from international ISU competitions because of extremely high accuracy, which made completion "unfair". The second solution is probably more novel, as it uses a laterally moving weight, attached to the breechblock (bolt), to divert recoil forces to the bottom direction (Downwards !!). The third solution is actually a part of the second system, and it employs a variable-angle track in the weight which puts a breechblock at a mechanical disadvantage during earlier stages of recoil, thus slowing down the movement of the bolt while pressure in the barrel is still high
In other words as the round is fired, the bolt extension must first overcome an initial shelf. It then travels rearward along an upward-angled channel in the slider which pushes the slider virtually straight down the rod (vertically), which compresses the recoil spring against the base plate. After the spring reaches full compression, it pushes the slider back up, and the bolt back forward.
As a result of these measures, the Kriss Super V submachine gun has significantly less muzzle climb when compared to most modern submachine guns. This results in better accuracy and better grouping of hits on target, providing operators with greater lethality during encounters. You can watch footage of the Kriss being fired on "Future Weapons" (No doubt on youtube somewhere)

lightweight, and better than the M16A2, that doesnt jam

If i could replace the M-4 i would pretty much go with that weird looking canceled XM8 because when they did the re- test in 2007 against all competition like that new HK 416 and FN SCAR it still beat everything
It never jams and its super light weight either that or the new 6.5mm upper for the M-16.

it should have rails on it for different scopes but also needs to work in all environments with out that much cleaning. also it would be great if it was similar to the M4a1 so we don’t have to retrain all the troops

I would go with two choices: HK416 in either 6.5 Grendel, or 6.8 SPC. HK is very similar to M4, but with a gas piston, which should eliminate most jamming problems. Grendel is by far better, but would require changing the whole rifle. SPC has the same shell as the current round, so you would only change the upper portion.

There are a few major problems with bull-pups. One is their short aiming radius – downgrades accuracy, unless you use an optical sight, like AUG. Another is that the magazine is off-center – when you shot, the center of mass changes – again, downgrades accuracy.

looks like the army is giong to go with the SCAR. they’ve already given it to ranger regiment to combat test. thats a pretty good sign that its going to be taken. we might have chosen the ACR, but its still not fully developed, and their running into issues early on: the same reason why we abandoned the XM8.
the m4 was actually a pretty decent weapon as long as you took care of it properly. my only complaint about it was that it wasnt gas-piston operated. gas operated+desert environment=problems. as long as you take care of it right and use graphite instead of CLP you wont run into any issues unless you have to go extended periods of time without cleaning it.
as for what needed to be upgraded from what we had: gas-piston operation, as well as fully ambidexterous design. the m4 can be a bit of a pain for southpaws. the SCAR fixes both of those. smaller, lighter, less recoil and rise are also nice things to look for, but our current systems arent bad enough on those to where we NEED an upgrade.
