According to wikipedia, they used it because the War in Iraq at the time made it difficult to get hold of P90 cartridges. No idea if that's true or not. Do they even use the P90 in Iraq? I wouldn't have thought so.

Is that an A2/A4 stock? Noveske Rifle Works and LWRC are two companies that offer 7.5"/8" M4s (both have rifles with that barrel length chambered in 5.56mm and 6.8mm), off the top of my head. I think Diemaco also has a 7.5" or 8" PDW M4. Regarding effectiveness, if it were chambered in 6.8mm it would be much more effective than if it were chambered in 5.56mm (6.8mm FMJ rounds fragment at lower velocities). That being said, they could have changed the powder the 5.56mm FMJ rounds used with something that burns a little faster to get more velocity out of the shorter barrel.His Divine Shadow wrote:Looks like a custom AR based gun. you can see the common AR features, the forward assist, brass deflector, 100 round betamag, forward vertical grip, looks like a railed free float handguard.
Other mods include no iron sights, maybe a 7.5" barrel barrel (which really reduces the effectiveness of 5.56 with regards to range). I dunno any particular brand for this gun, the closest I've seen would be the HK-416. But it doesn't look like one of those. Thats a weird stock too.
I'd say some movie props guy throwed together sometihng that looked cool without regards for effectiveness.
Very unlikely that they use the P90 in Iraq. Who would use it, the P90 isn't a widely sold weapon (20'000 weapons sold, according to Modern Firearms).Revy wrote:Here's a better pic of it, or at least a replica of it;

Yeah, it just saw that it wasn't an A2/A4 stock when Revy posted that other picture of it. It's what they use in California, so that they don't have an evil pistol grip which will assault all the children...think of the children!His Divine Shadow wrote:Nah that stock looks like some of the weird shit they put on in states where evil features like pistol grips are not allowed.

It has failed at that, which militaries use the P90 as an SMG for artillery crews, vehicle crews etc?The FN P90 submachine gun (SMG) was developed in the late 1980s as a personal defense weapon for the troops whose primary activities does not include small arms, such as vehicle and tank crew members, artillery crews etc. Standard pistols and submachine guns chambered for pistol rounds were proved ineffective against enemy soldiers, wearing body armor; Therefore FN designers first developed a new round with enhanced penetration, initially known as SS90.
Most interesting fact about adoption of P90 is that so far it has been adopted for the role, directly opposite to its original niche of "personal defense weapon". In fact, most services and agencies that adopted P90 use it for offensive roles, as a specialist or even a primary weapon for various assault teams, and other "professional small-arms users", as opposed to military personnel which primary functions do not include use of small arms.

Of course, none of this answers the question of WHY they are not using Zats as a secondary weapon. The writers have been asked that question more then once and they acknowledge that it would have made perfect sense for the initial expedition to carry them, given their absurd endurance and relative effectiveness, but they wanted to really keep the show separate from SG1.
Don't you mean to say, that fact that FN says neither of those fears are problems is beside the point? The ammo rotation mechanism has to rotate the rounds 90 degrees, sounds like it just complicates the weapon (and makes it prone to ammo feeding related problems), in order to change the position of magazine from the butt to the top.Timotheus wrote: I said what it was designed to do. Not what is has started to do. Lots of bad press and rumor have really hurt the P90. Fears that the clip will pop out when dropped or that the ammo rotation mechanism will jam easily have really hurt the use of the weapon. The fact that neither of these is true is besides the point.
Timotheus wrote: The P-90 is very accurate for its size because of its bullpup design and carries more ammo than a MP5.
How is it superior to the MP-5? Why isn't the MP-5 being phased out in large numbers in order to be replaced by P90s? Popularity is the most important category for the selection of a weapon...are you fucking retarded? BTW, American SWAT teams are phasing out the MP-5...in favour of the M4, not the P90. I suppose your last two sentences are a concession that the P90 is a new, fun toy?Timotheus wrote: In every category other than popularity it is a superior weapon to the MP5. Obviously popularity is the most important category since the MP5 continues to be the more common choice. You do see P90's though used by the swat teams of yuppie towns with excess money and a desire for the newest toys. Towns that really have no need at all to possess a swat team.
In exchange for common ammunition between the P90 and it's smaller, equally retarded relation, the current weapons would have to be phased out (which likely share the same calibre ammunition) in exchange for a family of weapons which aren't in widespread use, and which use more expensive ammuntion, until its produced en masse, in quantities like 5.56mm or 9x19mm. In the case of the US military, for example, the troops that would potentially carry PDWs are already using M4s. The P90, like pretty much every other PDW (other than the KAC or Magpul prototypes) are pieces of shit that are ballistically less effective than a carbine or rifle.Timotheus wrote: It still is the best choice out there for its intended purpose. It has a better punch, more ammo, is ambidextrous, and was designed to be easier to use than any other weapon you would compare it to in this area. It also uses the same ammo as the 5n7 handgun which would allow a military that used it to cut out one item in their supply requisite.
Perhaps the most interesting recent development has been the Russian adoption of the 9 x 19 round, just as NATO was searching for its replacement. In this case, the 9 x 19 is seen as significantly more effective than the long-established 9 x 18 Makarov (an attempt to boost the performance of the Makarov round up to NATO 9 x 19 levels with the 7N16 high-pressure loading was abandoned because of the danger of using this in older guns). The effectiveness of the new Russian 9 x 19 is significantly enhanced by the development of new loadings which combine the ability to pierce body armour with the benefits of a full-calibre bullet against unprotected personnel. It achieves this by means of a method of construction which is similar to that of Second World War APCR, HVAP and PzGr 40 anti-tank gun projectiles: the bullet has a hard sub-calibre core contained within an outer sleeve and separated from it by a polyethylene layer.
If the bullet strikes an unarmoured target, it holds together to produce a wide wound channel. On impact with armour, the sleeve is stripped away and the core penetrates alone. Two different loadings have been introduced: the 7N21 (5.3 g at 460 m/s for 560 J muzzle energy) and the 7N31 (4.2 g at 600 m/s for 756 J). The latter in particular is a very high-pressure loading which can only be used in particularly strong pistols. Not satisfied with improving the 9 x 19 in this way, the Russians have also introduced a longer 9 x 21 round for special forces weapons to achieve the same effect. The 7N29 AP loading fires a 6.7 g bullet at 410 m/s for 560 J, and will reportedly penetrate two 1.2 mm titanium plates plus 30 layers of Kevlar at 50 m. This Russian approach appears to provide the best of both worlds. The disadvantage is that high impact velocity is needed for this to work, so the bullets (especially in the 9 x 19) are relatively light to maximise the muzzle velocity. This does mean that they will lose velocity relatively quickly, limiting their effective range.
Another problem is that the 5.7mm round is anemic at wounding. About as effective as .22LR. The Level 3A body armour can be penetrated by 9x19mm ammunition, which is what the Russians use, while still being more effective against than what the P90 brings to the table.phongn wrote:The Royal Thai Army tried using P90s for their MPs, but apparently found it rather suboptimal (the magazines were prone to spilling ammo if you dropped them, there is no bayonet and you can't use it as a club).
Yes, it makes such sense. By that logic, we shouldn't be seeing Asgard beam weapons on 304s going to Atlantis, because it was on SG-1. Hell, the Asgard shouldn't have been on the Daedalus in its first few appearances, as they were an SG-1 race (its not like his inclusion was actually necessary). There are countless crossover technologies they've made use of, not to mention whole reused plots. They're not fooling anyone if they think the lack of zats give the feeling of a clean break with SG-1.Timotheus wrote:Chris OFarrell wrote: but they wanted to really keep the show separate from SG1.

"The article 'FN's FiveseveN System (No.v/Dec. 1999 p.40) seriously misrepresents the wounding capacity of the 31-gr. P90 bullet. Claiming it "produces a wound cavity that is similar to that of the 5.56 mm NATO ammunition is an absurd exaggeration. The 31-gr. P90 bullet has only half the weight of the M16A2 bullet - and its velocity is about 1000 f.p.s. less. [(The reference was intended to convey that it is an FMJ design, not that it has equal energy and wounding characteristics to the 5.56x45 mm cartridge. - The Eds)].
The amount of tissue disruption propduced by the P90 bullet is less than one-third of that produced by a well-designed expanding 9x19mm handgun bullet. And the P90 produces a temporary cavity of only about 8cm diameter - smaller than that of an expanding 9mm handgun bullet. Most of the P90's bullet's wounding potential is wasted in producing a temporary cavity that is too small to be a reliable wounding mechanism. The P90 bullet doesn't even come close to matching the wounding capacity of a well-designed, expanding 9mm handgun bullet.
The light recoil of the P90 should hardly come as a surprise: The momentum and kinetic energy of its bullets are only about half that of the .22 Hornet bullet. The P90 bullet's wounding potential is about equal to that of the .22 WMR bullet. The laws of physics cannot be denied - minimal recoil is inconsistent with maximal tissue disruption.
For the military, where any wound is often all that is required to cause an enemy soldier to leave the battlefield, perhaps this tiny P90 bullet is OK. Law enforcement officers are often faced with armed violent criminals at close range. In that scenario, a bullet capable of disrupting a significant amount of tissue is needed: One must incapacitate a criminal, a minor wound will not suffice. By no stretch of the imagination is the P90 bullet adequate for that task.

[(The 5.7 was designed primarily for a military and special operations role, not as a duty cartridge for typical law enforcement officers - The Eds)]
Other than being able to perforate soft body armor, the 5.7 x 28 mm used in the FN P90, as well as the 4.6 x 30 mm fired from the HK MP7 cause wounds less incapacitating than those made by 9 mm FMJ fired from a pistol.
I have personally fired the 5.7 x 28 mm FN P-90; velocity, penetration, and tissue destruction is like a .17 Hornet--far less than we see with 75 gr TAP or 77 MK out of our M4’s. Winchester RA45T 230 gr JHP’s fired from our duty 1911’s crush more tissue and penetrate further than the 5.7 x 28 mm. Use of the 5.7 x 28 mm is a good way to ensure mission failure.
Several papers have described the incredibly poor terminal performance of projectiles fired by the FN P90.

--Roberts G: “Terminal Performance of the 5.7 x 28 mm 31 Grain SS-190 FMJ Bullet Fired by the FN P-90 in 10% Ordnance Gelatin.”, AFTE Journal. In Press.
The early 5.7 x 28 mm 23 gr FMJ bullet fired by the FN P-90 had insufficient penetration for law enforcement and military use. The current 31 gr SS-190 FMJ bullet has nearly adequate penetration, but the wound resulting from this projectile has a relatively small permanent crush cavity, as well as an insignificant temporary stretch cavity. Although the 5.7 x 28 mm penetrates soft body armor, wounding potential is at best like a .22 LR or .22 Magnum. Even 9mm NATO FMJ makes a larger wound--and we are all aware of the awe inspiring incapacitation potential of M882 ball from the M9......
Numerous other projectiles commonly used for law enforcement and military special operations applications, such as a good 9mm, .40 S&W, or .45 ACP JHP, the better 5.56 x 45 mm BTHP/JSP loads, as well as 12 gauge shotgun slugs and 00 buckshot, all provide better penetration, crush more tissue, and have far greater potential to reliably physiologically incapacitate an aggressor than the 5.7 x 28 mm 31 gr SS-190 FMJ bullet fired by the FN P-90. Law enforcement agencies and military special operations units are strongly urged to avoid adoption of this weapon system.
I really don't see this ISD thing. Anything that has a point and has a very remotely looking tower at the back is now an ISD copy? I don't get that, and I certainly don't see the resemblance.

While I can't disagree with you that I don't want another super-race clone, that final battle with the Replicators is by far not the best example to pull out as to their vulnerability. The writers had them practically pulling their punches at every opportunity. Not a single drone fired, their shields were pitifully weak, and they weren't able to destroy a single Hive, something they had been achieving all throughout their campaign against the Wraith with ease after McKay reprogrammed them. If there sensors were as good as Atlantis', and I can't believe they aren't, they would have detected the incoming fleet and ambushed them when their shields were down (something that this episodes demonstrates is an impossibly small window, while other episodes have it on the order of several seconds). I'd almost call that battle a case of writers fiat (although anymore, what episode of Atlantis isn't?).Well, hopefully this is a sign that the new foes will not be an "OMG SUPERRACE WE HAVE NO HOPE" followed by a Dues Ex Machina. The one thing I liked about the Anchient Replicators was that they were not a invincible force until they weren't(Ori I'm looking at you). Had some technology superiority, but 304 were a match for them.
I agree. From a perspective of making the Wraith a cooler foe (and making them not, you know, suck), Todd really needs to be taking a more proactive stance. If I got my wish, there would be a two-parter in a couple episodes where Todd plays Atlantis against Michael somehow, gets him and his lame Hybrids wiped out for good, maybe by some miracle gets the Daedalus destroyed or shot up in the process, and generally rallies at least a bit of what's left of the Wraith "menace" to some degree of competence. I forget, does Todd know the current location of Atlantis? I thought he did from "Be All My Sins Remember'd", but I don't know for sure.CaptJodan wrote: I suppose they've tried that with Michael, but I'd much prefer with stick with Todd. He seems to be the Lord Yu of Atlantis at this point.
I could probably find the actual blog entry but I'm too lazy. Well, if that's true then so much for these new aliens, guess we're stuck with Michael and the Wraith for the rest of this season. All I can hope for is that the Wraith either get wiped out this season or something happens to make them much more formidable.Regarding the new alien race: "It's unlikely we'll see them again this season."

Nope, they definitely came off as being much tougher. Aside from the physical confrontation, their ship surviving a direct hit from a beam-weapon was pretty telling as to their capabilities.

Physically they seem to be quite strong too. The alien caught Ronin's pistol arm as he was about to bring it up to fire, slammed him into both sides of the door jamb, slammed him into the wall twice (once the whole body, had him pinned and slammed Ronin's upper torso) and then tossed Ronin on to the floor.

Regarding the Wraith, was their resilience to bullets less in episode 3 than in the rest of the seasons? Perhaps those particular Wraith, or the Wraith in general, haven't been able to feed enough to shrug off the effects of being shot multiple times.
