Viper52:
Yup, I just checked a picture the right side of an SAR-21 and it does appear to have a casing deflector. I can't remember where I got it from though, so I can't post it here.
Well, actually when I mentioned the charging handle was flimsy, I meant whether the mechanism that allows the knob to flip to either the left or right side would hold up under the repeated handling of NSmen. But I guess they probably took that into account. I'm just wondering why they didn't use a more straightforward design to make the charging handle ambidextrous, such as the FA-MAS type charging handle
About the ease spring feature, was this feature intentionally excluded from the SAR-21, or was it because implementing it into a rifle with a bullpup design would be difficult for whatever reason? Because personally I think the ease spring feature is a very useful feature which no decent assault rifle should go without. If it was indeed excluded intentionally, what were the reasons behind it?
Nevermind about the magazine thing then

So long as it accepts M16 magazines without any modification, its perfectly fine with me.
The three-round burst option might not exactly be very good though. Apparently during the Gulf War some soldiers were court martialed for modifying their M16A2s to fire in full-auto. I haven't had any personal experience with this so I can't say for sure whether its good or bad though.
About the ability of an SAR-21 shooter to fire with both eyes open, I too agree its one of the SAR-21's strong points, and would be very useful in a CQB situation, due to both this feature and the SAR-21's overall short length.
About the books that cover the SAR80 and U100, do you know where they can be purchased? I am rather interested in finding out more about these locally made weapons.
About the SAR80 vs the SR88, which design came about first, and about which year did both designs come out?
Actually, any rifle that is chambered for the M193 round would be able to fire the M855/SS109 round. This is because the external dimensions of both rounds are identical, since the longer bullet of the M855 round sits deeper in the casing. However, rifles which use the M855 round have to have a tighter rifling twist, in order to stabilize the heaver bullet. (M193 is 55 grains, and M855 is 62 grains if I recall correctly. What are "grains" btw?) Again, if I remember correctly, the M16A1 or M16S1 barrel has a 1 in 12" rifling, and the M16A2 or other rifles using the newer round have a 1 in 7" rifling.
The optimal rifling twist for the M855 round is actually 1 in 9" but the 1 in 7" rifling was used, so as to stablize heavier tracer rounds that may be used occasionally. The rather tight rifling twist is what I believe causes the ineffectiveness of the bullet that you mentioned.
What happens with the M193 round is that the 1 in 12" rifling is just within the critical limits required to stablize a bullet of that weight, so when it hits any obstruction such as armour or a person's body, the round destabilizes very quickly, and tends to keyhole (turn on its side). If it hits hard armour, it tends to go splat and generally not pierce the armour but if it hits a soft obstruction such as a human body, the bullet would destabilize and turn on its side, causing the bullet to split apart at its cannelure (the ring thing that the casing is crimped around) and fragment. This causes the horrible wounds that were documented in the Vietnam War, when the M193 round was being used. The bullet would normally blow out huge chunks of flesh and create large wounds that would result in massive bleeding and a quick death, especially if fired at ranges closer than 25m. Also, if the bullet fragmented, the lead fragments from the bullet's core could cause lead poisoning if not removed quickly, and this was generally very hard to do since bullet itself was already rather small, more so for the fragments.
As for the M855/SS109 round, the tight rifling twist makes the round very hard to destabilize even when it hits obstacles, so it normally just "drills" and punches through the target. This would make it more effective against armour, but rather ineffective against personnel, because it would normally create a very small and neat wound, and normally with very little loss of flesh. And since the bullet doesn't even remain in the body, the wound is both minor and usually heals rather quickly, provided the wound is sterilized and bandaged properly and that the bullet doesn't hit any vital organs. Against personnel with body armour however, I think the train of thought was that the armour would sufficiently destabilize the bullet to the point that it would have the same effect on the body as the M193 after it passed through the armour.
So actually, I'm just wondering what the rifling twist of the SAR-21 is. Is it a 1 in 9" twist that would cater to most types of bullet weights, or would the barrel have to be swapped if different bullet weights to be used? I also recall reading that older M193 bullets used in rifles with a 1 in 7" rifling twist would sometimes explode after leaving the barrel due to the increased centrifugal force. I'm wondering if this is true, because it doesn't make much sense to me since the bullet diameter remains the same. I think the quality of the bullet might be the case here, or maybe the M855/SS109 round is specified with a thicker jacket. Does anyone know more about this?
What was the difference in the way you had to hold the SAR80? Just curious cos I've never touched an SAR80 before

As for the added weight, I would gladly use a lighter and (allegedly) less accurate weapon, and carry more rounds, instead of a heavier weapon, whose accuracy may or may not (arguably) make a difference and not allow me to carry more rounds. So yea, I would prefer an M16 over a SAR80 anytime as well

Ahh yes... the country I was trying to recall was Croatia

Thanks for refreshing my memory. I read somewhere that the U.S. Navy Seals use the U100 too. Is that true or just bullshit? I personally feel the pistol foregrip of the U100 is a little on the small side though. (I got to handle it once before)
Raider:
The SA80/L85A1 is a totally different rifle from the SAR80, just that the lack of an "R" confuses people sometimes. The SA80 name is actually the name of the rifle when it was still a prototype design. The correct designation is "L85". The L85 is a bullpup rifle, and apparently its extremely problemetic. The SUSAT 4x sight is supposedly very fussy with temperature variations and the earlier-issued ones fogged up internally after a while and there're no backup iron sights, if I'm not wrong. (correct me if I am) They did try to fix it up, but its reliability still leaves a lot to be desired. Its wierd, since the L85A1 was essentially, supposedly a redesigned AR18/AR180 in a bullpup configuration, and the AR18/AR180 was a reliable weapon. Also, though the L85A1 is manufactured using plastic furniture and sheet steel stampings, it still manages to be rather heavy. (3.8kg without a loaded magazine and the optical sight, and 4.98kg with both the sight and loaded magazine) Its supposedly heavier than an L1A1/SLR/FN-FAL. I don't have the info on hand at the moment so correct me if I'm wrong.
Silenthunter:
They have supposedly asked H&K to troubleshoot and improve the rifle, and when re-issued it will be designated the L85A2. If I'm not wrong, this hasn't happened yet, unfortunately

Eyezer:
I think the Taiwanese use the M16A1...maybe they were using the L85 for training exercises to simulate a "worst-case" scenario. hehehe

If all I've read about the L85 is true, then its probably one of the most poorly recently designed rifles.
Anyway, this is a picture of an L85 I managed to find:
