Re: Israel Foreign Legion
The Steyr AUG with the patented modification being a rearward facing Beretta 90two grip at a forty-five degree angle in place of the AUG’s original rear grip. The 90two grip is to be scaled up to a .45 ACP length action or approximately that size, for a more positive grip to improve weapon control. The reasons for this modification are that leverage is more efficient concerning transition speed than is cradling the rifle and multiple planes off of the bore improves pointabilty. The 90two because the significance of the open top slide is that pistol points off the barrel; grip angles are discussed in Col. Charles Askins – Souped Up Man Stoppers http://i46.servimg.com/u/f46/12/96/69/50/askins10.jpg http://i46.servimg.com/u/f46/12/96/69/50/askins11.jpg http://i46.servimg.com/u/f46/12/96/69/50/askins12.jpg http://i46.servimg.com/u/f46/12/96/69/50/askins13.jpg http://i46.servimg.com/u/f46/12/96/69/50/askins14.jpg http://i46.servimg.com/u/f46/12/96/69/50/askins15.jpg. The 90two has suppleness that like breaks the momentum http://www.aero-news.net/index.cfm?do=main.textpost&id=7a278c48-3142-4a08-b72c-9aa98e02a7bd that makes for the synergy with the open top slide. The 90two because 92 having the edges of the grip filled in where the grip plate on the 92 ends gives a more complete feel. The 90two grip being mounted rearward is leverage. The AUG because it’s a bullpup and the off by forty five degrees square stock is good for pointability as the non-trigger hand is now to grip the stock behind the rear optics rail mount. The Beta-C Mag balances the rifle and rests against the trigger hands forearm to improve pointability. This rifle is hereby branded as “Beretta” and named the “St. Clair Isoldi CLS II S2K”.

Bullpups are naturally balanced in a non-instinctive way.
This is really the biggest problem, and the one that is hardest to solve with engineering.
The balance point on most bullpups is in between your hand and your shoulder when mounted, which is unnatural. We have a natural tendency to try to balance things between our hands, not between our hand and shoulder.
The only way to correct this is to put heavy things in front of your dominant hand, or to make the weapon short and light enough that this won’t make a difference (and even then it will still be more awkward and less instinctive to point; but several modern bullpups have taken the second approach).
This balance will tend to make a bullpup tend to shift its butt under recoil, unless it is very tightly mounted to your shoulder; particularly during rapid fire. This tendency is somewhat countered by the position of your support hand so far forward on the barrel, by the fact that the overall leverage moment of the muzzle is lower (the muzzle isn’t as far from either your shoulder, or your dominant hand), and by the fact that most bullpups have straightline recoil.
A conventional rifle is balanced in between your dominant and support hands, and there are good reasons for that. A human being naturally handles things that balance in the palm, or in front of your dominant hand, better, because we naturally want to balance things between our hands.
Under recoil, the muzzle of a conventional rifle rises, but just from gravity will fall into you support hand again without actually holding or pulling it down, because the fulcrum of the lever is in your dominant hand, and the balance point is in front of the fulcrum.

Question: Why 45 degree angle grip?
Answer: The whole 45 angle is normally just a prefrence. while offering more control when using short burst the recoil helps tug the stock. thus a more stable rifle. it may seem like a weird thing but even at single fire its a very helpful attachment for marksmen who want rounds on target A box style.
