INTRODUCTION
The SUB 2000 is a semi-automatic rifle chambered for the 9
mm Luger or the .40 cal. S&W cartridge. Different versions of
the SUB 2000 rifle will accept most double column handgun
magazines, e.g. S&W, Glock or Beretta. By rotating the barrel
upwards and back, the SUB rifle can instantly be reduced to
a size of 16 x 7 inches to facilitate secure storage.
The small size, light weight, and the use of a pistol cartridge
would imply the prefix "sub". Thus we have found it
appropriate to classify our firearm a "sub-rifle". The SUB
2000 rifle is intended as a compliment to the handgun with
which it would have full interchangeability in ammunition and
magazines.
The SUB rifle will have much better accuracy and deliver
higher muzzle energy than the short barreled pistol. Thus,
the SUB rifle has a greatly extended range compared to a
handgun. The superior precision is also very useful against
small or partially covered targets at shorter range.
CONSTRUCTION
The receiver is made of an impact modified glass reinforced
Zytel. The front end houses a hinge block holding the barrel
and rear sight.
This block is securely locked in place by a swiveling trigger
guard. The receiver rigidly attaches to the stock by multiple
lugs. The bottom forms the grip and also accepting different
magazines according to the version specified. The receiver
also houses the firing mechanism.
The barrel has spring loaded collar to ensure an accurate
lock to the receiver, a polymer forend and a fully adjustable
front sight. The forend is designed to house batteries or other
devices.
The tubular steel stock contains the bolt and is ended by the
polymer butt stock.
The heavy two-piece machined steel bolt holds the firing pin,
the extractor, and has the operating handle on the bottom. A
captive guide recoil spring with buffer actuates the bolt. The
long bolt travel allows for very large functioning marginals.
The firing mechanism is of conventional single action type.
It has a positive disconnector, a push bolt safety that blocks
the sear and disengages the trigger bar. The hardened steel
ejector is internal and also holds the engraved serial number.
