The IBRAP Alfa GP-1 is a prototype Brazilian submachine gun.

HistoryEdit

The Alfa GP-1 was designed in 1987 as a project by Genaro do Prado. The weapon was apparently submitted for trials, but no documentation exists; even if it were submitted, the weapon never exited the prototype stage and never entered serial production. A variety of sources state the GP-1 performed well during the aforementioned tests, although there is no documentation to prove this.

At least two prototypes were built, although none appear to exist today.

Design detailsEdit

The GP-1 is a blowback submachine gun in essence, although it does have a variety of features that are considered a little bit odd on a firearm of its size. The weapon's main features include two pistol grips; the front grip holds a spare magazine and was added to the weapon to apparently help "speed up reloads". The weapon appears to have a very small charging handle on the right hand side. The weapon's selector switch is on the left of the weapon.

The weapon has rings machined onto its barrel supposedly to help with cooling the barrel. The weapon features a grip safety. The weapon's bolt is said to almost recoil upwards. The first prototype had a folding stock which folded to the right of the weapon. The first prototype also had provisions for a bayonet.
