The Cellular Ammunitium Rifle Base (CARB) GS-221 is a automatic assault rifle that is produced by the spanish Matanza Arms Corporation. the GS-221 is a bullpup designed weapon, which means that magazine is located in the stock of the weapon, which cuts down the length of the weapon while not needing to minimize the barrel. That lets the user have a smaller rifle with the same full-size barrel length. however, there is also a short barrel version of the GS-221, which is ment tio be a PDW. The full size version has a AR-15 styled foregrip with R.I.S rails, that lets the user mount all sorts of attachments and accessories, such as a optic sight, or tactical tourch,, the rifle aslso has a quick-attach mount under a barrel that can be used to mount a foregrip, or a 20mm launcher attachment. The GS-221 has a polymer box-type magazine, that has a 80 round copacity. and the magazine rlease switch is founch on the bottom of the pistolgrip and has a ambidextous fire selector switch. The GS-221 has three firing modes: safe, semi and fully automatic fire. The ejection port is located on the right side of the weapon. The rifle also has a dust cover that provents any dirt from getting into the internals. The GS-221 has a M14 style bolt is found under the dust cover, which has a screw-type removable charging handle, that screws in to the M-14-style operating rod, allowing the user from pulling the bolt back and blocks the firing pin. Note, that the dust cover can only be closed when the charging handle is not screwed in to the bolt, A version without a dust cover and a fixed charging handle also exists, were the ejection port has been extended to the buttstock to accommodate the full-size charging handle. The bolt stays in the rear position after the last round has been fired.
