21 BB Mid-Cap Magazine for SKS [S&T]

The SKS-45 AEG magazine by S&T is a polymer magazine with a 21 BB capacity, designed for the electric airsoft replica of the historic SKS carbine. Its construction features installation beneath a hinged metal magazine cover and a strong spring with an extended follower travel, supporting consistent BB feeding during shooting.

Magazine Construction and Installation

The magazine is made of polymer and features an elongated, wedge-shaped body designed to fit the SKS-45 AEG replica.

Installation requires opening the hinged metal cover that replicates the original SKS carbine magazine. Once the polymer magazine is inserted into the magazine well, the cover must be closed.

Concealing the polymer magazine beneath the metal cover helps preserve the historical profile of the SKS carbine without visible changes to its external appearance.

BB Feeding Mechanism

The magazine holds 21 BBs and uses a strong spring to push them toward the feed opening. The spring pressure may positively influence the smoothness of BB feeding during shooting.

A distinctive feature of the design is the magazine follower, which extends beyond the edge of the feed opening when the magazine is empty. This allows it to push the final BBs toward the feeding mechanism, helping to utilize the magazine's full capacity.

SKS - Historical Background

The original Soviet SKS semi-automatic carbine was equipped with a fixed box magazine holding 10 rounds of 7.62×39 mm ammunition. It could be loaded from above using individual cartridges or a stripper clip.

The original magazine featured a hinged floorplate that allowed the ammunition to be unloaded. Later modified versions of the SKS also used detachable magazines of various capacities.

Compatibility

The magazine is specifically designed for the S&T SKS-45 AEG electric airsoft rifle.
