The SRC A7 B-Spetsnaz Full Stock is the airsoft version of the real steel AKMSU. The AKMSU’s barrel tip has a customized muzzle brake that looks interesting. For increased heat dispersion, it has many grooves machined into it. The hand guard of the AKMSU has a unique thumbhole foregrip.
The SRC A7 B-Spetsnaz is a high quality airsoft gun with full metal construction. The following parts are made of composite ABS plastic: the foregrip, stock, and the textured grip. The foregrip has a very comfortable thumbhole grip. It comes with a metal gearbox for durability. As to the big flash hider, it has a standard 14mm counter clockwise thread. So, you can replace this with after market flash hiders. Its magazine is metal with 600 round capacity. The fire selector switch has semi, auto, and safety and it clicks firmly in place. This means it can’t be accidentally moved easily.
There are two rails on each side of the foregrip of the SRC A7 B-Spetsnaz. The foregrip itself can be replaced with most of the short 74U style after market foregrips out there. Performance wise, this gun is more than decent. Firstly, it shoots an average of 280 fps which is within the limit for CQB. Secondly, you can easily hit a man-sized target at 100 feet and the maximum range is 150 feet. This is amazing range for an airsoft gun with a very short barrel. Moreover, the rate of fire is around 900 rounds per second which is pretty respectable overall. Worth mentioning, the roomy battery compartment in the stock of the gun is large enough to accommodate large battery types.
The SRC A7 B-Spetsnaz package includes the instruction manual, metal hi-cap magazine (600 rounds), battery & charger, sample BBs, cleaning rod, and steel flash hider.
