the brickarms ac8 is possibly brickarms best assult rifle in production, works as a deadly modern weapon, to a sleek and stylish sci fi weapon! also it has more modding possibilities than most other weapons!
the ac8 is a great example of how brickarms prototyping works, as the ac8 had a long battel on its v2, but it had alot of glitches, like an oversized handle, and the inability to make a minifig grip under the rail. the v3 was improved, with a fixed grip, and the ability to put a minifigure hand under the rail, but the mag was wider than it needed to be, then, the v4 came, aka, the production one, the one we can now buy on brickarms.com!
