A few people have posted pictures of their AR:Ks stripped of the rails and stock to play speedball. It looks a little funky, but it's definitely doable. Underneath all the milsim accessories it's no different than the Fly SB, so it doesn't have a problem competing.
instead of using the ark for speedball you should trade it to me for an 06speed

I actually like the Milsim extras. I've always been a fan of real guns and also I started off playing scenario, so I feel like the ark with its rails (not the butt) will give me a more comfortable feeling for speedball.just my two cents
