    With a circular barrel, this could definitely be an LR-300 or M4A4

    Threw a rock at a wall, made a dent. Its amazing

    Cut rods shouldn't be a con you guys have to start dealing with it.

    But try to build something else than yet another m16 like gun

    i got around 40ft, but that depends on the bands. I already started on a new one though.

    What kind of gun is it going to be?

    Nice if I get some time I'll build it.
