Introduction: USACS(Universal Shotgun Ammo Combat Shotgun)

Picture of USACS(Universal Shotgun Ammo Combat Shotgun)

This is my second entry into the contest, the USACS. It feeds from a removable tube mag and can load any type of ammunition if the ammo you want to use is no longer than an orange connector with a green rod attached. It is loosely based on the SRM Arms M1216. On average the range is 55ft and it functions very reliably, rarely  jams and when it does jam it is probably because of ammunition that is too big/small or user error. Please leave a comment bellow and vote for this in the contest.

Very cool!! Did you get any inspiration from my AMR?

Johnhall14 (author)JonnyBGood2013-07-10

Thanks, no I didn't get any inspiration from your amr,in fact I didn't know about it as I don't really check the forums.

JonnyBGood (author)Johnhall142013-07-13

A good-looking, functional shotgun with a detachable tube magazine and real-world counterpart? This is amazing! Whatever happened to choking the front page with block-triggers and slingshots?

Johnhall14 (author)An Villain2013-07-11

Thanks =D Block triggers are kind of not socially accepted by the knex community anymore =P As of what happened to slingshots, well I have no idea what became of them,people just stopped posting them I guess.

That is pretty boss bro... nice job!

Thanks =)

You are very much welcome.

Anything new your working on?

Yup, one or two things.

ok,I might try to make a lever action shotgun again.

This is really nice, and I'll be sure to vote. I had this idea before, but the small part of it that I built had a completely internal mag. I dismantled it, though, and now I regret it, but, hey, this is a really good job with this new concept! I'll vote once this is officially entered into the contest. :3

Correction: A completely internal removable mag.

ok,I wondered if that is what you ment.

Thanks,apparently it got put in the contest quickly(its in now) Thanks for the vote = )

Johnhall14 (author)2013-07-10

Thanks =D Thats an interesting name idea,I'll think about it. Also at some point in the future I might be making a lever action shotgun,I tried it once before but it didn't work out, that's were I got the mag idea at.
