Folks, this is just a hypothetical question, I do not plan on doing this but it is something I thought about for a brief second while at the range yesterday.

 

Is it legal to mount a shotgun onto an AR15 in NJ?  If yes, has anyone here done it?

If the shotgun still has an 18" barrel, and is a pump

KAC makes/used to make a kit called the "Master Key" and the Remongton 870 MCS that the Army uses has the parts to attach a breaching shotgun to an AR.

 

Or you could use a Mossberg like Billy in Predator:

 

If you follow what 302w said and use an 18" barreled pump gun you should be good to go. It's just gonna be heavy.

that would be fun to take to the range haha

I believe you can get a SBR stamp and do it with a shorter shotgun - in a free state.

It would be cool to have the rifle and shotgun together.

My inner retro enthusiast is cringing.

 

Partial fence lower, slabside with no foward assist upper, then put on a blasphemous A2 handguard with (I think) A2 barrel?! Noo!

 

I'll let the BCG slide.

Hrmm - how many shotgun blaaaasts (/Joe Biden voice) do you get before you start to worry about the takedown pin holes in your upper becoming oval instead of circular?

To much COD?

If you mount shotgun on an ar, the shotgun might be an evil feature if it could be called a grenade launcher. But what if you mounted an AR on a pump shotgun?

That's actually what I was thinking, we cant mount a grenade launcher, shotgun would be the next best thing.

 

If I was crazy enough I could mount this

On this

A million - If the shotgun is mounted properly and you are shooting appropriate loads. Keep in mind that this design is intended for breaching not fighting. That means the system is designed to shoot breaching loads, not to be a fighting shotgun shooting 3" magnums.

 

Manipulations on both platforms become more complicated and there is no way to really aim the shotgun accurately.

 

It is actually easier and let's you accomplish each job - breaching & fighting - more efficiently to carry the two platforms separately. Most guys I know (me included) choose to carry an AOW or SBS for dedicated breaching duties and a retain a lighter handier rifle for fighting.

 

An AOW or SBS something like this:

carried weak side on your armor or back works very well.

 

Accordingly this "Master key" type set up sees little use outside of dedicated breachers.

 

You can see the mounts here:

Remington MCS system:

 

Knights Armament Co "Masterkey":

 

This is the latest iteration of this concept - the M26:

 

By all accounts (my brother was issued one in SRT training for a a while) it is an abortion of a weapon that does nothing well.

I like be 10" breaching weapon above.

Hiyo!!!

Masterkey setups are stupid and pointless but cool. Like something you drunkenly buy on eBay.

Try it with an SMG instead for a much more fun result:

And, Yes, he did make "some" and people have them.
