IFC #410ARUM 410 Bore Upper Receiver for AR15 Lower

What's the intended purpose of such a contraption? .410 doesn't seem to be useful enough, cheap enough, nor fun enough to make such a thing worthwhile.

The other part is that if you are interested in a new shiny, $400 could get you into a "real" shotgun.

A semi-auto rabbit gun?
Someone wants a mate to their Judge?
It wouldn't be bad but it's not ideal IMO, and I'd admit it would play heck on squirrels and 9 rounds of 4-ball buckshot or .410 slugs hardly sounds like something I'd want to stand in front of.

The closest I have come to having experience with a .410 AR 15 upper was actually being talked out of buying one by a worker in the Pawn/gun shop I was looking at it in.

I was sort of thinking it might be fun and perhaps useful as a Home Defense firearm when loaded with one of the Buck shot or disc loads worked up for the .410 revolvers.

I never had a Pawn shop guy talk me OUT of a purchase before!

Hey, if you have the money and it looks like fun, go for it. Be sure to post pictures and a good review for the rest of us, please.

I guess I may need to rethink my firearms 'accumulation'. I never realized I should even be considering the intended purpose - "it just looks like it might be fun" has often been enough of a reason.

"might be fun" is absolutely a good enough reason, if you have a clear concept of how that fun will happen. Otherwise, it's probably best to redirect those funds towards toys that will actually leave the safe.

I just have a hard time thinking of things to do with a .410 that would be improved by an increased rate of fire. .410 is an expensive solution to the problem of using too much gun for the job; eight rapid follow up shots... why?

If the upper runs flawlessly on the OP's lower, it sounds like a good candidate for a HD gun, if all the rails were gone and the barrel was 16" with the short M4 fore end. The mags/availability are spendy and seem to be in question.

In its present configuration, it seems to be an answer to a question no one except the inventor/manufacturer asked.

Well, of course it is! I've bought stuff for that exact reason. If you have the money and think it will come out of the safe often enough, go for it!

Unfortunately, I'm broke enough I have to be too pragmatic. But if you're an AR user and want a rabbit gun, and this turns out to be reliable, I could think of worse.
Unless I was itching for variety (I do) and instead wanted to standardize my safe, it would be good to keep the same manual of arms.

When i break out my Saiga .410 at the Skeet range, it definitely draws some funny looks.

If it floats your boat go for it.

I have grown up hunting with a 410. It is the perfect size for squirrels and rabbits. So there is plenty of usefulness in the gauge. Point said. The ammo question I will now also debunk. It seems to work better on Estate ammo that can be bought on Sportsman's Guide for .44 cents a round. Cheaper if you buy bulk. About the same for 5.56. It is a bit finicky on the ammo. Winchester does not seem to cycle, but I don't shoot dirty Winchester anyway. Until breakin I did have a few jams. About 2 out of 100. But none since that time. CenterFire Systems has the extra mags. for 17.99 19.99 and 24.99. I have the VEPR 12 in two versions, and was looking for a shotgun AR and did not like any thing that I found until this.
It looks and acts like an AR. Not a ugly copy. Replace the sights though. It is good gun with the correct ammo. And very cool at the range.

BTW it will not work on an DPMS lower. Anderson is the lower recommend. You may have to use a shortened hammer if building millspec. But I use Timmy Triggers and CMC they bit work fine.

The ifc .410 shotgun upper is a blast! I would not recommend it for anyone who wants a budget AR. I bought one just to say I have one. I absolutely have a blast for it. Im running ATI 15 round magazines for it. I also am running an 80% lower, with a geissele automatics hi-speed national match trigger. I have only gound that ATI & Estate ammo only works in the magazines. The most common .410 shells you can find are too long for the magazines. With the lower, upper, sight, and mags I'm just over 1200 for this rifle.

So, NFA thinking here... shotgun barrel on an AR does sound fun, but I would make sure that when assembles as a shotgun that it meets all of the criteria required to be a legal shotgun. I think if you have an 18”+ barrel you are probably going to be ok in overall length too.
