AICS pattern AR

[Snuby642]

So why has someone not made an aics pattern ar reciver?

 

[GhostFace]

Why? Just for the mags?

 

[Snuby642]

No, for the extra lenght rounds you could use same as for bolt guns.

It would involve changes to recievers, bcg and maybe trigger group.

You could throat barrels longer to take advantage, minor thing.

Same reasons it's done for bolt guns basically.

 

[D̷e̷v̷i̷l̷D̷o̷c̷A̷Z̷]

Becaaaaause no one wants $100 mags when $8 mags work just fine.

 

[Snuby642]

It would be for competition / hunting not for work.

I can't belive a custom firearms manufacturer (not assembler) hadn't done it just for fun.

Probably because it doesn't sound like fun.

 

[Snuby642]

Innovation, kind of like building the extra long magazine. (Extra deep)

Next step, build semi automatic platform for it.

Because you can.

 

[hlee]

Because “proprietary” is a sin that few get away with in the AR world.

 

[Milf Dots]

The OP has a point- why not do it for shits and giggles? I mean- one can buy an inflatable sheep on the internet...

 

[Snuby642]

Why in hell would you want an inflatable sheep?


You can just get Craig's list hookers.

Point is 0.140 thousands more mag room.

I’ve got 2 genuine AI aics 5 round mags, as well as a few magpul aics pattern pmags. The AI mags are not mystical. The clouds don’t part when used. Honestly, they’re a let down for what they cost. They feed worse than the magpul mags. The follower design is a joke played on the entire shooting community. And, they’re a pain in the ass to load- compared to a SR-25 pattern mag. I MUCH prefer to run SR-25 pattern mags in my RPR. They are more reliable than AICS mags, and less prone to allow nose diving rounds. I swear, if you see someone with a mag issue at a PRS event, it’s because of a fucking AICS mag- and mag malfs are embarrassingly common. Maybe AI has it figured out on their chassis, but fuck if anyone else has it figured out. Nope nope nope on aics mags in a rifle that needs to be reliable.

Edit to add… who the fuck wants an AR built around 10 rounds mags?

 

[TonyTheTiger]

Point is 0.140 thousands more mag room.

I would cut the front of my mags if I wanted more length long before I'd want to reinvent the large frame AR wheel. Mind you the large frames are already a parts compatibility nightmare, why add to it?

Bet you have a whole flock

 

[akmike47]

I don't know what the mag length is but wouldn't this just be a Armalite AR-10B mag lower pretty much?

I think it's similar to a AICS with the binder plate going from a 10yo memory.

My buddy had a Larue(I think) 308 SBR that ran those mags.

 

[Snuby642]

Well I didn't limit it to small frame but that's my main deal.

None of it would matter in short range play, but if you want to dig deeper it could open up choices .
The aics existing mags would be fine.

That's nice how about a list for small frame.

Shame it’s not me I guess. A glock of inflatable sheep might be worth something.

What's considered max OAL for the AICS? 2.883"?

no. People really wanting these for the OAL use the versions without binder plates. My MDT mags for example go to 2.960” reliably.

 

[TonyTheTiger]

I just assumed you were talking large frame. What small frame cartridges are you wanting to load to +2.8"?

 

[Snuby642]

PMAG® 10 5.56 AC – AICS Short Action

Reliable, short action AICS-pattern 5.56 magazine

magpul.com

2.39 vs 2.25 with a longer throated barrel run same as any bolt gun.

You could run 90g bullets in that.

 

[2aBaC̶a̶]

No, for the extra lenght rounds you could use same as for bolt guns.

What caliber and length rounds exactly?

 

[hlee]

$40, 10 round mags for a 5.56 AR? GTFO with that.

 

[padom]

For what caliber????

I run KAC and ASC SS large frame mags for 6.5cm....they allow COAL of 2.865" for ASC and my KAC allow 2.87

I dont load 6.5cm rounds even close to this....so there are mags that give you long coal in large frame gasser. I have no reason to need longer coal in my 6.5cm gasser with these mags shooting 140gr 6.5 projectiles...

 

[TonyTheTiger]

2.39 vs 2.25 with a longer throated barrel run same as any bolt gun.

You can get 2.37" by cutting mags.

 

[Snuby642]

Tell me more about cutting mags.

I know I can get + 0.02 with steel which I'm not fond of but that's not going to allow the heavies.

223 is what I fool with the most in gassers but also load 6.5g which could also benifit for some bullets.

I figure any of the small frame cartridges could benifit.

No large frame gassers in my stall.

 

[TonyTheTiger]

Tell me more about cutting mags.

Pretty much exactly what it sounds like.

This combined with a relief cut in the magwell will get you to 2.41" ish. Those are 75ELD's at about 2900, a pretty big step up in performance from average mag length loads, but not big enough to re work the entire AR platform for.

Holy shitballs, what’s all over that mag and rounds?

 

[TonyTheTiger]

Dust from one of my kids filing on wood projects in my man cave.

 

[hlee]

I tried a cut mag in my 308 and the cartridges don’t feed for shit. Maybe I need to do more deburring, but a mag that fed fine before the cut (at 2.80 OAL) doesn’t feed at 2.88. Maybe I should do more investigation. There is a REAL difference in group size from 2.80 to 2.88 with this load…

kids

The struggle is real…

 

[TonyTheTiger]

The struggle is real…

It is. But I can't be mad at them for always making things with their hands like the human kids used to in the 90's. The newfangled robot kids these days are boring.

Idle hands are the devils playground. I like to see my kids stay busy as well

 

[Austan]

I thought you might be talking about the stock portion which I played around with on the design side for a day. I thought about putting in another day on it and 3d printing it to play with but it's way down the priority list.

 

[Snuby642]

That's innovation can you scrape up enough room for an aics mag without changing geometry for upper fit ?
