anybody heard about this?:confused:

http://www.mgimilitary.com/

supposed to be easy as, replace the barrel and barrel carrier. then change the mag reciever to whatever cal your shooting so that the right mag can be used with the right cartridge, AK mags for AK cal., .45 ACP grease gun mags and 9x19 using sten mags(glock, uzi and colt) can be used. they are all used normally and unmodified.:D

i have pretty well decided about the setup for my first AR. i am just curious of whether anybody knows anything about this system or has used it. it seems to be good in theory, but theory world and real world have always been a bit different at the least!

I have seen one made by Cobb Arms, but not by that company. Cobb claims to have made the first multi-caliber AR-15.

Looks like a really high priced AR.

My FFL buddy sold a Cobb .308 (uses G3 mags) to a customer and the customer has had nothing but problems with it. I was copied on all correspondence about the problem. As it turned out, there were gas issues with the Cobb. It was blowing gas rings left and right. It has already been back to Cobb twice. One of the tops dogs over at Cobb told the upset customer "If I had to pay my gunsmith's $12/hr, the price of the rifle would go through the roof!" That's just pathetic. I don't want to pay that much money for a rifle that turns out to be poor quality b/c the gunsmiths don't even make $25K a year. The old adage of "you get what you pay for" also applies to companies and their employees.

With that being said, if the MGI works and has decent support and QC in place, it seems it would be a viable option for a fully modular rifle.

Overpriced mall ninja tacticool junk. Ooh look, it's MODULAR! I can change calibers on my AR by only changing these 6 pieces (that cost as much as a complete AR). And that solves what problem exactly?

Why, the simple problem that you can't take a 5.56 AR and make it a .308! :mrgreen: I agree with ya though, I'd rather go out and buy another rifle, but I'm not going to argue with more black rifles being on the market, whether or not I see them as financially wise investments. :shock:

Even if I saw that as a problem (which I don't since I have an FAL), this rifle doesn't solve it. It won't convert to 308.

thanks for the insights, i appreciate them. i didnt really have a lot of hope going that way i just figured i'd ask, instead of not getting it and it being worth it. my only really big issue is the round size, 5.56, .203, 7.62, .308? i still cant awys remember can .203 fire a 5.56 or vise versa and does the same apply to 7.62 and .308?

im gonna go and just get some decent little package deal, 5.56, probably in a M-4 type setup, but may go a little bigger for a little more range. but something basic, with iron sights than can fold down, flat top, eotech or aimpoint( not mall ninja just cause i can, it looks nice, and most imprtantly they seem to workk well, plus i just like to be ready. our local nuc plant is worst in the U.S. for security- i dont think anything would happen, but you just dont know ) decent sling, a few extra mags, a light/laser ( have it on my XD and it helps a lot when shooting just to "see my flinch" plus the light was a fore sure and so why not have the laser. it does have a small amount of "cool" factor) maybe a vertical forend grip and most importantly a really good case for it and my xd, maybe even the shotty as its pistol grip, but i want a really good box.

sorry for the rant i just finally think i have the idea!

The Cobb MCR300 will change from 5.56 to .308. If that's a problem needing solving, then a fully modular system like the MCR solves it.

Oija, you might want to rethink the laser option. With a red dot sight like an Aimpoint, you already have a red dot projected on the target, one that the target can't see. If you add a laser sighting system, you'll see the red dot from the Aimpoint and the red dot from the laser sight. That seems to be redundant. I'd say go with a good light setup, but skip the laser if you are plan on using an Aimpoint or Eotech.
G
please read thru and see questions at bottom, thank you.

yeah thanks, i didnt even think about the two "spots" in that config. so a good independant light setup along with the optics, eotech/aimpoint would be plenty sufficient.with the health problems i have i cant really "hit" the wall with a foot or "bump" into anything, have to be super careful and be able to see. especially that im trying to get back on my feet more after five years of not doing much but throwing up and having constant feelings that my feet were on fire from the inside out among other great feelings. so a light is a no brainer for me, a peice of the "always within reach gear" along with a pair of backup CR123 (the lights holster comes w/ a place to carry them), my XD, two knives(Benchmade infedel OTF for weak side defense and Benchmade Stryker 9100 for all the work) and depending on where we are going, and what time, up to two extra clips and my X2L. so i need a light on the rifle, a light on my belt, a light on my pistol and a light in just about every room in the house. that way if the lights go out i know exactly where to go to find a light. they consist of 5 "tac" lights-nextorch T6A...cheap and made well yet not a surefire, X2L on the XD, and a "3 D" maglite and minimag both LED-with spares and xtra Xenon for the Mag, everything else is Xenon. might also get something for the mossburg. trying to get what i can of what might be banned this time next year or the year after. doubt it'll happen, but not if these shooting dont stop. or a CCW holder takes one down that had a fully auto AK or something! thats the way it should happen, yet even if it did the public would likely never hear about that(other than the obligatory " the civilian that stopped the attack was permitted to carry a weapon concealed" that happens as they transition to the next story, and you never hear about it again. i was amazed once i started listening for the status of the true hero in that scenario because the're almost always is none.

wow i just totally ranted on...sorry. man that really is long, really sorry.

my only real questions left are kinda dumb, but thats why we are all here, well why im here anyhow.

1. caliber compatability. will a 5.56 rifle fire (Safely) a .203 cartridge or is the oppisite true? same question with 7.62 and .308.

For longer range does the smaller cartridge have better accuracy, and is faster with CQC?

2. O.K. i know this is stupid but i want to make sure i know the real answer. what makes a "carbine" a "carbine" vs an "assault rifle", man i feel it coming...

Ouija,

I feel your pain. I had to do a lot of looking and asking before building my M4.

My recommendation: do not try to build the M4 as a be all, end all solution. Keep it simple and configure it to your needs. If you want long range effectiveness, build it like a National Match or Varminter, if you want CQB, M4 configuration with light weight barrel is awesome. Medium range, 3 gun match or all arounder, 16" midlength or dissipator handguard.
I initially had a light, but took it off and put it on my Mossy 500 for HD (I won't be clearing caves anytime soon). The grip bi-pod is mainly a tool for zeroing / target shooting, but I would prefer a shorty foregrip or GASP no foregrip at all. I like the Eotech, but I need to same up some cash for that, so currently, I'm usuing an Aimpoint clone (not bad for $50 copy)
My AR is mainly for SHTF and paper punching (using the Ciener .22 LR conversion)

I'll do my best to answer your 2 questions, but I'm sure that others will chime in with more experience and knowledge than I.

1. The 5.56 NATO is compatible with the .223 Remington. But usually not the other way around. The .223 has tighter tolerances (so feeding 5.56 might be finicky) and the 5.56 is designed for higher pressures. I've read that the Wylde chambering is somewhere between the two (ie: for accuracy) but RRA has a better description than I can explain.
Depends on the type of 7.62 round... the 7.62x39 is the AK/SKS round and the 7.62x51 is the NATO round that is very similar to the .308. I don't know enough about the similiarities or differences of the 7.62 NATO vs .308 to comment intelligently, so I'll shut my yap. With everything being equal, yes the shorter cartridge length ammo are more accurate but that's like saying a Suburban is faster than a Lotus Elise because it's got more HP... many other factors that go into that equation.

2. In generalities, carbine = assault rifle. I'm sure that others will have other opinions and cite historical reasons why they might be different. Carbines were generally issued to personnel not directly using the rifle for their MOS/jobs, but needed something with more reach than a hand gun. Artillery crews and tankers are prime examples. The term "assault rifle" is relatively new in the nomenclature of weapons, ie: getting more and more use as a term with the introduction of the M-16. Since it used a varmint round and didn't have the 1000 yrd. sighting / terminal energy as the prior "battle rifles" (M1 Garand, M-14) the term "assault rifle" became the de-facto name, among other obvious and less obvious reasons.

I'm also a noob, so if others know better, please share your knowledge.

thanks thats what i figures about the carbine issue. just wanted to make sure.

im not wanting a bipod just a vertical forgrip.

i dont expect to have a be all end all. im planning on buying at least one more AR this year, along with many other things they may ban. already primed the wife for the $$. she gets to have the floors done and i get some guns, works for me. so anyhow i dont plan to have any one weapon that will be the "one". i'm going to try "layering" the ranges of our weapons. hand guns, shotty w/different loads, the AR out to around 200-300 and eventually a "varmit gun", and we have some good lookin rabbits, squirl and other varmit around the state. also like a mini uzi or something like that, just to have.

my mossy is a 500 too. pistol grip with a barrel shroud.

i want my AR to be a SHTF rifle. so thats why i will likely have and eotech or aimpoint-the eotech is my first choice.

how much do the .22 conversions cost?

AND FINALLY.... so if its chambered for the 5.56 it can shoot .203 ? if its chambered for .203 then no 5.56?

thanks the help has me to a point that i just may go this week and pickup the weapon.

The ciener kit from cheaper than dirt costs ~139.
PRetty accurate... would make a good squirrel hunter if zeroed properly.

And yes, 5.56 will shoot .223, but .223 will have more issues with the 5.56.

Cheers,

For the price of an MCR300 I can buy an M4gery, an AR-15, and an M1A. Along with ammo and accessories.

A modular rifle is an interesting technical achievement, but simply has no practical application.

yeah, the models that can be changed out for cal., are really just a "coolness" factor i suppose. pretty well given up on that, id rather get two AR's and learn the weapon thru and thru, that way if one goes down for whatever reason in some SHTF scenario i have an entire backup set of parts that just happen to be put together and ready to fire.

basically looking at the M-4 setup, AR-15, and after two, an AR and M-4, then gonna look at something smaller and cheaper, but not "cheap".

then fix up the mossy w/ a light, foldable stock, optics for quick target aquisition(maybe a laser, or something along line of an eotech/aimpoint- not looked at this yet so i might not be the right option-we'll see) and a better side saddle(metal instead of polymer) and finally a good sling.

i will likely start another thread about this but thought i'd fish here for a bit... anyone use any Kifaru gear? they do a lot of packs and things like that. they seem to have great gear. i watched the discovery channel about how they made the "Planet Earth" series, pretty cool. anyhow they were using Kifaru gear, at least some of it anyhow. check it out here http://www.kifaru.net/ and see what you think. im sure its not cheap but its U.S.A. made and has a great gaurantee.

THANKS AGAIN FOR ALL THE HELP! i went from i have no idea what i want to im pretty sure i know what i want and i now know who makes good AR's and some of the features and furniture i would like. thanks.

Agreed, but for some people, price isn't the all-important factor. Some people just "got to have" that $5000 bolt action for 1000 yard competitions, or the $2000 SIG 556 (with an MSRP of $1300) because nothing else will scratch that itch they have. Those types don't want the cheaper alternative with a proven track record, they want to be the only ones with the newest, most expensive toy. That's who these companies are marketing to, not the reasonable folks among us! ;) Remember what they say about a fool and his money...
