The MGI Survival Package — Four Popular Calibers in One System

MG Industries Survival Package MARCK-15 rifle

The Hydra – One Weapon, Multiple Configurations

Are you a casual shooter, serious competitor or firearm collector? How about someone who takes survival and preparation seriously? Regardless of the type of shooter you are, MG Industries has, quite possibly the last, platform you’ll ever need (want is quite another topic).

In recent years, manufacturers have been increasingly offering new designs capable of being easily converted to shoot a variety of calibers. Arguably, enthusiasm from the survivalist community has led the effort to spread the word and garner support for these designs. However, with the stagnant economy and shooters’ desires for versatility, MGI’s “Hydra” platform has carved a niche that distinguishes its design apart from what we commonly perceive in an AR-15.

MG Industries Survival Package combines four calibers—popular with casual shooters and survivalists alike—in one easy to use and easy to transport package. The Survival Package is professionally laid out in an ultra tough, lockable long gun case with strategically positioned foam cutouts to securely hold each piece of equipment for quick assembly and stowage.

MGI’s Survival Package is built on the MARCK-15 “Hydra” platform. The base system starts from a 9mm with a modular lower receiver, 9mm magazine well, CQB-D upper receiver, 16-inch bull barrel and 9mm Colt-style bolt. From there, the package is expanded to include three of the most popular calibers (for military and survival) on the market: 5.56 NATO, 7.62×39 and .300 Blackout.

MG Industries Survival Package combines four calibers—popular with casual shooters and survivalists alike—in one easy to use and easy to transport package.
The 5.56 NATO conversion package includes the 5.56 barrel, complete bolt carrier group and the AR magwell. The 7.62×39, or AK-47 conversion kit, comes with a 7.62×39 barrel, MGI’s enhanced 7.62×39 bolt and firing pin installed in MGI’s modified bolt carrier and AK-47 magwell. A complete .300 Blackout barrel is also included and ready for use.

According to MGI, the MARCK-15 Hydra is the only truly modular rifle that can convert into multiple calibers in seconds. Designed by an industry innovator and veteran, the MARCK-15 may well be the last rifle you will ever need. However, should you feel the need to add additional calibers, the MARCK-15 Hydra is available in most, if not all, of your favorites.

The MARCK-15’s unique design handles all three methods of operation: blowback, impingement and gas. For those who blessed few prepared to go full auto, the quick barrel-change capability will keep you rock and rollin’. When one barrel gets too warm, you can swap out a spare in less than 30 seconds and resume sending lead down range.

The MARCK-15 would certainly fit into most any home defense, survivalist or casual shooter’s collection and the variety of calibers offered has a lot of appeal and application. Personally, I could see a MARCK-15 in .450 Thumper sneaking into the gun safe one of these days. I don’t really know why, but I love the thought.

How would you configure the MARCK-15? Would you go with the Survival Package or is .450 Thumper more your style? Tell us in the comment section.

  1. What about optics?. Changing caliber is great and all but the one optic on the top is not gonna be accurate for all the calibers. Seems like a waste. I’ll stick with my AR and different uppers with the optics configured for that caliber

  2. I understand the one gun concept but it still is a bit high for the average shooter. As noted all the calibers can be purchased separately and still have money for ammo.

  3. These are awesome rifles and the interchangeable platform is like no other, While I agree you can buy an AR, AK and 9mm for the price of one of these, I know they are working on several calibers that are not available in an AR platform rifle, the 30-06 is one example. As far as the SBR idea, you can own a registered SBR in several calibers.
    Everything I have seen on these rifles has been positive and that works for me. They do offer different several different combinations to choose from to make it more affordable.

  4. Sounds interesting at first, but for $2250, I can get an AR-15, an AK-47, and a 9mm carbine, have 3 separate guns that can be used at the same time by 3 different people, if SHTF, and still have money left over.

    1. I don’t think you can get all three for $3350 these days, but I think you miss the point.

      With this kit, you only have to tote one case that has everything in it for 3-4 guns, not 4 separate cases.

      Another important factor that someone brought up is the SBR angle. You could have short barrels for all of your rifles, but only need one SBR registered lower.

    2. Yes, I can get them all. I’ve seen a couple different prices thrown around now. I checked their website and it said the survival package contains a9mm HYDRA rifle with a Colt style magazine. A CVP-AR556 which is a 5.56 barrel, complete bolt carrier group and the AR mag well, the CVP-AK47 which is the 7.62 x 39 barrel, MGI’s enhanced 7.62 x 39 bolt and firing pin for $2799. The starter kit contains the MARCK-15-9SMG-C which is the 9mm rifle that takes Colt style magazines, the CVP-AR556 which is a 5.56 barrel, complete bolt carrier group and the AR mag well and the CVP-.22LR which is a .22 LR drop-in kit for $2250. I don’t know the difference in the 2 9mm rifles. Maybe just the name. Either way, it’s just too much money for me. I would much rather have the complete guns and the extra cash.

  5. I have mixed feelings about MGI.

    I own an MGI rifle that I bought piece by piece, rather than as a complete firearm. I originally just bought the modular lower receiver to register as an SBR, thinking that if it became more difficult to get Form 4s done some time in the future (see, e.g., ATF 41P) I would already have the registered SBR, but in the most reconfigurable mode possible. I asked a local NFA dealer to register an MGI lower as an SBR, and then I bought it from him on a Form 4.

    After buying the AK mag well, I negotiated a deal with a buddy to buy his 7.62x39mm upper, but upon further investigation realized that using it with the MGI lower and AK mag well would require substantial modifications to the upper receiver and bolt carrier. Then I bought an MGI Hydra upper and their custom bolt carrier designed to work with AK magazines. When the upper arrived, it would not readily mate with my MGI lower. The upper receiver stud ultimately had to be filed down in order to clear the interior surfaces of the lower (since the lower is the registered NFA item I chose to modify the more readily replaceable part).

    The internal dimensions on the AK mag well are another potential problem. Since the mag well is aluminum, I thought I would go with Magpul’s new polymer AK magazines to reduce wear on the mag well. Wrong. They would not fit without a good bit of modification with my dremel. I appreciate the ergonomic advantages of the way AK mags go in and out of MGI’s mag well, so I ended up just buying steel AK mags. They work well, and magazine insertion and extraction are much easier than with an AK.

    So then I went to the range. It turns out that the standard hammer spring from the lower parts kit I installed did not have enough oomph to touch off the hard primers in Russian steel cased cartridges. After installation of a stronger hammer spring, I managed to get the 7.62x39mm setup running.

    I also bought the AR mag well from MGI. It is compatible with standard GI magazines and the Magpul PMAG. The only problem with the AR mag well is that the way that the lower receiver modules link up leaves lots of play in the lower. Instead of an upper and lower rattling around on their pins, you have an upper and two lower receiver modules rattling around, with that third joint in the middle of the lower adding significant play to the whole contraption.

    Finally, MGI’s manufacturing is, to my admittedly unlearned eye, substandard. Sharp edges, burrs, and tool marks abound. For the very substantial price for these components, I expect them to fit together and to not cut me. The example of MGI’s work that I am in possession of is not up to that standard.

    With that said, it is a neat concept. I wish the execution had been better.

    1. You should have contacted MGI and let them take care of any fitting problems, Im curious as to why you would change the lower parts kit? The factory ones work very well, especially with their systems, and MGI staff are awesome to deal with, they stand behind their products 100%!

    2. As I said in my comment, “I originally just bought the modular lower receiver…”

      I was not replacing anything by installing a lower parts kit in a stripped lower.

      It isn’t simply a matter of fit. The finishing work on these components was very poor. As I said, they anodized parts and mailed them out without even properly deburring them.

      I’m not interested in bending over backwards to cover for a company that is doing shoddy work. If their product is poorly made, people should know about it. They can improve their QC or keep getting critical reviews.

  6. I forgot to mention; I purchased MGI’s basic riffle in 55.6 in a flat top version around 2 years ago. I paid $1250.00 for mine when a comparable AR would run you at least twice that much. It was my first AR and I was intrigued with the whole “modular platform” concept. I purchased a CCMG 22lr conversion kit from CTD last year and it works flawlessly. It was also much cheaper than going through MGI. The folks at MGI are great to deal with, I’ve called numerous times with “dumb” questions for which they’ve always taken the time to help and been very patient. The ONLY and biggest problem I’ve had with MGI is Them being able to “deliver” on the stuff they promote in a timely fasion. It seems like they promoted their sytem with out the production or testing to back it up? For example, I was put on a waiting list for their new (at that time) 308 conversion kit early last year with an expected build/delivery time “sometime that fall”, it never happened, no call. I contacted them they said they’re having production issues and are behind so “sometime in winter for sure”. Still nothing and no word? I was hoping to use the 308 conversion for a hog hunt in the spring So I contacted them again, I was informed they’re not offering the 308 at this time, it’s back on the “drawing board” with some design issues? I inquired about the belt-fed conversion they promoted when I first purchased mine. I was told the company that they contracted to supply them was bought out and would no longer supply them. There are other caliber options that were once promoted but no longer offered. My feeling is like many companies that come up with a good product/concept but possibly don’t think through the marketing and or production side of things?
    The rifle is a decent no-frills AR at a good price.BUT with the ability to easily convert to many other cal’s and operating systems using mostly “off the shelf” parts. Designed and built by one of the inovative “old timers” in the industry, Mack Gwinn Jr.
    To answer earlier comments/questions They just started offering “Packages”. which is a cool idea
    They offer one called their “Starter Package” which is their basic rifle in 9mm, with the 5.56/223, and 22lr conversion parts included all in a really nice hard case for $2250.00. I just wish they had offered that when I bought mine. (sorry for being so long winded)

  7. I’m now planning to get the components for the 450 Bushmaster “Thumper” for the “big critters” i.e. hog and brown bear or moose, and the 6.5 grendal to be able to “reach out and touch” the long range stuff.

  8. I agree that .22 lr is a better choice than the .300 Blackout. The 7.62 is heavy duty enough for most game. Even though the .22 lr is a little hard to come by right now it’s not that hard to get a hold of (and at an affordable price) if you will just do a simple search for .22 lr in stock.

  9. looks like a good setup except,,,300 blkout is not a readily avail. crtg. 22 lr would seem to be a better choice

  10. I was wondering what the suggested etail price was on this unit as shown, I saw another comment stating that is was reasonable considering the amount of gear that it comes with, but saw nothing of price, anybody know? I would like to know at least so I can tell my friends about it, thanks.

  11. Looks like a very cool system.

    The only things missing is a .22 LR conversion kit and maybe a suppressor.

    The price isn’t bad considering all that is included.
