Inovairtech - MAC35

[Inovairtech]

Hi All

We currently have several products in production and on the design board, however our first product launch (due late Spring 2014) is the MAC35

A high power full-bore air-gunning in .357 (9mm) calibre without being tied to your refill tank.

Unlike most current PCP full-bore air rifles that are only good for a few shots before refilling, the MAC system lets you load up as many cartridges as you plan to use and then you are free to enjoy the simple pleasure of shooting and not worry about how many shots are remaining in your guns integral air tank.

The platform resembles a typical long range sniper rifle, built with integral picatinny rails for easy addition of accessories, such as scopes, bi-pods, lamps, laser sighting systems etc.  (The Inovairtech on-line shop will offer all the shooter can ask for in terms of accessories for your MAC35).

Function - Just imagine the function of a traditional bolt-action firearm rifle and there is no more to say about how it works.

The action is a crisp bolt-action single shot design, enabling smooth, precise shooting at typical air gun ranges. The single stage trigger has a 4lb pull, making the whole shooting experience an absolute pleasure.

The MAC .35 has a fired-cartridge ejection system to remove used cartridges effectively, ready to receive a fresh charged and loaded magnum air cartridge. The bolt operates in the same manner as a center-fire rifle, making it totally intuitive for even the novice shooter.

As the whole loading, firing, ejection and re-loading with the magnum air cartridge totally emulates a traditional center fire cartridge - it is great news for cheap training and shooting practice - all the feel of the real thing, at a fraction of the cost, just a little compressed air and a fresh bullet / pellet, refilling the air cartridge with air prior to re-use.

The MAC .35 frame is constructed from light-weight aircraft grade aluminium, with a 28" (71mm) Lothar Walther steel barrel and key components constructed from stainless steel. This makes the MAC .35 rugged and yet lightweight, tipping the scales at 4Kgs (8.5lbs), even with the 'bull' 22mm barrel and barrel 'muzzle protector'. External finish is 'Cerakote' for durability and purchasers can suggest customs colours from the Cerakote range to bespoke their MAC35 when ordering (Additional cost applies)

The Inovairtech MAC .35 is designed to handle cast soft lead bullets up to 145 grains or commercially available 9mm pellets of typically around 65-80 grains weight and launch them at speeds of up to 800 feet per second.

Best performance is achieved with bullets in the 105 - 130gr weight range, which maximize the muzzle (Kinetic) energy of the airgun and do so without a loud report.

The MAC 35 can handle bullets up to 190gr in weight offering high muzzle (Kinetic) energy and low noise, in fact the use of heavy weight bullets significantly reduces the noise on firing to a level similar to a spring powered airgun, as the long barrel facilitates conversion of more of the high pressure air to muzzle energy.

ALL test ammunition, (from 67-190 grains) produce report noise SIGNIFICANTLY LESS than that of a conventional PCP airgun of similar power.

Modern engineering of a totally new concept brings the dream of shooting realism at a realistic price.

Other projects in the pipeline include:

-MAC35P - Everything the MAC35 offers but in a pistol!!
-MAC30 .30 cal
-MAC25 .250 cal
-MAC41 0.410 cal shotgun

We will also be offering optional extras for the MAC35 with a magazine or feed belt.

Hi John

Sorry for the confusing post, the website is up and running with pictures and video link BUT 1) the posting didn't allow external links and 2) it will be updated significantly in the next week or so.

I'm interested to see how the air cartridge is released. In theory each cart would have the same exact amount of air in it, so no shot curve. Interesting design and I can't say i've seen it before. Any chance of an explanation of how the firing mechanism works?

[Rescue35]

I was wondering when someone would think of this. Looking forward to seeing more

Same basic idea as the Brocock cartridge, but brought into the modern era.... https://www.pyramydair.com/blog/2006/01/brocock-air-cartridges/

I certainly like the concept, the interesting part hasn't been given, and that is the performance.... You mention bullets from 65-145 gr. and velocities of "up to 800 fps", so logically that would lead me to assume that would be with the 65 gr. bullet, giving an energy of about 92 FPE.... You also state that the optimal bullet weight is in the range of 105-130 gr. to optimize the FPE (logical), but without stating what that achieved maximum FPE is.... I hope you will update this thread as soon as those figures become available....

That looks like a great list of future products, and I wish you all the best in the development and market of a unique product that may well find a niche in the airgunning community....

And please say that you have selected a twist that is optimal to the bullet length!

It's good that you have selected 9mm.  AZ is now legal to take a lot of game with .3 or higher ammo.

Actually, I am looking for a 9mm this year!

From there website.

*1 - Test data obtained in real tests carried out during November and December 2013.

Ammunition used:

1) 67gr Round Balls, 2) 77.62gr JSP Pellets, 3) 105gr soft cast semi-wadcutters, 4) 115gr Soft cast Round nosed bullets, 5) 127gr, Soft cast Flat nose bullets, 6) 190gr Soft cast Round nosed bullets.

ACTUAL Muzzle velocities achieved using the test ammo were 500 f.p.s. to 750 f.p.s. with resultant muzzle energy in the range of 85-125 FPE. (Ft/Lbs). We are still testing ammunition to decide which works best in our rifles and so can make recommendations to our customers as to the best ways to extract the best performance from your chosen Inovairtech weapon.


Darn, why couldn't it be at least  ~200 FPE.  The thing looks like a 50 cal BMG , but isn't any more powerful than an Evanix at max power.

Sounds like they need to add to the staff. Like maybe Bob and Lloyd to name a couple.

And plenty of field testers that can give ideas for improvement. I'm not going to start throwing names out because I'd certainly miss a few most EXCELLENT technicians!!!
But GTA sure has some talent that could work magic with this platform.

[Jeremy1982]

love the idea but I want something with a lil umpppp!I get 245 fpe out my recluse

[rsterne]

I see two methods to get more power.... use more than 4250 psi.... or make larger cartridges.... I would assume that all the air in the cartridge is dumped on each shot (but I could be very wrong about that).... leaving the cartridge empty after firing.... If this is the case, and assuming that the roughly 125 FPE on the website is the current limit, then making more air available for the shot would be the only alternative I can see....

If only a small portion of the air is released during the shot, then changing that volume would, of course change the power.... Ultimately, the FPE will be basically proportional to the quantity of air released during the shot....

My 2 problems with this style gun is just that, its an AR look alike. It may be required due to its design but id love to see a more conventional, say Rem 700. The other concern is im pretty sure this style of gun would be regulated as just that, a powder burner with its self contained cartridge.  Still I look forward to learning more about them.

[Shadowtester]

Another way to increase the power would be to change the gas used.

Another way to increase the power would be to change the gas used.

Other than a combination of fine diesel-oil vapour in oxygen (which would do the trick)  ,  the only gas that would do better is probably helium, or hydrogen. Hydrogen is out the window for the same reason as the diesel-oil - so you're left with helium. Cartridges might leak, and would be pricey fills...

Looks more like a Barrett to me.

Someone has asked this before about this design, but I'll ask again in case the original poster knows...

What about dirt etc on the ejected cartridges? Is there any special wash or treatment that has to be done before re-using one of them after ejecting - so that fine dirt doesn't cause leaks in the HPA system?

Yes helium was the gas I was referring to I did not say it would be without some problems or that it would be cheap. I just stated that another gas would increase power I do not think it would be the best way to increase power just a possible way to increase power.

[rsterne]

Yes, using Helium would increase the power of any PCP, so you're back to the same comparison, as many current .357s are over 200 FPE (on air)....

Here in the U.S., the federal government defines firearms as having (1) "Fixed ammunition" from which the projectile is propelled by an (2) "Explosive". Fixed ammunition is defined as the Bullet, Case, Primer and Powder ("Explosive") as a unitized cartridge. Explosives are defined as "a solid or liquid material, or a mixture of materials, which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to its surroundings".

Muzzle loaders are not firearms under US federal law, only cartridge firearms. Air guns are not within the scope of the GCA 1968.

Interestingly, Nevada made no legal distinction between air guns and firearms until about 1992: up to that point, they were the same. The bottom line is this: Read your laws and know your laws.

[rsterne]

So then, this is not a firearm under Federal Law in the USA as there is no "Explosive" as defined in the law....
