The MAC35. Is it the Next “big” thing in airguns?

I have been waiting for months to get my hands on the new Mac 35 from Inovairtech, LLC.  I spoke with inventor and President David Priestley a while back, and even met with him and Paul Baxter some months ago here in my studio. It’s been a long, painful wait, but the day finally arrived and I received the very first pre-production MAC35 to make it off the assembly line.

You have to see it to really believe it

The MAC35 is the culmination of 20 years of airgunning and the creation of David Priestley. David wanted some very specific things out of an airgun and not finding it anywhere in the market, he chose to just build it himself. Long story short, he and his longtime friend and associate Paul Baxter created Inovairtech LLC. (www.inovairtech.com) to bring his new invention to the airgunning public.

When you see the MAC35 in photos, you just really don’t get the scale of it all. This rifle is 51.5″ long and weighs 14 pounds with my Hawke Sidewinder 30 mounted on it. It’s modeled after the old single shot Barrett M99 .50 cal sniper rifle. It’s simply impressive to look at and just take it all in.

Airgunning perfected?

I’ve heard this phrase a lot from Paul and David. Is the MAC35 airgunning perfected? It’s a little early for that claim to be confirmed. Is it a significant shift in thinking about how pressurized air can be used to hurl a large caliber pellet or bullet at a target? Most definitely! While there were some products in the past that used self-contained, pressurized cartridges, this system does it very differently with extreme predictability, reliability and flexibility.

It all starts with the cartridge

The heart of the MAC35 is the patented cartridge. This revolutionary cartridge can be filled up to 4500 psi (Safety pressure tested to 20,000 psi) and deliver approximately 120 foot pounds of energy from a 9mm bullet or pellet.

MAC = Magnum Air Cartridge.  This one is chambered for .357/9mm and can produce up to 120 FPE.

Filling the cartridges couldn’t be easier. Inovairtech, LLC. provides a 3/8 NTP quick disconnect fill connector that can be fitted with a foster quick disconnect male end and attached to any PCP fill system. I’ve set up a very simple fill adapter using a standard aluminum K-Valve paintball fill kit with female QD. This is super-efficient and you only loose a tiny amount of air when you bleed off the adapter to remove the cartridge. To provide an efficient, safe, turnkey solution, Inovairtech, LLC. will be offering a complete fill assembly in the near future. The volume of each cartridge is approximately 10cc, so you’re going to get a lot of fills from your standard HPA tank. There’s very little variation in velocity with a +/- of 100 to 200 psi, so don’t be concerned about filling each cartridge to exactly the same fill pressure.

Filling the MAC Cartridges is very simple.  Just slowly open the valve till you reach your desired pressure, close the valve, bleed the system, and you're ready to go.

Once the cartridge is charged, you just need to select what type of ammo you’re going to put into the front of the cartridge.   So far I’ve tried several ammo choices from flat nose, round nose, round ball, hollow point, wadcutter, sem-wadcutter, and my favorite, the JSB .357 match grade pellets. Accuracy and range will be determined by pressure and ammunition. The versatility of MAC35 allows the shooter to match ammunition at various pressures to achieve the right combination for hunting or serious target shooting.

Loading and firing

This is where things get really, really fun. Loading the MAC35 is just like loading a single shot, bolt action center fire rifle. You pull the bolt back, load your cartridge, close the bolt, and then fire when ready. The weight and balance of the MAC35 lends itself to bench shooting or shooting from the prone position. Fortunately Inovairtech, LLC. includes a Bipod as standard equipment.   It’s extremely comfortable and enjoyable to shoot.

Loading the MAC will be very familiar to anyone that's ever operated a bolt action rifle.

High quality components and made in the USA

One point that I’ve not really talked about yet, is the overall component quality. David is a perfectionist. One of the reasons that it’s taken a little longer to get the first MAC35’s out the door was that the initial widely accepted “best barrel” on the market, just wasn’t good enough for him. So, he commissioned custom, match grade barrels built to his exact specifications. The receivers are all 6061-T6 aircraft grade aluminum, and the bolts are stainless steel. The trigger components will be fully adjustable and made from hardened steel.   The rear stock uses a standard M4 style and is completely interchangeable with the compatible variants out on the market.   What’s most impressive to me is that this gun and the components will be made and assembled here in the USA. I’m very happy to be a part of this great project.

Inovairtech, LLC. – Looking forward to the future

So when can you get your hands on one of these? Current lead time is about 45 days. You can go to www.inovairtech.com to get more information on pricing and options. This is just the beginning. There are so many ways they can utilize this technology to revolutionize how we think about airguns. It’s taken me a few months of wrapping myself around the concept and many discussions with David and Paul about how I have to see this differently from my traditional Big Bore PCP airgun. I get it now. Now that I have one here in the shop and have spent time with it out at the range. It all makes a lot of sense.
