1. In a Percentage of factory Izzys, the Valve Chamber is corroded and the guns will not seal.
If the corrosion is not there initially, Without proper lubrication it can happen anytime.
And the leaker will want our upgrade
(Compressing Air will always leave moisture in the mild steel chamber).
Mac1 replaces this chamber with Non-Magnetic and Non-Corroding Stainless Steel.
(Tiny metal debris can collect in the factory airguns with regular steel chambers)
Better Power: Our chamber volume is slightly less, so each charge has slightly elevated pressure to give slightly better power.
2. We strip out the Russian Seals, and replace them with 90 durometer American seals that are harder and more durable.
We have been doing this for 5 years since the first Izzy 46’s appeared.
The Result: No Failures have occurred on any IZZY 46 Airgun Mac1 has upgraded. NADA
We do other good things too…..but let us keep some of our Trade Craft a Secret.
What you get is the most “Bullet Proof” 46m Pistol available. Period.
We are always building into the Mac1 IZZY the ultimate accuracy, consistency and durability.
