Caliber swap on Avenger

It would be the barrel, magazine, and caliber specific probe. No need to exchange regulators. If it cost more than $120 shipped then you might be cheaper off buying a $100 ATI Nova Liberty in AS-IS condition that were stockpiled defective warranty swap outs likely due to leak and lack of replacement parts (namely the most important part the Avenger will eventually need replacing that has no part number) to repair them in house.

Don't try to power a light bulb using a potato.

Hence the reason I didn't buy into that product.
