For everyone's infomation, I ordered one of the titanium fire pistons and it arrived in just a few days. Very quick service. Esteban was very helpful in answering my questions before ordering too. A fire piston and one of Esteban's Exo Tubes was bought. Both items are machined VERY well. As a bonus, the fire piston fits inside the exo tube like a glove. Tightening down the exo tube's cap onto it's o-ring seal keeps the fire piston from rattling around inside the exo tube. A perfect fit.
Again, I am very pleased with Esteban's work and product and plan on recommending it to others. I haven't had time to try the fire piston yest, but am looking forward to practicing to get the technique down. I figure it'd take practice to get any fire piston to work, and at least with this titanium one, there isn't the concern of it breaking. It'll last a lifetime!
Thanks Esteban! Hey, expand your product line to include more titanium gadgets and gizmos too!
