So recently I learned that Wolf is importing T91 uppers from Taiwan. They were $600 at launch, now they’re like $450 with a charging handle and BCG. A hell of a lot less than any other piston uppers and they seem to have a couple of decades of real-world use to back up the platform, any of you guys have experience with them?
Agreed. This is a solution looking for a problem. If the AR needed an op rod, Stoner would have given it one. Technically I don’t think you can retrofit a DI gun with another op system and expect it to work. One of those sounds great in theory sucks in reality things.
If they ran they probably wouldn’t be sold off as surplus right now. I would bet the uppers going back on all those lowers (if not destroyed) would be DI systems.
