Actually that's one the things I like about the T68 over some of the other blowback pistols like this, RAP4 has a full parts listing that can be ordered from the website.
The Gen2 T68 and later have a REALLY nice pierce pin block, which outperforms anything else that comes standard except the Phantom pierce pins, of course. This part is only $6 and I've seen it fit on Delta68s, PTXs also, apparently the threads in the pierce pin block are pretty universal as the tube is sized to the hammer and valve. It has a steel pin cast right into the block, then a phantom style face seal like a washer just jams in over it.
The zeus based pistols have a different style block, but that one can be modded for phantom pins easily.
We play Pistol and we encourage the Few despite the discouragement of the Many.
