I thought of putting this in Custom Projects, but I feel more 'pistol' people will see it here.
Well at the Monster Game, my friend Kenzo picked himself up a Delta68 Pistol in(of course) BLUE! Kenzo is a member of the Hell Survivors Mercenaries and occasionally takes the field with his powder coated blue PGP2K when he's not using his Blue Ego.
I offered to 'fix' it up for him and he foolishly accepted
.
The only real drawback to the Delta68 is the pierce pin system. It uses a collar o-ring that seals around the neck of the 12gram. This doesn't always work with crosman co2s and though it works perfect with Brass Eagle brand 12grams, they vary in length so much that the lever changer often leaks! Other than this problem they are as good as any pistol out and already have a lever changer and dropout for the 12ies! So I had to figure out a way to convert the gun to use CCI Phantom pierce pins, which seal to the face of the 12gram, this means they work perfect with any brand of co2 and are more forgiving of variations in co2 length. In addition they outlast all other brands of pierce pin bigtime, 1,000 changes instead of 100 OR LESS!
So, by gutting the existing block, tapping the inside to 7/16-20(it was originally 7/16-16 which is a propietary size and no bolts can be found locally in it) and coring out a 7/16-20 bolt with a smaller(1/4-28) threaded hole for the pierce pin I got this:
The silver threaded plug is the old pierce pin block with it's new CCI pierce pin.
In addition I wanted to add an AGD Sydarm type front load port and that looks like this:
I've got to retune the springs to the new arrangement of parts inside and she'll be ready to rock. With the velocity at 240 it gets over 30 shots! I've also got to mill out a depression in the back of the pierce pin block for the valve spring to fit into, I'll get that tonight at work. It's getting there!
