Need to get Gene/Bob teamed up and create a new GRT.LOL
Can the Nitro Piston be bought from Crossman?
Stickstoff, the stroke is 1.85", the bore is 1"... swept volume is 1.45ci. Mine has the same scrape marks, it's the burr left on the piston when they cut the slot for the sear. Mine's going in the tumbler and getting slip coating.
BillK, it's a Rap4 stock with a nice solid section. I just turned it down for a tight fit (1" + a few thou) and stuffed it in. T
Could someone please grab me a pic?
BillK, it's a Rap4 stock with a nice solid section. I just turned it down for a tight fit (1" + a few thou) and stuffed it in. There is enough meat to cut the piston pocket and set the pin/screw, but I'm contemplating setting it in deeper and smoothing the transition between it and the pistol. That will require a metal insert for the pin, but I can make it look like it was designed that way (and gain a touch more LDC length).
I set the stock in deeper, and squared off the back of the pistol. They will overlap, once I notch the stock.
The stock change gave me a very useful 1-1/4" to put into LDC volume. I'm pretty sure I have enough space now to make something quite effective. It will be the first LDC I've built... we'll see.
