The modern Blue streak trigger group.(Updated 8/16/14 RVA

If you call up Crosman and order a trigger group for the C9(Blue Streak),this is what you will receive.

I am going to convert this to work with a PMI-1 gun and put it in a stock. The red arrow is pointing to a safety that keeps you from firing the Blue Streak with the breach open. This is not needed for the Sheridan paintball gun, so that gets cut off. The black arrow points to the forward nub on the sear, this interferes with the hammer, so that gets cut off. This is what I came up with.

The top picture shows the unmodified trigger group to the first mod trigger group.
The next picture points to the back nub of the sear, with this quick mod the gun functioned what seemed perfectly, with the sear catching on the roll pin of the Sheridan hammer. I was fine with this...as I was under the poor assumption that this is what the roll pin what there for.

In the not so distant past I was politely corrected on this matter. The roll pin is just a guide to keep the hammer from spinning in the tube. Now this bothered me that my quick mod was not so correct, and the fact that I had another trigger group I was about to mod for another gun. So I opened it up and put some thought in to the issue. No worries, it was painful but I did not cause myself any permanent damage. I decided I could make a new sear. I found a angle bracket at the Home Depot that was the same thickness as the stock sear. Armed with my Dremel and some cutting wheels, a drill and a flat file, I came up with this.

I made 2 of them as I needed 2
This next picture shows the progression from stock sear to modded sear to custom.

I installed it and did some adjustment filing, and it works like a charm.

The red arrow shows where i cut more of the breach open safety off. I am currently working on a rva to go in that area.

They have both been tested but now I am going to take them out and try to harden them a little, with a blower some charcoal and some old motor oil.

Just thought some of you might find this useful.


EDIT: Update!!! RVA

So I have had this done for more than a year now so I figured about time I showed some pictures of the RVA.

So it is basicly just a pice of 3/4 aluminum rod that I had someone else center bore it for me(I could not get it straight on a drill press).

I tapped it all the way through for a 3/8 fine thread grub screw.

Now the 3/4 was just a hair to big for the 2 halves to close together all the way. I threaded a bolt through it, chucked the bolt in my drill and spun it high speed with some sand paper to shave the diamiter down a little.

Once fitted in place I put the two halves together and drilled a hole all the way through the trigger assembly and the rva. Take it apart, tap holes in rva to stop the body of the rva from spinning.
In the end it looks like this...

That is a kp spring, since boring the whole rva, I have room to use a longer spring.

The whole in the back to access the rva is smaller than the grub screw(just big enough for the allen wrench)so you can not back it out all the way and lose it.

Cool, what does one of those end up costing? So this drops into the stock, and you are attaching the stock with the usual pringle screw

they were under $20.
once you trim the tab off the trigger a rva can be fitted into the empty space.

They will drop into the modern C9 stock. You still have to get creative with the stock screw, as there is no hole on a P-series gun for the pringle screw.

Oh and smiley your thread about the 870 conversion is what made me realize I could fit a RVA in there.

The aluminum one BigOldschool made for me awhile back, based on the brass on I made by hand, as you can see it is very well made and I love it.
